into it were uncorrupt and sound nor in any of them could we find what we very confidently presumed to be there viz. the Bullet Wherefore I resolved to seek it the way by which it must have entred and accordingly dividing the Trachea at its insertion to the Lungs I thrust in a bended Probe to the left branch and there felt him lying loose about two inches within it which with my fingers I easily expressed at the divided end of the pipe to do which I laid it bare so far as where the Bullet had lodged and I protest to my wonder I found it not any way injured or altered by hardness erosion c. though the Bullet had divers impressions from the later The sanguiferous vessels though lacerated and cut in the dissection did yield little or no Blood either fluid or coagulate Thus far is true History and matter of fact I must now beg your pardon if I presume to give my sense and apprehension of some of those Phaenomena here related The extenuation of the body the absumption of the serum in the Heart-bag and the contraction of the Heart were the effects of the Tabes and that occasioned by the Bullets injuring the Lungs and pectoral vessels The lump of coagulate blood found under the Heart-bag was extravasate from the rotted veins and arteries of the Lungs That strange substance lodged between the Pericardium and the Bullet was either a Polypus and the excrescence of some part or it was generated by nature and substituted for a cushion to defend the Heart from injury by so uneasie a neighbour That Polypuses have been found in the Heart is affirmed by Nicolas Tulpius Marcellus Malpighius G. Garnarus c. but their shape and texture differing vastly from that of ours giveth reason to believe this to be none especially considering that they all excrescing from the Heart or some carneous part are inseparably united and radicated to their original and are spungy whereas this was nothing less having no root nor so much as an adhesion any where saving at the tail the small end of which being rotted by the Lungs into which it continued did easily divide upon my endeavour to draw it out the body of it also lay loose in the aforesaid interstice and as easily slipped out as a Wen or a Struma when the containing parts are opened It s substance was not fungous but of a soft firmness like a Kidney and in what ever circumstances it may resemble a Polypus as it doth the figure of that of the Nose vide N. Tulpii ob med lib. 1. obs 26. yet it also differs from all other excrescences besides in what hath been mentioned in that it was not rooted in any fleshy bony or muculous part and such the Lungs are well known not to be it must therefore be the stupendious effect of Natures industry and laid as a cushion to defend the Heart c. It s composition being so delicately soft and yet firm enough for such a purpose Its magnitude situation c. concurring also to confirm this opinion concerning it besides which I do almost remember and believe though I cannot be positive that the pulsant pain he had so violently in his Breast toward the left side decreased gradatim from the time of the deglutition if that be true whatever the substance were or its cause its effects were very propitious manifesting nature to be not only a diligent supplier of her own defects but as industrious to produce strange and unaccountable relief in such emergencies as this before us A resembling story we have from A Pareus lib. 8. cap. 15. The abscess was without doubt from a Phlegmon of the Lungs and because for the most part it was below or beyond the Bullet it proceeded rather from its obstructing and so stagnating the Blood and recrements in that Lobe than from extravasation What occurred of the latter was expectorated or remained in such Coagulums as that found under the Heart The cause of the Bullets falling rather into the left than the right Ramus of the Trachea is obvious from the more supine and direct figure thereof corresponding with the trunk as the figure doth manifest which consideration together with the Bullets being loose in the pipe renders the unsuccessfulness of Dr. Mayow's attempt very wonderful I am inclined to believe it was so either for want of a more early trial or a more skilful tryer than him who was employed about it The way was ingeniously contrived and as the Doctor himself told me had been successfully experienced in the like occasion Certainly had not the distance of the Doctors abode and very important avocations denied his personal assistance or had any other person skilled in Anatomy c. been substituted the Bullet from his own favourable shape and more propitious gravity and particularly from the strong efflations they provoked together with the assistant posture of the body would have been extruded Had they instead of hanging him perpendicular made him incline a little to the right side to have made the left Ramus more prone and at the same time made him distend the pipes by sucking in as much breath as they could contain their other means might have been effectual which I am induced to presume from the prosperous effects of the like attempt and yet wanting many of their advantages I mean the reversion of a Stone when sticking and not able to pass through the Urinary Channels Let any Physicians seriously perpend the difficulty of this with the advantages for the former and they will justifie my opinion The erosion of the Pleura and Diaphragme was from the acidity of the matter gnawing and corrupting them for though the Trachea wonderfully escaped such impressions the Bullet discovered on its superficies divers marks of erosion which all acids produce with much facility upon the saccharous or saline parts of Lead as is to be seen by immersing it in vinegar And now Sir to relieve your patience no less than my own perhaps already wearied with the prolixity of this Narrative give me leave to conclude with suggesting that I am of a belief having perused most of the publick accounts of this kind that scarcely a rarer accident and accompanied with such stupendious circumstances hath occurred to the present age than this that an extraneous body so large so heavy so hard should slip down that difficult and unusual way of the Weason and abide so long in the organs of respiration in so aged a person admitting after it such exercises as he performed Riding Marriage c. that nature should so unaccountably provide such a pertinent sence against injuries accidentally accruing and that even the smallest Ramifications of the Trachea though immersed in such a Cadaver should be preserved from injury thereby I am sure in the voluminous Observations of Schenckius Horstius Riverius Bartholine Burnet c. nor among all the stories in Mr. Oldenburg's Transactions or the Miscellanea Curiosa of the Leipswick Doctors hath it a Parallel This and whatever is else contained in this History as my 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 I submit to the better sense and reason of the Learned not presuming to be positive in any thing save in affirming my self c.

of this nature will be acceptable to the renowned Society I have adventured again to send you some of my farther Enquiries to be communicated to that learned Philosophical Company Since I wrote of the Blood of Eels and of young Eels I have not been idle to view Blood but especially my own which for some time I have indefatigably examined after that I had put it into all conceivable motions Among which Observations I well saw that the globuli of my own blood took the same figure which I formerly mentioned that the Globules of the blood of Eels appeared of to the eye upon seeing which I doubted again at the cause of the smart which the blood of the Eels causes in the eye These my many times repeated Observations of my own blood I made to no other end than if it were possible to observe the parts out of which the Globules of the blood consisted With observing this I found the globulous blood much more pliable than I did imagine the same before I have at several times bended these Globules before my eyes that they were three times as long as broad without breaking the Vesicule of them and besides I saw that the Globules of blood in passing by and through one another did by reason of their pliableness receive many sorts of figures and coming thence into a larger place they recovered their former globulosity which was a very great pleasure to observe and withal that the Globules of blood coming many together and growing cold thereby came to unite and made a matter very smooth wherein there were no more parts distinct to be taken notice of much after the same manner as if we supposed a Dish filled with balls of wax set over a fire by which they would quickly be melted together and united into one mass by which uniting of the Globules I concluded this to be the reason of the accident which is called the cold fire and of that also which causes the hands or fingers to be lost by cold but I leave this to others And I did very clearly also discover that there were six other smaller Globules of blood contained within each of the former and larger Globulous Vesicles and withal I took much pains to observe the number of the same very small globules out of which the greater Globules do consist that at last I strongly imagined that every of the greater Globules consisted of six smaller Globules no less pliable than the aforesaid for oftentimes I saw very clearly how the small Globules joyned and adapted themselves according to the figure the Vesicle or larger Globule stretched at length had taken being themselves stretched after the same manner and thus made one of the larger Globules stretcht out to appear by the lesser within it stretched also with it as if it consisted of long threads Moreover I put the greater Globules into so violent a motion that their Vesicles burst in pieces and then the lesser Globules appeared plainly to be scattered This first Globule I can see as plainly and great as with the naked eye one should look upon the eggs or spawn of a Cod-fish About nine or ten years since Dr. Graff opened in my presence the vein of a Dog and let out so much blood that the Dog grew faint then he opened the Artery of another Dog and by a pipe transfused the blood of this second into the first whereby the first was recovered the second was faint Then the said Doctor injected back into the Artery of the second a quantity of Cows milk supposing thereby to preserve the second dog alive saying milk was blood but no sooner was the milk put into the artery but the dog died And whereas 't is commonly said that milk is Blood therefore I shall relate of what parts the Milk consists so far as I have hitherto discovered I have said heretofore that the Milk doth consist of Globules swimming in a thin clear watery matter which we call Whey but as the great Globuli of Blood are all of the same bigness so in the Milk they are quite differing being of as many sizes and magnitudes as we can imagine between the smallest sand and a barely corn all of them being as clear as Crystal save only that through and between the same drive some irregular particles for the most part rounded these had a fatty substance which I imagined to be the latter their irregularity I imagined came from the impression of the encompassing Globules made on them in which posture they grew cold Viewing the aforesaid differences of the Milk Globules I supposed that the Milk vessels have no other parts included but the matter out of which they are all made and that the same matter so long as included in the vessels consisted of one uniform matter so that one could not distinguish parts and that the same vessels discharging this uniform matter into other vessels containing a substance of a quite differing nature which I suppose to be the Whey comes to be separated into these Globules of so differing magnitudes This may be represented by having two vessels filled the one with Fat representing Whey the other with Quicksilver resembling the uniform matter of the Milk these blended together the Quicksilver will be separated into small Globules of differing magnitudes and kept distinct by the fat Or further it may be explained by a dissolution of some gums in Spirit of Wine a drop of which being put into rain water which I compare to Whey the Gum becomes separated immediately into an incredible number of small clear Globules which makes it appear also as white as Milk it self and thence I suppose that the whiteness of Milk hath the same cause I have been often minded by some that flesh was nothing else but clodded blood yet for all my endeavours I was never able to find the first particles of blood in the fibers of the flesh but only such as are contained in the first Globules The last Summer being sickly for some weeks I voided much Flegm which was green tough and acid in the throat which yet continues but nothing near so much as before and some of it which I voided in the morning was of so heavy a matter that it sunk in the water the ponderosity of it I found to proceed from its not being filled with airy bubbles which most Flegms are mixed with By this means I observed my Flegm very often and found it to consist of tough slimy moisture mixt with many Globules and the tougher the Flegm was the greater was the quantity of Globules and from them also proceeded the green colour of it All these Globules were of one and the same bigness with the first Globules of the blood and indeed the blood is of the same make but only of a different colour for as I observed the greater blood Globules to consist of six lesser so here I could see them more plain only they seemed more slender and tender
