into the Heart where it is subtilized and begins to be changed into Blood and by circulating several times from the Heart into the arteries from the arteries into the Veins and from the veins into the Heart again it is rendred proper to nourish the animal the subtiler parts whereof penetrating as vapours thro' the Tunicks of the arteries and joining and uniting themselves to the Parts nourish and augment them and the rest is drained into the Liver Reins Pancrea's c. and according to the Laws of Circulation repasses into the Veins and from the Veins into the Heart where it is refurnished with Spirits by the means of a Ferment which is contained in its Ventricles and by the Mixture of the Air which insinuates it self through the Lungs into the Heart I could prove by many Experiments That the pancreick Juice comes not from the Spleen to the Pancrea's Pag. 79. as you pretend But as the thing is of it self sufficiently clear and that we need but observe the structure of these two Viscera's and the communication that they have one with the other to convince you thereof It will be sufficient to cause you to take Notice of that which modern Anatomists have several times experimented That after the Spleen hath been taken from Dogs the Wound being consolidated these Dogs have been as well as if they still had their Spleen and we draw a pancreick Juice therefrom altogether like that which we ordinarily draw Wherefore if the Spleen did communicate this Juice to the Pancrea's it is certain That these Dogs whose Spleen was cut out would languish and Nutrition would no longer be perfectly made because the Chyle is not fermented with the Bile for want of the Pancreick Juice which is the Menstruum that dissolves these two Bodyes and which puts them in action there would also be no longer any secretion of the Cream of the Chyle from the Excrements and we could not be able to draw a Pancreick Juice from these Animals for the Cause being remov'd there is no longer any Effect sublata Causa tollitur Effectus The pancreick Juice comes not then from the Spleen to the Pancrea's but is a Liquor which is strained in the Pancrea's as the Serocity in the Reins It is not a vain Fancy as you go on to believe Pag. ●3 That the Lympha is a Serocity which is separated from the Blood and from the nervous Juice in the Glands if you had examined the substance of the Glans and the Vessels which terminate thereto you would judge otherwise thereof You would see that the Glands are as so many strainers through which the Serosity is strained and there terminates thereto four Sorts of Vessels namely Nerves Arteries Veins and the Lymphatick Vessels the Arteries carry Blood thereto which the Veins re-carry to the Heart according to the Laws of Circulation the Nerves carry the animal Spirits or nervous Juice thereto and the Lymphatick Vessels draw thereto the Lympha and is discharged thereof as I have already said into the thorachick Pipe and into the descending Vena cava You see from hence That since the Glands have no other Vessels which administer thereto but Nerves and Arteries it neceassrily follows That the Lympha is a Serocity which is separated from the Blood and from the nervous Juice in the Glands You say There is neither Acid nor Alkali in the Seed because that being the Decidu of or that which is fallen off from all the Body Pag. 109. and the Recidu of the last Aliment it suffers neither the one nor the other since they have been separated therefrom in the first Concoction of the Aliment and are not to be ound in the second which is the Haematose and yet less in the Third which is the assimilation or Nutrition of Parts You add That if there were Acid and Alkali in the Seed it would be destroy'd by the continual Ebbulition and Fermentation which is made thereof It is to be admired that you can be of this Opinion seeing according to the Doctrine which you would establish you cannot deny but the seed hath the same Principles as Flesh Blood Bones Horns and other parts of Animals and 't is otherwise indisputable That Meat Blood and Milk which grow sour when they corrupt contain Acid and the Volatile Alkali's which are drawn in abundance therefrom are Proofs no less certain That there is an Alkali therein whence it follows That these two Salts are also to be found in the Seed since according to what you affirm It is only the Residue of the last Aliment of of those parts as for the Objection which you make That if there were Acid and Alkali in the Seed it would be corrupted because of the continual Fermentation which is made theteof You shall also observe That these two Salts never act except they be dissolved or excited by some external Agent as Heat or by the mixture of some other Body as it happens when the Seed of the Male and that of the Female come to be mingled together and to be heated in the Womb for then all their parts are put into Motion and there is made a Patern or rough draught of all those of the Foetus the more subtile parts of the seed retire themselves to the Center and scatter to the Circumference those which their grossness or figure render less proper for motion from which are produced the Membranes which environ the Foetus and the more subtile parts continue their motion in the middle dis-intangling themselves from those whose figure is not proportionable to theirs and uniting themselves to those which are with them conformable and so those which are Decidued or fallen from the Brain or more properly those which are found proper to form the Brain unite together and produce the Brain Those which ought to form the Heart unite together and form the Heart and so of all the other parts and when it happens that the Man's Seed overpowers that of the Woman's there is formed a Man as there is formed a Woman when that of the Woman's is stronger than the Mans and we may believe that there may be an Hermaphrodite when both Seeds meet together in a perfect Equality Where you begin to treat of Acid and Alkali you tell us You can hardly give your Opinion thereof Pag 89. because it is difficult to declate it upon a matter which 'till now is undetermined yet nevertheless you as it seems decide it so absolutely as if it were the most known and determined Truth in the World. You pretend that Acid is a principle of Death and the Alkali a principle of Life Pag 96. that is to say That Acids are the Destroyers of Bodies and Alkali's on the contrary the Authors of their Construction For to make the Probability of this Maxim disappear one needs only to make reflection upon what I have spoken thereof in my Discourses upon Acid and Alkali where I have spoke of
