any regular Thinker without my Help but all are not such and the Prejudices general and inveterate and of some thousands of Years standing having continued through all Ages to this day and I would fain quite put out this false Light that like Will of the Wisp has brought many a Man into the Pit of Destruction or Grave while Physicians were guided thereby Therefore it being no slight Work to undeceive many and a very good Work if possible to undeceive all I will left what I have said be not sufficient to that end add somewhat more to the same purpose though I doubt some will not be convinced till I shew them how Things while at Stomach may cause all the Effects of Opium by a sensible Operation without the Help of Fumes Vapours Effluvia's Aura or any any such thing which have been the Asylum of the short-sighted that could see no other Means and therefore as was said concluded Things must be as they thought presuming that nothing could be that they did not see A special Inference and a very improving one which must cause People never to seek for any thing For why should they that think there is nothing but what they see look any farther To proceed then 14. It is agreed on all hands as I take it That the Animal Spirits are not generated till there is an Appulse of the Bloud at the Brain Can it therefore be imagined That Indulgent and Wise Nature should contrive a speedier Way to destroy diminish or disable the Spirits by Fumes and Vapours out of the Stomach than to generate them These are not the Ways of Equal Nature which destroy● and generates by the same Road so that if Animal Spirits are generated by the Bloud they are diminished by some Defect therein as want of Matter in the Bloud for that purpose the Bloud not arriving at the Brain and the like Note That I spoke in the last Paragraph of diminishing or destroying not bare disabling the Spirits for the Spirits or sensitive Soul may be depressed or disabled for some time and excited or elevated by other means than that of the Bloud as by Pleasure or Displeasure Ioy or Grief c. Thus good News or the Pleasure of any of the Senses enliven invigorate or elevate the Spirits or sensitive Soul in a moment this is the way that God has provided for us upon sudden Exigencies Deliquiums Lepothymies c. and thus Cordials work so speedily as you 'll find hereafter so may there be a sudden Depression of the Spirits as by ill News Pain c. which if you 'll be pleased to remember will much illustrate Things hereafter 15. The ordinary Strainers of the Body are so ordered that they will not admit Particles of another Figure especially if larger than the proper Particles much more should it be so with the Principal Strainer of the whole Body I mean the Brain both for its safety and of the whole which depends upon the Animal Spirits that are strained or separated from the Bloud in the Brain therefore the Particles of Opium which are esteem'd gross by all however are more so than the most tenuious Animal Spirits cannot enter into the Pores of the Brain to diminish or disable the Animal Spirits in case its Fume arrived there 16. It was never the Method of Nature to send Things crude unprepared and undigested into the inmost and principal Recesses and Parts of the Body without passing gradually by the several Digestions Concoctions Changes Percolations Circulations c. preparatory thereunto therefore it will not permit crude and indigested Fumes any access to the Brain till they have as it were performed their Quarentine elsewhere nor will Nature which always acts consentaneous to it self provide any Passage for such rude and crude Foreigners and Strangers to ravage the principal Part of an Animal 17. They cannot pass by the Arteries which carry nothing out of the Stomach but all into it or towards it and that with a violent Motion which opposes any thing that would pass that way 18. Nor by the Veins which carry nothing into the Brain but if they enter'd the Veins at Stomach they must thence pass into the Right Ventricle of the Heart where being rarefied by Heat they must take up much room and sadly discompose the Motion of the Bloud and also enter this principal Part in a crude condition tho' much better able to bear them than the Brain then must they pass into the Lungs where you may be sure they will be so saucy as to take up the uppermost Room and how they will be brought down again into the Left Ventricle of the Heart which they must vouchsase to do before they can get into the Brain none can tell There then must they stick and cause an Asthma unless the Man has the good Luck to be rid of these Rov●rs by ●thing and then Joy be with them as there wi● be when they are gone they are lost and never arrive at the Brain And if it could be conceived that they condescended to come down from the Lungs contrary to their Levity which is not to be thought what Pranks must they play in 〈◊〉 Left Ventricle of the Heart and what at 〈◊〉 considering it cannot bear the 〈◊〉 〈◊〉 〈◊〉 has been shewn whereas in this Case there must be a continual Stream thereof and consequently a discontinuance of the Bloud and its Motion See then how little Thought they must have that assert it is convey'd with the Bloud either to the Veins or Arteries 19. Nor by the Lympheducts for then they must contrary to their natural Levity descend into the Receptaculum Chyli and out of the Subclavials into the Right Ventricle of the Heart and afterward run all that wild Risque mentioned in the last Paragraph which was shewn to be impossible 20. Nor by the Nerves for then they must either run up in the Road of the Animal Spirits or in some By-way If they passed by the Road of the Spirits then must the Spirits be stopp'd for that time which is no short one and we suffer a Paralysis of the Stomach all that time or be much disturbed and interrupted then should we have Convulsions or at least some degree of a Paral●sis of the Stomach And if they passed by some By-way or Road besides that of the Animal Spirits then must it be a full or an empty one if full that Humour as suppose a Succus Nutricius for once must be disturbed and discontinued as the Animal Spirits were shown to be and if empty it would follow that Nature had void and useless Ducts which none ever had the Folly or Confidence to assert or that Nature contrived them for that purpose which is as has been shown directly against its Methods and Advantage But after all whither would you have them march in this By-Road for they could not mix or communicate as good Luck is with the Spirits and if they did it is
