her tra&s are more obfoure, and fhuns the view of our 
moftfoilicitous Inquiry. 
2 . But fince life and the w hole Oeeommia Animdis con- 
Lifts chiefly in the fiuider Parts of our Bodies; I have al- 
wayes thought it a too narrow confinement of Anatomy, 
when reftrained only to the learch of the Containing Parts. 
The Contained likewife and Fluids are capable of an Ana- 
lysis , if not by the knife, yet fire : and the various mix- 
tures made of them with Acids and Alkali's of various 
forts and confidences ; and obforving thence the various 
Refolts of Fermentations, Ebullitions, Coagulations , altera- 
tions in Colours , and other Qualities, will afford abundance 
of curious and inftruQdve fpeculations : and I would have 
not only a view to be made of all the Humours in each An- 
gle fubject, but upon the whole a Reflection to be made ; 
and from foch a flock of Experiments, we may warrant 
an Inference, and be more happy in our gueffes about the 
ufos of the Parts, and the Offices they perform in this 
Oeconomy. 
3; The PJychologia likewifo will here deforve to be con- 
fidered. Senfation and Motion, and what other functions 
there are of the foul, by fuch a Comparative Purvey may 
be rendered more intelligible ; and from a clearer know- 
ledge of them in Brutes, at length we may come the bet- 
ter to know our folves. 
4. Laftly, Embryotomia and the Hiffory of Generation .. 
Thefo as they will require a great deal of Labour in the 
Referch, fo will they abundantly recompenee the Pains, 
by the great plenty they will afford of fruitful Obforva- 
tions. Nature viewed in her naked form, in the firft 
organization of Animal Bodies, before fhe hath drawn 
over the veil of fiefh, and obfouredher firft lines by the 
focceeding varnifh of her laft hand , more freely dif- 
plays herlelf, and l’uffers us to behold the disjoynted Parts 
of this admirable Machine, and how it is that in time Hie 
puts them all together : this certainly will be of the great- 
eft confoquence both for the knowing the.ftruCture and 
the ufes of the. Parts.
