6 A Preliminary Difcourfe concerning Anatomy 
The Injuries they do, how to be avoided or remedied. 
Thewayes of taking, preferving, propagating or de- 
ftroying them. 
Former Naturalifts in their Hiftories have contented 
themfelves with more or fewer of thefe Inquiries, in 
which yet they too too oft mifguide us by their Accounts 
taken from unfaithful Relators, or the fabulous Records 
of the Antients ; naufeating and obfcuring the whole by 
tedious Philological Harangues, or troublefbme quotati- 
ons for the confronting or eftablifhing the Opinions of 
forne ; relying on others, when Autopfie, and their own 
Experience can only inform them ; and their Confidence 
and eyes may be as a thoufand Witneffes. I cannot lee 
how a Natural Hiftory of Animals can be writ without 
Zootomy ; at beft their Accounts can be but fuperficial, 
and by them we may know a Pig from a Dog, or that 
this is a Bull, a Bear or Monky ; but ftill remain ignorant 
of the curious Contrivance and Mechanifme of Nature 
within ; juft as if a perlon fhould think he had fuffici- 
ently defcribed a Watch, when he had only taken notice 
of the Cafe, the Studs, the Glafs, the figures and hand ; 
by this he may know it to be perhaps a Watch, but knows 
not how it fb exabtly mealures time. This moft neceffa- 
ry part therefore and moft inftrubtive, 
The Anatomical Account may contain, 
i . An accurate Diffebtion and Defcription of all the 
fold Parts, to be illuftrated (where neceffary) with Fi- 
gures ; and herein to be mentioned not only their Site, 
Number, Figure, Colour, Magnitude, their Cavities, Vef- 
fels, Integuments, Subftances, Ligaments, and Commu- 
nications they have with other Parts, but likewife in fome, 
a more ftribt fcrutiny may be made into their utmoft Tex- 
tures, by unravelling the fame, and by the affiftances of 
Glades and other Methods. Thus viewing Nature where 
file more plainly difcovers herfelf, by the Logick of a fair 
Analogy we may conclude line works the fame, where yet
