Mr. Este takes the liberty of presenting to the Mana- 

 gers of the Royal Institution some statements in expla- 

 nation of the proposals he had the honor of submitting 

 to their consideration on December 14, 1808, to assist 

 their judgment in forming a decision upon the propriety 

 and advantage of admitting demonstrations on drawings, 

 models, and on engravings, necessary to illustrate so 

 much of the structure and organization of man and 

 other animals, as he conceives may be illustrated with 

 the strictest decorum, and without giving the slightest 

 offence, to an audience consisting of both sexes. 



Anatomy and physiology are too intimately connected 

 to be considered separately ; inasmuch as physiology 

 explains the animal functions, or, in other words, the 

 uses of the different organs, while anatomy shows their 

 structure; the uses of the organs can never be rendered 

 intelligible till their structure is understood ; the de- 

 monstrations of structure must therefore naturally be 

 associated with the reasonings upon the uses. 



Mr. Este respectfully requests permission to state 

 his opinion, that nearly the whole of the animal economy 

 may be comprised in the lectures he proposes to deliver ; 

 that almost all the organs, and all their functions may 

 be exhibited, as well as explained ; and trusts that the 

 following statement may disclose his plan, and furnish 

 sufficient data to enable the managers to form their 

 decision. 



The drawings, models, and engravings, for their de- 

 monstrations, will be found to amount to little more than 

 such as are used for conveying instruction in the fine 

 arts ; and such as are frequently referred to in polished 

 society for elegant amusement ; such as Hans Holbein's 

 Dance of Death Monumental Sculpture, by Rou- 

 billiac, &c. 



I. As Architects, in raising an edifice, first lay a foun- 

 dation on which they build its parts, the SKELETON 

 giving shape and support to animal bodies should form 

 the first part of the course.
