330 APPENDIX. 



Sir. G. Hill witnessed a parallel case, where a much 

 greater increase of the weight of the body appeared to 

 result from the drinking of a single cup of tea. 



Mastication and Digestion. These have already been 

 treated of at pages 106 and 112, and we shall proceed to 

 describe more distinctly than has been done in the forego- 

 ing treatise, the Anatomical structure of the human frame. 



The human body, it is known to all, is composed of 

 solids and fluids, united in different proportions. The 

 solids give form and consistence to the different parts, 

 and are composed of bones, ligaments, muscles, ten- 

 dons, nerves, and vessels containing various fluids. The 

 fluids form the largest proportion of the body, and con- 

 sist of blood, chyme, chyle, and all the secreted liquids, 

 as sweat, saliva, bile, tears, &c. These are all con- 

 tained in vessels, cells, cavities or reservoirs. 



It has been found, contrary to expectation, that when 

 the fluids of the human body are separated from the sol- 

 ids, their proportions are as eight to ten. Thus, a body 

 weighing 100 Ibs. contains only 20 Ibs. of solid matter, 

 the remaining 80 being composed of various fluids. This 

 has been ascertained by an examination of human bodies 

 found in a dried state in the sands of Arabia, where the 

 extreme aridity of the atmosphere prevents decomposi- 

 tion, and acts on dead animal matters only by the ab- 

 sorption of their fluid particles ; thus leaving the solid 

 parts in a perfect, though in greatly diminished propor- 

 tions, in appearance. 



Division of the Subject. Authors have divided the 

 anatomy of the solids into several branches, and named 

 them according to the parts of which they treat. These 

 are, 



1. Osteology. A description of the bones. 



2. Syndesmology. A description of the ligaments. 



3. Myology. A description of the muscles. 



What are the solids of the human frame '. Which form the largest portions 

 of the body, the .solids or fluids ? How is it known that the fluids form the 

 largest portions ? What are the proportions between the solids and fluids ?
