It appears evident from the above table, that although in the 

 different kinds of meats and fish there is a slight variation in 

 the nature and proportion of nutritive matter, it is not such as 

 to account for the different facility with which they are digested 

 and dissolved in the stomach : this probably depends upon some 

 peculiarity in the solubility of the albuminous portion, and 

 which it is my intention more particularly to examine. 



The large proportion of water which is contained in muscular 

 fibre, and the great loss of weight which it consequently^suffers by 

 desiccation I long ago observed, and was inclined to attribute 

 it to a partial decomposition of the animal matter ; but the close 

 approximation of the results obtained by exposure to heat with 

 those afforded by drying in vacuo, aided by the absorbent 

 powers of sulphuric acid, show that no such decomposition 

 occurs, and that the loss of weight sustained by muscular fibre, 

 dried at 212°, may be referred without appretiable error, to the 

 evaporation of water only.
