 Stiaroconote, — This is a fatty matter, which occurs mixed with 

 the preceding. It is of a fawn colour, infusible and insipid, and by 

 combustion gives an acid charcoal. Neither alcohol nor aether dissolves 

 this substance ; both the fixed and volatile oils readily dissolve it. 

 Nitric acid takes it up after slight ebullition, and it reappears as a 

 white fat, which is acid, soluble in boiling alcohol, and crystallizes in 

 small laminae, similar to margaric and stearic acids. 

 This substance is composed of 



Carbon 59-832 



Hydrogen 9'246 



Azote 9-352 



Phosphorus 2420 



Sulphur 2030 



Oxygen 17*110

 Eliancephol. — This is a reddish liquid ; its taste is disagreeable : it 

 is soluble in aether, fixed and volatile oils, and alcohol, in all propor- 

 tions. When heated, this substance dissolves the other matters of the 

 brain readily, and these impart consistence to it. Its composition is 

 similar to the preceding. 



Cerebral Choleslerine. — A crystallizable fatty matter, which, accord- 

 ing to some authors, must be the result of some morbid change. The 

 constant and considerable quantity which M. Couerbe found in the 

 brain induces the belief that it is a widely diffused organic animal ele- 

 ment. It is well known that MM. Denis and Boudet have found it in 

 the blood. The cerebral cholesterine is perfectly similar to that of 

 biliary calculi. Their analyses gave M. Couerbe the same results : 



Carbon 84*895 



Hydrogen 12*099 



Oxygen 3006

 This analysis differs a little from that of M. Chevreul, as follows : 



Carbon 85-095 



Hydrogen 11-880 



Oxygen 3-025
