416 Dr. Scherer's Abstract of 



The results were,— 



I. II. 



Carbon 51'036 50-752 



Hydrogen... 6-801 6-761 



Nitrogen ... 17*225 17-225 



Oxygen 24-938 25-262 



100-000 100-000 



B. Compact Corneous Tissue. 



I. Hair of the beard, which gave 0'72 per cent, of ashes. 



II. Hair of the head (hght coloured), which gave 0-3 per 

 cent, of ashes. 



III. Hair of the head of a Mexican (very black), which gave 

 2 per cent, of ashes. 



IV. Brown hair from the head. 

 The analytical results were- — 



I. 



Carbon 51-529 



Hydrogen ... 6-687 

 Nitrogen 17-936 



Oxygen and 123.848

C. Buffalo horn purified as the other substances, gave 0-7 

 per cent, of ashes. 



With this and the hair, the relative volumes of nitrogen 

 and carbonic acid were found to be 1 : 7 when chromate of 

 lead was used. 



The nitrogen was also determined by the method of Will 

 and Plantamourto be 16=380 per cent., but came out 17-284 

 by a direct determination. 



The analytical results in four cases were — 



I, II. III. IV. 



Carbon 51-990 51-162 51*620 51-540 



Hydrogen ... 6-717 6-597 6-754 6-779

Nails and wool purified as usual gave the following results : — 



Nails. Wool.
