The distillate was collected iu three fractions, whilst from a further 
fraction a small quantity of the crystalline acid mentioned above was 
isolated. The acid present in the three first fractions were conver- 
ted into the silver salts which on analysis gave the following 
results : — 
Fraction — 
I' . . 0 0G47 gave 0’0352 Ag. Ag=54:‘4 per cent. 
II . . O' 131 4 gave 0 0598 Ag. Ag=45'5 ,, 
III . . 0-22 gave 0'0798 Ag. Ag=36'3 
Fraction I evidently consisted of the silver salt of butyric or isobutyric 
acid (C^HyOgAg requires Ag =55 '1 per cent) ; Fraction II ofhexoicacid 
(C.j,Hi 303 Ag requires Ag=45'4 per cent) ; Fraction III was not 
identified and evidently consisted of a mixture.
