We observe from the above that the per cent of albumi- 
noids is considerably higher in each instance for the second 
cutting, and also the per cent of ash, while the variations 
in the other constituents are not marked. And further, 
there is shown what Wilson* has already called attention 
to, ‘That the difference in composition between different 
cuttings of the same grass is far greater than that between 
different grasses cut at the same stage.” 
FODDER ANALYSES. 
CRUDE FIBER. 
Probably in no other determination 1n fodder analysis is 
there likely to be so wide a variation in the results obtained 
by different chemists as in the fiber, due mainly to differ- 
ence in methods used and degree of heat employed during 
the determination. As time has permitted, I] have made a 
few trials for the purpose of ascertaing this difference. The 
results, with the methods employed, are given in this topic. 
In all the methods, so far as T know, the strength of the 
acid and alkali used is the same, 1. e€., 200 c.c. of a 1.95 per
