It will be seen at a glance, from the foregoing analyses, that the date 
stones are very much richer than the peach and prune shells in all 
three of the more important constituents of fodder ; namely, the albumi- 
noids, the carbohydrates, and the fats. It is to be noticed, however, 
that this fact is neither surprising nor unexpected, for the compact 
date stone comprises both shell and kernel (7.e., both stone and meat) ; 
while, in the case of the peach and prune stones, the shells alone were 
analyzed after the kernel proper had been carefully removed. 
The composition of the date stones, as exhibited by the analyses, is 
really quite interesting, inasmuch as it differs decidedly from that of all the 
foddering materials that have been examined hitherto. The use of the 
date stones as fodder is explained and justified by the analyses, since 
it is made plain that they are rich in fat and in carbohydrates, and that 
they contain a fair proportion of albuminoids also, while they are by 
no means very highly charged with cellulose. 
It will be seen from the following table f of the average composition 
* The ethereal extract from the powdered date stones left, when dried, a 
remarkably pure fat. In both instances, the residue was a clear light-brown 
oil, that remained fluid at the ordinary temperature of the air.
