With a view of ascertaining the chemical results of feeding horses 
upon these aliments separately and combinedly, six horses devoted 
to experiment were put into three classes, and each class were fed 
on a diet consisting of hay, straw, and oats, but in different pro¬ 
portions for each class. 
For ten or twelve days succeeding the commencement of the 
experiment, the dung and urine voided by each horse were care¬ 
fully collected; and these matters were analysed in a manner to 
determine the quantities of water, organic substances, ashes, and 
mineral salts, contained in them. The analysis led to the follow¬ 
ing results:— 
In all three classes the dung-balls exhibited an analogous com¬ 
position. On an average they have yielded 74*0 of water, 2 5 of 
ashes, and 23-5 of dry organic substance. The proportions repre¬ 
sent the average composition of the solid excrements of horses kept 
on the regulated ration. 
The urines have not presented great differences. All have ex¬ 
hibited an alcaline re-action, and all have been turbid, properties 
possessed by the urines of horses in general. The fluids have been 
filtrated with a view of separating their deposits, which, collected 
and weighed, has been afterwards analysed. 
The deposit has varied, in respect to weight, from 0 5 to 5*0, 
the weight of the urine. It was found to be the more abundant,
