Very little experimental work has been done with poultry 

 on this subject, not because it is not important, but because of 

 the physiological difficulty already mentioned, arising from the 

 fact that the fseces and urine unite in the cloaca before being 

 voided, which makes it very hard, indeed, to use poultry for 

 digestion studies with satisfactory results. However, there are 

 a few men who have attempted work along this line, and we 

 think with considerable success. Among these are Dr. Woods 

 of the Maine station, who obtained the results above shown. 

 He used capons because of their inactive habits, and caught 

 the fsc'ces in a rubber bag attached to them with a sort of har- 

 ness. His work shows that fowls are able to digest protein 

 almost as well as cows can. Note how well they handle beef 

 scrap and corn, but do only fairly well with oats, barley and 

 wheat, and very poorly with bran.
