Tills result agrees well witli those obtained by Sclmlze 

 & Marcker iix tiieir experiments on sheep, already referred 

 to on page 152. These experiments were made on the 

 same two sheep which were nsed in the above experiments 

 by Ilenneberg, and also on two others of the same breed. 



If J following "Wolff, we divide the twenty experiments 

 which were made, into two groups, according to the total 

 amount of digestible nutrients, and then subdivide these 

 groups according to the wider or narrower nutritive ratio, 

 we obtain the following averages, each of five experiments, 

 per day and 1,000 lbs. live- weight :

Plainly, the third ration gave, on the whole, the most 

 satisfactory results, and it will be seen that it corresponds 

 quite closely with the results of Henneberg's exp#riment% 

 while the average of the first three does not vary much 

 from it, vi2. : 



Digestible probein 1 24 poxiiids. 



'' carbhydrates and fafe 10.24 '' 



IsTutiitive ratio 1:83 



It was also found in these experiments that, as in the 

 case of oxen, a too narrow nutritive ratio is to be avoided 

 in simple feeding for maintenance.
