Summary. 
I. The use of an excessive meat diet in rats induces a deteriora- 
tion in the health of the animals. This deterioration is shown in 
(a) an imperfect physical development, ( b ) a loss of reproductive 
power, ( c ) defective lactation, and (d) a high mortality in early life 
in the second generation of meat-fed subjects. 
II. The recuperative powers of these deteriorated animals, on a 
normal diet, is very striking. 
III. In animals deprived of their ovaries, the minimum amount 
of proteid required is less than in normal females.
