Trillat and Forestier (14) report 6.98 as the average of 10 samples from 
ewes of the Roquefort region of France, and Sanna (13) gives 7.53 as the 
average of 55 samples from sheep in southern Sardinia. 
For the nonmilk breeds Fuller and Kleinheinz (5), of the Wisconsin 
Station, give the following analyses: Oxford, 7.65; Southdown, 8.4; Dor¬ 
set, 7.2; Shropshire, 5.88; Merino, 6.00; and Montana, 7.15. These figures 
represent the averages of several individuals of each breed, which com¬ 
pare very closely with averages obtained at this station. 
Tables I and II give the analyses of 158 samples of ewes' milk. 
They represent 95 ewes of 6 distinct breeds and 11 crosses, the individual 
animals ranging in age from 1 to 8 years. Each sample represents a 
composite of three or more milkings, taken on an equal number of days 
from one nipple, which was milked dry, the lambs being kept apart from 
ewes from 11 a. m. to 1 p. m., when the samples were drawn. All sam¬ 
ples were taken approximately one month after lambing, which repre¬ 
sents the period of lactation when the maximum yield would be expected 
under normal conditions.
