butter as weighed in so-called “ official ” tests, where the butter is 
simply “ washed and weighed.” In the test of Ida of St. Lambert 
by Mr. D. W. Watrous, in September, 1884, the butter was washed 
three times and weighed within twelve minutes after the buttermilk 
was removed from the churn, and was finally weighed as salted but- 
ter in less than five minutes afterward. It is highly probable that 
butter treated in- this way would contain a larger proportion of 
water than the small quantity obtained in our tests would after-being 
worked. It is, however, thought best, on account of the more uni- 
form condition of the dry butter, to take this as the true yield. The 
figures given are in every instance for unsalted butter. The analy- 
ses which have been made of this butter show it to contain a large 
proportion of butter fat and a small proportion of casein, while the 
water is not high. 
The results obtained for the whole period are given in the follow- 
ing table;
