The cows used for the experiment were unpedigreed Jerseys, four in 
number, ; 
Emm, seven years old, dropped her last calf October 30, 1882, and 
not now in calf. 
Ann, seven years old, dropped last calf last of April, 1882, and due 
to calve in April, 1883. 
Meg, four years old, dropped her last calf December 4, 1883. 
Jem, two and a half years old, dropped her last calf October 24, 
1882. 
The food preceding the experiment was four pounds wheat bran and 
four pounds corn meal per cow daily, together with hay ad libitum. 
The normal weight of the cows may be calculated from the following 
data, the food being alike on the various intervals: From December 
10-12, average weight, seven hundred and nine pounds per cow; 
December 20-22, seven hundred and ten pounds per cow ; December 
30 to January 1, seven hundred and five pounds per cow; January 
5—7, seven hundred and nine pounds per cow; February 15-17, six 
hundred and eighty-five pounds per cow; February 25-27, seven hun- 
dred pounds per cow, or two thousand eight hundred and twelve 
pounds for the four cows. In like manner the normal milk yield 
calculated from the yield during these periods was 13.36 pounds. 
During the continuation of the experiments the hay was fed dry, 
cut in about half inch lengths. The grain was given separately in 
equal portions morning and night. ‘The water was weighed and each 
cow given, twice a day, what she would drink. ‘T'wo ounces of salt 
per cow were given each Sunday morning. ‘The waste food collected 
each day contained the hay only, except in the case of the gluten meal, 
which, being unpalatable to the cows, was only partially eaten. 
The remarks concerning the condition of the individual cows during 
the experiment period and preceding are as below: 
December 31. Emm seemed to be suffering from indigestion. 
January 11. Ann refused part of her morning’s bran, and no bran 
given her at night. | 
January 12. Meg refused part of her morning’s bran, and no bran 
given her at night. 
January 17. Emm and Jem refused part of their morning’s gluten 
meal, and none given them at night. 
January 18. All the cows sick of the gluten meal, yet eager for other 
food. ‘They would hardly touch the gluten meal, even when sprinkled 
on hay. 
J eer 19. Ann refused part of her morning’s gluten meal. 
January 22. Jem’s bowels rather loose. 
January 23. Emm seemed to suffer from the cold to-day, and ate 
but little of her morning’s hay. 
January 25. Hmm shows signs of slight colic, and refused to eat. 
January 29. Under hay, corn meal and ensilage Meg refused her 
morning’s feed, and received no ensilage or meal at night. 
The day’s milk for the purposes of analysis and for churning was 
the mixed evening’s and morning’s milk. ‘The milk was kept in deep 
cans in a cool place, and the churning was upon the fourth day, the 
milk previously having been set over night ina warm room. The 
whole milk was churned in a barrel churn, which rotated end over end. 
The butter, after being well worked, was then weighed, no salt being
