SOCIETY MEETINGS. 
and published by the Aylesbury Dairy Company and the society 
of chemists in Great Britain ; from these we may gather that 
Jerseys and Guernseys yield a milk relatively rich in fat, but 
poor in casein and sugar. Short-horns, Ayrshires, and Holsteins 
a more watery fluid, rich in casein, but relatively poor in blitter- 
fat and sugar; while Devons give milk nearly as rich in fat as 
the Jersey, and in casein as the Ayrshires, and richer than either 
in sugar. While the fat in a finely-divided natural emulsion is 
most useful and necessary in cell-growth, we are apt to over¬ 
value it and disregard the active agency of milk sugar, which, 
by its splitting into lactic acid in the digestive processes, causes 
the chemical changes in the phosphates and albuminates on 
which tissue-building and nutrition so largely depend. Hence 
the superiority of Devon milk, as shown in practical results. 
Skimmed milk yields a hard curd, difficult of digestion. The 
curd of cow’s milk being more dense than the light, flocculent 
curd of human milk, in artificial feeding we use sugar or starchy 
material to make the curd more porous or spongy. The milk 
of the buffalo, goat, and ass illustrates the same truth. Lehman 
says a cow properly fed should yield i per cent, of her weight 
The statistics kept by Dr. Morris (and they are certainly most 
complete and exhaustive, each sheet showing name, herd-book 
number, when dropped, when she calved, sex, color, and any 
peculiarity of calf, what became of it, if kept or sent to the 
butcher, when she comes in profit, the number of pounds of 
milk given each night and morning, when she is served and 
when due, her price and any peculiarities of her conformation, 
etc. ; these sheets, being carefully filed, give a complete life-his¬ 
tory of each cow and her offspring) .show that his cattle, which 
weigh from six to eight hundred pounds, have averaged him 
five-and-a-half times their weight, or about 3500 pounds of milk 
yearly (a most conservative estimate), on a feed of hay, corn- 
fodder cut green and mixed with hominy, bran, potatoes, and 
beets. He explained the method of the Devonshire people for 
raising cream and making butter, the sweet skimmed milk 
being fed to the calves. He has tried this process, but is now 
using a hand-separator, with which recently he obtained over 
four quarts of cream from twenty-eight quarts of milk (one 
pound of butter from seven quarts of milk), which he can use 
more profitably for calves than for pigs. After the talk Dr. 
Morris expressed a willingness to answer any questions put to 
him. He was kept busy for the next half-hour, being ques¬ 
tioned relative to almost every stage and era of dairy-breeding
