two subjects, were fed with the meat, and the third was nourished exclusively upon 
potatoes. As we have said, the meat-flour was accompanied by potatoes, and the mix- 
ture, to which was added 16 grains of common salt, was always reduced to a kind of 
broth by means of tepid water. The nourishment of the first lot was completed by 
10.7 grams of the phosphate of soda, and 4.4 grams of chloride of potassium. To 
that of the second lot was added an equal mixture of phosphate and carbonate of 
lime. The mixture of meat and potatoes was consumed with avidity, and from the 
third day the animals of the first lot evinced so great an appetite that their ration was 
increased by the addition of potatoes. 
During the forty-four days of the experiment, the animals of the first lot each con- 
sumed 219 kilograms (about 500 pounds) of potatoes, and 10.37 kilograms (25 pounds) 
of animal farina. Those of the second lot ate 208.75 kilograms (485 pounds) of pota- 
toes, and 10.37 kilograms (25 pounds) of meat; while the hog of the third lot consumed 
207.75 kilograms (424 pounds) of potatoes. At the close of the experiment the animals 
weighed as follows:

As will be seen, a small addition of meat farina to the potatoes was sufficient to 
double the weight of the animals during the period of the experiment. The result 
shows that 100 pounds of potatoes alone gave an increase of 14 pounds in weight, 
while the same quantity of potatoes mixed with a small ration of meat-flour, (11 
pounds, ) in the same duration of time provided an increase of 29 pounds in weight. 
ALCOHOL IN BREAD.—Mr. Thomas Bolas, in a communication to the 
Chemical News of May 30, states that the idea that the alcohol formed 
in the panary fermentation of bread is completely removed by the pro- 
cess of baking, is a mistaken one. By experiment he has established 
the fact that when about two ounces of ordinary bread is mixed with 
water and distilled, and the distillate is afterward purified, a percepti- 
ble quantity of aicohol may be obtained. Quantitative examinations of 
six samples of new bread, purchased at different shops in London, show 
the following results:

SUPPOSED AMERICAN ORIGIN OF RUBUS ID AUS, (THE GARDEN RASP- 
BERRY.)—Our cultivated raspberry is an importation from Europe. Our 
native red raspberry, (2. strigosus,) however, is so near it that the 
specific distinctness has been in doubt; and specimens from British 
America and the Rocky Mountains certainly occur which a botanist
