as a Food for Pigs.

more than a theoretical speculation, unsupported by actual ex- 
perience. At my suggestion Mr. Roberts, therefore, made 
another set of experiments, well calculated to throw light on 
this subject. Four home-bred pigs of one litter, about nine 
months old, and all males, were troughed at 11 A.M., on the 
oOth December, 1871 : — ibs.

All the pigs were fed upon malt-dust, palm-nut meal, and 
peas, and the pigs Nos. 1 and 2 received in addition Concentrated 
Mutton-soup, whilst the second pair had no additional food. 
Two tubs were set aside for the feeding experiments. The 
first contained the following food for Nos. 1 and 2 pigs : — 28 
lbs. of malt-dust boiled, 14 lbs. of palm-nut meal, and 14 lbs. 
of essence of mutton dissolved in boiling water. The second 
tub, for pigs Nos. 3 and 4, contained 28 lbs. of malt-dust boiled, 
and 14 lbs. of palm-nut meal, and no extract of mutton. 
To each pair of pigs 2 lbs. of whole peas were given at mid- 
day daily, and they received as much as they could eat of the 
prepared food from the two tubs every morning and evening. 
Both the tubs were finished at the evening meal on the 6th of 
January, 1872, and the pigs were weighed at 4 P.M. 
The tubs were refilled, that for pigs Nos. 1 and 2, with 28 lbs. 
of malt-dust, 14 lbs. of palm-nut meal, and 11 lbs. (the re- 
mainder of the keg) of Concentrated Mutton-soup, and the 
second tub with the same amount of food minus the mutton 
extract. 
On the 15th of January the contents of both tubs were con- 
sumed at the morning meal, and the little keg of Concentrated 
Mutton-soup being consumed, each tub was refilled with 28 lbs. 
of malt-dust and 14 lbs of palm-nut meal. 
The pigs were weighed on the 17th of January, at 4 P.M. : —
