REPORT—1854. 
Sugar and Starch were given, a certain portion of each was mixed with the 
limited food, so that all except the free Starch being saccharine, the greater 
would be the relish for it, and hence we have much more of Starch consumed 
in pen 3 than in pen 4. 
But there is another point that should be noticed before leaving the 
question of the dieting of the animals. In a previous experiment with 
pigs, in which some of them which were fed on food comparatively de¬ 
fective in mineral matter suffered considerably in health, a mixture uf 
coal and wood ashes, superphosphate of lime and common salt was given 
with the best effects. It was thought, therefore, that in this case, in 
which lentils, sugar, and starch were all somewhat deficient, particularly 
in phosphates, a similar mixture might be useful. Accordingly a mixtures 
20 lbs. of the ashes, 2£ lbs. superphosphate of lime, and lbs. of common 
salt were divided into four parts, ami one of the fourths given to each pw 
this amount being distributed over fourteen days. This mineral mixture 
always taken with the greatest avidity and relish; so much so, that the amra 
would leave their other troughs the moment the fresh supply ot P 
within their reach. They were, moreover, upon the whole, very 
throughout the experiment, and yielded good rates of increase. , 
In the next Tabic (IV.) is shown the per-centagc proportion o^ ^ 
food, in which each of the separate articles was consumed during 
cessive periods as the experiment progressed.
