genous matter of a ration has a decided influence on the growth 

 of the wool, for Lots V and VI, wiiose ration was intermediate in 

 character, gave very nearly as much wool as Lot IV. 



In the experiments of 1888, already referred to, the percentage 

 was not so great in favor of the lambs fed on nitrogenous food. 

 For the sake of comparison, both are given below : 



In experiments of 1889, Lot IV pave 72 per cent, more wool than Lot III. 

 In experiments of 1888, Lot I gave 55 per cent, more wool than Lot II. 



The nutritive ratios of the rations were as follows : 



1889 — Lot IV, I .-4.2 ; Lot III, I : 10.9. 

 188S— Lot I, 1:3. 3; Lot II, I : 8.4. 



"While both were wider in 1889 than in 1888, there was a greater 

 difference between them this year than last. 



THE DRESSED WEIGHT AND INTERNAL ORGANS. 



The lambs were slaughtered on April 25th. The blood was 

 carefully caught in a clean pail, and it and all the important in- 

 ternal organs were weighed. The carcasses were hung up in a 

 cool place to stiffen for two days, and were then cut up, and the 

 parts carefully examined. Before they were taken down, how- 

 ever, the)^ were weighed and most carefully inspected by the dif- 

 ferent members of the staff. The most striking difference that was 

 apparent, as thfe carcasses hung upon the hooks, and after they 

 were cut up, was the evident leanness of the two belonging to Lot 

 IV (fed nitrogenous food.) The kidneys were not covered, and 

 there was very little loose fat next the skin, while in all the other 

 carcas.ses the kidneys were more or less corapletel}^ covered, and 

 there was a layer of tallow of greater or lesser thickness between 

 the skin and bod3^ The carcas.ses of Lot III had the most of this 

 tallow. The same thing is .shown in the amount of caul fat and 

 kidney fat, as shown in the table of weights following. While an 

 expert butcher would have undoubtedly selected the carcasses of 

 Lots V and VI as furnishing the most saleable mutton, the car- 

 ca.s.ses of Lot IV had little or no unpalatable adipo.se matter, and 

 those of Lot III showed much the largest percentage of waste, fat- 

 t}' matter about the root of the tail and in the flanks. 



In the table below is shown the weights of the dres.sed carca.sses 

 and the various organs for each animal, and the averages for each lot:
