Fat incorporated with the raw feed was without effect upon 

 the digestibility of the raw fibre. (2.) A dose of three quar- 

 ters of a pound of fat to 1000 pounds' live weight, and 18 to 

 20 pounds of organic matter in the feed, increased decidedly 

 the digestibility of the organic matter of the feed in general, 

 and especially of the proteine matter of the raw feed, and of 

 the non-nitrogenous extractive matter. (3.) This increased 

 digestibility of the nutritive matter was only true of clover 

 hay, and not of meadow grass. (4.) It appeared on calcula- 

 tion that clover hay, which loses, as was proved experiment- 

 ally, in digestibility by being stored for a month, and more 

 for a longer time, can not then be restored to its normal con- 

 dition, in this respect, by the addition of oil, the proteine mat- 

 ter being rendered as digestible as in well-cured hay, but the 

 non-nitrogenous extractive matter remaining ten per cent, 

 less digestible. (5.) The oil added seemed in the highest de- 

 gree digestible. (6.) The digestibility of raw feed, clover 

 hay, is, however, not so materially heightened by the addi- 

 tion of oil that it would pay to add it for this purpose ; but 

 since fresh clover hay possesses almost as high a degree of 

 digestibility as (and in some cases even higher than) old hay 

 treated with oil, it is decidedly advisable not to store such 

 hay longer than necessary before feeding it. (7.) Increase of 

 the dose of salt from 964 grains to 1928 grains per 1000 

 pounds of weight of the sheep seemed injurious to the diges- 

 tion of nutritive matter, while it caused a larger consumption 

 of feed. (8.) A better or worse effect of the feed, as indica- 

 ted by an increased or diminished increment of weight of 

 the animals, on the administration of oil or salt, could not be 

 recognized from the experiments. 8 (7, April 30, 1874, 158. 



INFLUENCE OF FOOD ON THE MILK PRODUCTION OF GOATS. 



Our late journals bring accounts of the continuation of the 

 experiments performed under the direction of Stohmann, at 

 the experiment station at Halb, in Germany, on the influence 

 of the food upon the milk production of goats. The results 

 are, in the main, in accordance with those of previous experi- 

 ments. The composition of the organic substance of the milk 

 was not essentially altered by changes in the composition of 

 the food. "The milk production was influenced by the 

 amount of water consumed. This observation, which is in
