ration consisted of such a portion of one of the other alimentary sub- 

 stances before mentioned as was found sufficient by a careful weigh- 

 ing during the five weeks to keep each lot in the same healthy con- 

 dition. The following table shows the current progress of the ex- 

 periment ; the quantity of water drunk by each lot of sheep during 

 the five weeks being also measured, by a guaged trough. The au- 

 thor concludes that fifteen pounds of dry lucern may be considered 

 as a proper ration for one sheep per week, or rather more than two 

 pounds per day. The primitive weight of each lot, as before ob- 

 served, was four hundred and thirty six pounds.

1st, Dry lucern, 



2d, Lucern and oil cake, 



3d, Lucern, oats and barley, 



4th, Lucern and crude potatoes, 



5th, Lucern and cooked potatoes, 



6th, Lucern and Beets,

The quantity of water drunk by the seven lots during the five 

 weeks was as follows, showing the relative degree of thirst occasion- 

 ed by the different aliments. 



1st lot, 223 quarts. 6th lot, 108 quarts. 



2nd lot, 189 6th lot, 95 



3d lot, 164 7th lot, 36 



4th lot, 123 

 Fifteen pounds of dry lucern being considered as a proper ration 

 for one sheep per week, or seven and a half pounds a half ration, he 

 finds that the following quantities of each of the other aliments are 

 equivalent in nutritive value to the half ration of lucern. 



Oil cake. Barley. Oats. Crude potatoes. Cooked potatoes. Beets, Carrots. 



44 lbs. 34 lbs. 5 lbs. 14 lbs. 13 lbs. 164 lbs. 23 lbs. 



Thus taking the quantity of lucern as a standard the nutritive 



powers of the different substances will be
