M. E. Peligot on the Composition of Asses' Milk. 81 



different kinds of nourishment for a continued time, and at the 

 end of not less than a fortnight of this uniform regimen, its milk 

 was submitted to analysis. 



1st Experiment. An ass was fed for a month with carrots 

 freed from their leaves : at the end of this time its milk con- 

 tained, in every 100 parts,

This milk, evaporated to dryness, appeared of an orange colour, 

 and exhaled the smell of carrots. This ass ate 18 kilogrammes 

 weight of carrots a-day, equal to 39 lb. 11 oz. 10 dr. 



%d Experiment. The same ass was then furnished with red 

 beet-root ; and, at the end of fifteen days its milk shewed the 



following composition :

This is the nourishment which made the milk most rich in solid 

 matter. The ass ate 21 kilogrammes of beet in the day, equal 

 to 46 lb. 5 oz. 9 dr. 



3d Experiment. To the same ass was given for a month 7 

 kilogrammes of bruised oats a-day, equal to 15 lb. 7oz. 3 dr., 

 and 3 kilogrammes of dry lucern, equal to 6 lb. 9 oz. 15 dr. ; its 

 milk, at the end of this time, contained

4fth Experiment. The same ass was fed for a fortnight on po- 

 tatoes, and its milk then supplied the following analysis :

From these analyses we are led to conclude, that the beet-root 

 is that nourishment which furnishes milk most rich in solid mat- 

 ter, next succeeds the mixture of lucern and oats, then the po- 

 tatoes, and lastly the carrots. M. Peligot, moreover, endeavour-
