Miscellaneous Intelligence. 



We observe, for instance, that cows on a meadow, feeding only upon 

 grass, enjoy good health. Now let us endeavor to ascertain how we 

 can produce the same proportion of non-nitrogenous and nitrogenous 

 aliment with other descriptions of food. 



The proportion which exists in grass or hay is 1 to 8-3, as in the 

 following Table :

This Table, as given by Fresenius, is derived from German authorities, includ- 

 ing several results obtained and published by Dr. Thomson in his Researches on 

 Food, p. 167. See also Phil. Mag., vol. xxxii, p. 459. There is therefore some dis- 

 crepancy when compared with English grain, the German grain being richer in nitro- 

 ea See Dr. Thomson on the Composition of German and English Bread, Phil- 

 voL xxiii, p. 321. 



Were we then to give them carrots, in which 1 part nitrogenous is con- 

 tained for every 7*84 parts of non-nitrogenous constituents, the propor- 

 tion would not be materially disturbed ; but were we to give them pota- 

 toes (1 :9), we disturb the proportion somewhat more. It is therefore 

 expedient to feed them with a substance which is richer in nitrogen; 

 this proper proportion may be obtained with exactness by mixing 1 



red clover with 3 nutritious equivalents o\ 



nutritious equivalent of 

 potatoes : 



1X1:6 



1: 6 



1X1:9-00=3:27 



4 : 33 or 1 : 8 25. 



To produce this mixture, we feed them by giving them 9'7 lbs. of 

 dried clover for every 123*6 lbs* of potatoes.
