fond of it. But as it frequently grows very rank, it is not 

 perfectly cured, and in a green state it moulds. If fed to a 

 horse in this condition, which is at all inclined to the heaves, 

 it will certainly produce it. 



As a nutriment, clover takes rank with the best of grasses. 

 According to Prof. Way, red clover contains, 



Water, 81.01 



Albumen, 4.27 



Fatty matters, 69 



Gum, starch, sugar, or heat-producing principles, . . . 8.45 



Woody fibre, 3.76 



Ash, 1.82 



Clover is a lime plant, but this element increases with its 

 age. In the young plant the proportion is much smaller than 

 in the old. Thus : 



OLD. TOTING. 



Silica,... 0.850 0.981 



Phosphates of lime, and magnesia, etc., 20.600 30.245 



Carbonate of lime, 30.950 7.642 



Magnesia, ; 3.930 2.285 



Potash, 25.930 33688 



Soda, 14.915 7.164 



Chlorine, 1.845 3.642 



Sulphuric acid, 0.495 6.723 



Carbonic acid, 5.744 



The upper part of the stem, with the leaves and heads, gave 

 a composition varying from the above, thus : 



Silica 0.810 



Phosphates, 21.900 



Carbonate of lime, 32.333 



Magnesia, 0.200 



Potash, 27.940 



Soda, 6.7S3 



Chlorine, 3.780 



Sulphuric acid, 3.366 



From the foregoing analysis it will be perceived that clover 

 differs in composition from the grasses. It contains only a
