" nutrition of the animal is arrested ; and when they are 

 " present, the graminivorous animal obtains in its food the 

 " very same principle^ on the presence of which the nutri- 

 tion of carnivora entirely depends." 



To apply these discoveries to our present mode of feeding 

 sheep on turnips. — According to Dr. Daubeney's table in his 

 valuable paper " On the application of Science to Agricul- 

 ture," turnips contain in about 50 tons, or 100,000 lbs. weight, 



99.274 lbs. water and carbon. 

 .556 fixed ingredients. 

 .170 azote. 



100.000 lbs. 



Now 25 tons, being an average weight for one acre of land, 

 will only contain 85 lbs. of nitrogen ; hence we may see the 

 necessity of adding grain, as practised by Mr. Childers and 

 Mr. Thompson. The former states that sheep fed with the 

 addition of half-a-pint of barley per sheep per day, J lb. of 

 linseed cake, a little hay, and with a constant supply of salt, 

 become ready for the butcher in ten weeks, with a gain of flesh 

 and tallow of from 33 lbs. to 40 lbs. per head : (one sheep 

 gained 55 lbs. in twelve weeks:) and that with artificial food, 

 30 tons of turnips will feed 60 sheep : — ( Journal of the Royal 

 Agricultural Society, vol, 1, part IV, p. 409 ) — while on the 

 usual plan of feeding on turnips alone out of doors, the average 

 of the country is, that 20 tons of turnips will feed in sixteen 

 weeks 10 sheep, with a gain of only 20 lbs. of flesh and tal- 

 low. The barley and cake cost 6d. to lOd. per week for each 

 sheep, and the turnips with this addition thus go eight times 

 as far, or produce eight times the amount of flesh and tallow,^ 

 The practice of Belgium is also in strict conformity with the 

 principles here laid down by Professor Liebig; for not only 



* The turnips alone go four times as far, for 30 tons feed sixty sheep, while 

 on the usual plan of feeding they would only feed fifteen sheep : but the same 

 weight of turnips with artificial food produce also very near double the amount of 

 flesh and tallow, and, therefore, go eight times as far.
