equivalent for a certain amount of food. The more warmly 

 we are clothed, the less food is required, because the loss of 

 heat by cooling, and consequently the amount of heat to be 

 supplied by food, is diminished. The cooling of the body 

 increases the amount of food necessary. ''If we were to 

 " go naked, like certain savage tribes, or if in hunting or 

 " fishing we were exposed to the same degree of cold as the 

 " Samoyedes, we should be able with ease to consume lOlb. 

 " of flesh, and perhaps a dozen of tallow candles into the 

 " bargain, daily, as warmly clad travellers have related with 

 " astonishment of these people. We should then be able to 

 " take the same quantity of brandy or train oil without bad 

 " effects, because the carbon and hydrogen of these sub- 

 " stances would only suffice to keep up the equilibrium 

 " between the external temperature and that of our bodies." 

 (poffe 22.) 



A want of warmth, then, is tantamount to a waste of food, 

 and if we apply this to the want of shelter to our sheep while 

 feeding upon turnips in the winter season, when the temper- 

 ature of the nights is frequently below the freezing point of 

 water, and this over 3,000,000 acres of turnips in the king- 

 dom, we shall find the loss of food very great indeed. Mr. 

 Childers, of Cantley, and Mr. H. S. Thompson, of Kirby, 

 have upon a small scale fed sheep in sheds during the winter, 

 and the former says that the sheep in sheds consume nearly 

 one-fifth less food, and make one-third greater progress than 

 those fed with the very same food in the open field ; or very 

 nearly the same food will feed double the number of sheep. 

 And a farmer in the Doncaster Chronicle, February 4, 1842, 

 states that 1,760 bushels, or about 44 tons of turnips, kept 

 him in a warm yard 200 sheep (Tegs) well for five months, 

 while it would have required ten times that quantity out of 

 doors. Mr. Morton informed Professor Playfair, that 200 

 sheep in the open field eat 24lbs. each of Swede turnips daily,
