viii PEEFACE 



Animals. Messrs. Barford and Perkins, Peterboro', and 

 Messrs. Eiehmond and Chandle, Manchester, have obligingly 

 furnished the figures of Food-preparing Machinery. Dr. 

 Fream has been good enough to supply all the figures 

 illustrating the Artificial Grasses, while the Editors of the 

 Journal of the Royal Agricultural Society and Transactions 

 of the Highland and Agricultural Society of Scotland have 

 lent the blocks illustrating some of the Parasitic and other 

 Flies, the Yew Tree, and Cowsheds.
