6th. The general relations of Zoology and Animal 

 Physiology. 



a. To breeds of domestic animals, and to the preserva- 

 tion of their purity. 



6. To the rearing, feeding and general tending of stock. 



c. To the agency of animal Hfe in fertilizing the soil. 



d. To the attacks of insects upon our cultivated crops — or 



7th. The general indications of Chemistry — such as 



a. That a fertile soil, in addition to various organic com- 

 pounds, contains at least eleven different mineral substances. 



b. That plants contain, usually, or in most of their parts, 

 the greater number of the same mineral substances. 



c. That the animal, as a whole, also contains them, but 

 distributed throughout its several parts in a manner dif- 

 ferent from that in which they are found, either in the plant 

 or in the soil. 



d. That the plant standing, as it were, between the soil 

 and the animal prepares for the latter both its organic and 

 its mineral food. 



e. That an intimate and beautiful relation exists between 

 the soil, the plant and the animal — or between the living 

 and the dead things of nature — or 



8th. The general indications of Geology and Chemistry 

 conjoined — such as 



a. That certain Geological formations are especially rich 

 in some of the mineral substances found in and required 

 by plants, and produce soils which with special treatment 

 will prove fertile and profitable to the cultivator. 



h. That others are especially defective in some of these 

 substances, and form soils which are naturally unproductive. 



c. That some abound in all the kinds of mineral matter 

 which plants require, and yet yield soils which are natu- 

 rally unfertile.
