Chap.. XIV. Vf Change of Specie s. 227 



Yet Plants feem to be better fecured by the Salu- 

 brity and Simplicity of their Food, than Animals are 

 by their Senfes : To compenfate that Inequality of 

 Danger-, Animals have Pleafure from their Senfes, 

 except fome miferable Animals (and fuch there are) 

 that have more Pain than Pleafure from them. But 

 I fuppofe, more Animals than Plants are poifon'd ; 

 and that a poifonous Animal is lefs fatal to a Plant, 

 than a poiionous Plant is to an Animal. 



It being fufficientiy proved, that every fort of Ve- 

 getables, growing in the fame Soil, takes, and is nou- 

 rifhed, by the fame Sort of Food ; it follows from 

 hence, that the beneficial Change of Sorts of Seeds 

 or Plants, we fee in the common Hufbandry, is not 

 from t\\Q Quality of the Sorts of Food, but from other 

 Caufes ; fuch as, 



I. Quantity of the Food. 

 II. Conftitution of the Plants* 

 III. Quantity of the "Tillage. 



In Dr. Woodward's Cafe, upon his Hypothefis, the 

 Three Proportions of Seeds, viz. Barley, Oats, and 

 Peafe, might be fown all together in the fame Acre 

 of Ground, the fame Year, and make Three as good 

 Crops as if fown fingly in Three fucceffive Years, 

 and his Two Crops of Wheat in one Year likewife. 

 But every Farmer can tell, that thefe Three Propor- 

 tions of Seed would not yield half the Crop together, 

 as one would do fmgle ; and would fcarce produce 

 more than to mew what Grains were fown, and which, 

 of the Sorts were the ilrongefl, and the mod able 

 Robber. 



Though this Failure would, in Truth, be from no 

 other Caufe than want of the fufticient Quantity of 

 Food, which thoie Three Crops required ; yet, per- 

 haps, the Doctor might think, that all Three Crops 

 might fucceed together very well, taking each its 

 proper Nourifhment, were it not for want of Room, 

 Air, and Sun.
