becaufe there was very little difference between thofe in the Rye 

 and in the Wheat, except that thofe in Rye were much fmaller. 



I alfo examined the feeds of Barley, and took from thence the 

 young plant with its leaves. But becaufe I perceived very little 

 difference between them and thofe in the grains of Wheat and Rye, 

 I did not think it neceffary to give drawings of them. 



But what is worthy of remark in Barley is, that in every grain 

 there are to be feen the rudiments or beginnings of five dillind 

 plants, therefore I have caufed a drawing to be made of them, as 

 they appear at one cutting of the feed tranfverfely. 



Fig. 24, A B C D E F G, is a fmall piece of a grain of Barley cut 

 tranfverfely near the end of the feed, where the origin of the young 

 plant is formed, in which may very plainly be feen, a tranfverfe 

 fedion of five feveral particles of an oval fliape, in each of 

 which, the veffels compofmg them may be diftinguiflied. The 

 reafon why thefe young beginnings of plants appear oval and not 

 perfeAly round, I take to arife from the evaporation of the moif- 

 ture, as well in the plants, as in the mealy fubliance furrounding 

 them ; for we mull: confider, that the external part of the feed in 

 drying will contrad itfelf, and that when it is afterwards moiftened 

 with water, it will, in a Ihort time, again extend itfelf, and then 

 the plants, inllead of an oval, will affume a round figure. 



Thefe young plants are placed in a very fmall quantity of mealy 

 fubftance of a darker colour, and not compofed of fuch tranfparent 

 globules as the reft of the meal of which the Barley confifts. This 

 dark meal is placed between G A B C D E, iind betw een E F G is 

 the mealy part, which for the moft part compofes the fubfi:ance of_ 

 the Barley ; and though this dark mealy fubliance may here feem 

 to be in great abundance, yet it mull be obferved, that this does 

 not extend farther in the Barley, rifing no higher, (in a Hoping di- 

 redion), than where the young plants extend. 



I afterwards examined Oats, and found that each feed contained 

 in it the beginning, or firft rudiments, of young plants, and the be-
