formed are rather larger than any of the cells of the 

 three layers just described, the walls of which are per- 

 haps more delicate than any others in the entire kernel." 

 Directly beneath the cells of gluten, cZ, lies the albumi- 

 nous portion of the seed, which consists of hexagonal 

 prismatic cells, which are rilled with ovoid granules of 

 starch, shown at e. These granules of starch, f y are 

 enveloped in several layers of cellulose, or cell mem- 

 brane, which, when heated to excess in water, burst 

 and exude the starch contained in them. Gluten 

 affords large quantities of nitrogenous matter. 



Influence of Climate on Plants. 



A writer in the " Portland Press " gives some facts to 

 show that a northern climate, within certain limits, is 

 better adapted to those plants which yield food, than 

 the warmer climate, where the same plant is indigenous. 

 In order to succeed most satisfactorily, he thinks south- 

 ern plants must be carried to a latitude north of the 

 place where they grow. He writes : 



" That a northern climate is more conducive to 

 health than a southern one, is generally admitted ; but 

 that its influence upon the vegetable kingdom is more 

 propitious to the perfectability of plants necessary for 

 the sustenance of man and of beast, is a proposition 

 perhaps not so ^generally noticed and adopted as it 

 should be. In these cold northern regions we some- 

 times need to be apprised of facts which will rebuke 

 the spirit of discontent, and make us more reconciled

" The influence of climate upon plants is unquestion-
