fin the memoir of M. le Marquis de Turgot on the different sorts of wheat 
(triticum) cultivated in some parts of Lower Normandy, he mentions that the 
stalks of several of the sorts are not hollow, : buVfilled with pith. ^ 
Royal Society of Agriculture at Paris , v. ii.—1785* 
The common Lammas wheat ( triticum hyhernum) is described as having four 
flowers in a calyx, bqt it rarely happens in England that there are more than two or 
three seeds or corns, which number is most desirable, for if more, the corn is small. 
Mr. Needham observed, that in the ripe pollen of every flower examined by the 
microscope, some vesicles are perceived from which a fluid had escaped ; and that 
those, which still retain it, explode if they are wetted, like an eolipile suddenly ex¬ 
posed to a strong heat. These observations have been verified by Spallanzani and 
others. Hence rainy seasons may make a scarcity of grain, by bursting the pollen 
of the flower of corn, before it arrives at the stigma of the flower. Botanic Garden . 
If wheat is long masticated, or a little of the flour jnade into a paste with water, 
and then washed with the hands under water, which must be frequently changed, 
till it is no longer discoloured, that is, till the mucilage and starch are washed fiom 
it, then what remains is called the gluten , which i$ indissoluble in either hot or 
cold water, and if the corn be good, is elastic, and will contract itself when drawn 
out; but if the corn hath begun to heat, it is brittle ; and if the corn hath fer¬ 
mented, none of the gluten will be obtained, and the corn is then bad, and will 
not grow* Phytologta .
