I have frequently repeated the experiment of placing a portion of 

 thefe globules of meal, no larger than a grain of fand, upon a clean 

 glafs ; and, after pouring a drop of water on them, brought it to the 

 fire. After the water and globules Vv'ere heated, and the moifture was 

 evaporated, the globules allumed a flat fliape, very like that of cakes, 

 ^vhich is reprefented in fig. 17, STVW. Mofi: of thefe had a little ri- 

 fing in the middle, being the place, as I before mentioned, where, in 

 my judgment, they were fupplied with juices in their growth. And I 

 have often feen the very fmalleft of the globules undergo the 

 fame alteration in their fliape as the larger ones. In thefe obferva- 

 tions I found a portion of meal, no larger than a grain of fand, mixed 

 with a fmall drop of water, fully fufficient to exhibit the change of 

 fliape before noted ; for, if more of the meal is ufed, the particles lie fo 

 confufedly heaped on one another, that they cannot be diftinftly feen, 

 and, it is fcarcely to be conceived, that a portion of meal, no larger 

 than a grain of fand, fliould confifl of fo many particles as are pic- 

 tured m fig. 17. 



I have often examined a fmall ])iece of bread, taken from a loaf 

 made of fine flour, after the hufk or bran had been taken from it. 

 The particles of meal in this fmall piece of bread, appeared very much 

 like thofe reprefented mfig. 17, with this difference only, that the 

 particles in the bread, lay much more irregularly, and appeared more 

 mis-fliapen, Vvith ragged points and rifmgs; a true reprefentation of 

 all which is to be feen at fg. 18, A B C D E.
