A, (fig. z.) the body of the water-wheel, which is hollow 

 in the torm of a drum, and is fo conltru&ed as to be proof 

 againft the admiffion or water within it. 



B, the axis on which it turns. 



C, the float boards, placed on the periphery of the wheel. 

 Each board is obliquely fixed firm to the rim of it, and to the 

 body of the drum. 



D, the refervoir, containing the water. 



K, the penftock, which regulates the quantity of water 

 running to the wheel. 



F, the current of water which has palled the wheel. 



Fig. 3 is a front view of the water-wheel, fhowingnhe 

 oblique direction in which the float-boards, C, are placed on 

 the face of the wheel.

H E concordance of a variety of facts feems to render it 

 molt indifputable, that certain ftony and metalline fubftances 

 have, at different periods, fallen on the earth. Whence 

 their origin, or whence thev came, is yet, in my judgment, 

 involved in complete obfeurity. 



The accounts of thefe peculiar fubftances, in the early 

 annals, even of the Royal Society, have unfortunately been 

 blended with relations which we now confider as fabulous 5 

 and the more antient hiftories of (tones fallen from heaven, 

 from Jupiter, or from the clouds, have evidently con- 

 founded fuch fubftances with what have been termed ce~ 

 vaunia, hattUia 9 omkrta, brontia, &c. names altogether un- 

 appropriate to fubftances fallen on our globe. Indeed foma 

 niiflead, and others are inexpreffive. 



The term ccraunia, by a mifnomer, deduced from its fup- 

 pofed origin, feems, as well as boetilia f, to have been an*
