28 On Meteoric Stones, 



hitherto been found to exist in human urinary concretions, at 

 any rate, in the large proportion it seems to be in this ; yet I 

 have some faint recollection of having heard or read of the same 

 thing having been noticed bv Vauqiielin (I believe). You must 

 pardon me if I am incorrect. 



Since I examined the above, I have received another portion ; 

 a more correct analysis of which I shall give you for insertion in 

 your next number. 



I remain, dear sir, 



Very truly yours,

IX. On Melewic Stones. By the Rev, T. Drummond. 

 To Mr, Tilloch. 



Sir, — Unwilling to trespass on your pages by a long letter. 

 I forbore to notice in my last, that it appears on the authority 

 of Pliny, that meteoric stones or aerolites were supposed to have 

 fallen from the body of the sun ; your pages record that some 

 modern philosophers have imagined them to have been projected 

 from the moon. I will not trouble you at this time with any 

 arguments in support of an opinion, that they are generated in 

 the regions between our earth and the nearest planets ; but since 

 I do not remember that any of your correspondents have no- 

 ticed the circumstance, I wish to mention that the same author 

 records a report that Anaxagoras Clazomenius had predicted 

 the fall of a meteoric stone, and that the prediction was verified. 

 [Lib. ii. c 58.] 



If, sir, we admit the report to have been correct, may we not 

 infer that astronomical calculations and a regard to planetary 

 influences must have led the philosopher to deduce his inference? 



If it be merely to gratify curiosity, I hope your readers in the 

 different parts of the civilized world will transmit to you an ac- 

 curate statement of the precise time in which the phaenomena 

 occur in future. Our pride in modern science must be hum- 

 bled by every indication of the attainments of the ancients^ unlebs^ 

 we can refute, or equal, or excel them. 



Yours respectfully, 



Noiwich, Gray Friars' Pnoiy, T. DrUMMOND.
