bladder would be able, or, if able, would have resolution, to 

 conduct such a process as that described by Mr. Goring. 



Such a proceeding might be adopted in some living brute 

 animal, if one were found with a calculus in the urinary 

 bladder, for the sake of manifesting the power and effects of 

 galvanism : but 1 cannot conceive that any circiou^tance or con- 

 dition can authorise such a practice on the living human body.*

This volume contains the following papers : — 



1. A Synop'ic Scale of Chemical Equivalents. By William 

 Hyde VVollaston, M.D. Sec. R.S. — A full account of this impor- 

 tant instrument has been given in the 21st number of the Annals, 

 to which therefore the reader is referred. 



2. Method of clearing Equations of Quadratic, Cubic, Quadralo- 

 Cubic, and higher Surds. By William Allman, M.D. — This 

 method, which is very ingenious and simple (if such a term can he 

 applied to the resolution of equations involving the higher powers), 

 originated, it appears, with Dr. Mooney, Follow of Trinity College, 

 Dublin. It applies universally till we come to equations of the 

 11th power. Such methods are of considerable importance, by the 

 tendency which they have to throw additional light upon the nature 

 of equations ; though I doubt whether they would be found conve- 

 nient enough for use in practical cases. 



3. Analysis of a New Species of Copper Ore. By Thomas 

 Thomson, M.D. F. R.S. L. and E. — This ore was brought from 

 the Mysore by Dr. Heyne, where, from his account, it seems to 

 exist in prodigious quantities, chiefly in nests in primitive rocks. 

 This ore has a brown colour, a conchoidal fracture, is soft, sectile, 

 and of the specih'c gravity 2 620. It is an anhydrous carbonate of 

 copper, mixed with red oxide of iron. Its constituents were found 

 as follows : — 



• la justice to .Mr. Goring, I think it proper to state that I received a letter 

 from hint, dated Nov. 5, requesting me not to p ii bl i-.li his proposal. My 

 opinion of the propft.nl via-' I lie same as that of Air. Armiter, ami indeed of 

 <\'iy medical man, that it was quite Impracticable. I published it because 



I wak conscion* that the proposal could do nn harm, as it was not ratceptible 



of being tried. I conceive. I that Mi. (inline; himself would i mined i.itch be 

 common! ol ii- impracticability when hi- MM) it in print. The small space 

 •bat il occupied in the Annatt rendered it in every respect innocent.
