of Great Britain. It is perhaps the most correct catalogue 

 which in our present imperfect knowledge of British ornithology 

 has been as yet compiled. But he has made (we do not know 

 on what authority) very considerable alterations in the old ar- 

 rangement, and composed a variety of new English generic 



names. 



A catalogue has likewise just issued from the press, entitled 

 Catalogiis Avium in Insnlis Britannicis habitanlium, curd et 

 studio Edivardi Forsieri jun. This is merely a catalogue of 

 birds discovered wild in Great Britain. Mr. Forster differs also 

 in this catalogue in his arrangement from the arrangement and 

 names of Linneus. He enumerates 293 species. 



Another new work On the jiernicious Influence of Wine and 

 fermented and spirituous Liquors in general, is about to be pub- 

 lished ; containing Preliminary observations on the principles of 

 health, and on the extensive application of the doctrine main- 

 tained by Mr. Abernethy (in part i. of his Surgical Observations 

 respecting the sympathetic influence of the digestive organs) to 

 the different genera and species of diseases; and on the periodi- 

 cal influence of atmospheric causes on owx health. 



Mr. J. Robertson, of Surry House Academy, Kennington Cross, 

 will in a few days publish A Practical Example Book on the Use 

 of Maps; containing problems and exercises to be worked and 

 filled up by students in geography. Designed as an auxiliary to 

 that study for the use of schools and private students. 



An interesting pamphlet " On the Accidents which occur in 

 the Mines of Cornwall, iii consequence of the premature Explo- 

 sion of Gunpowder in blasting Rocks, and on the Methods to be 

 adopted for preventing it, by John Ayrton Paris, M.D.F.L.S." 

 has just made its appearance. 



The same gentleman is now preparing for publication A De- 

 scriptive Catalogue of the Geological Specimens deposited in the 

 Museum of the Royal Geological Society of Cornwall ; inter- 

 spersed with observations tending to show the oeconomical ap- 

 plications of geology to the agricultural, mining, and connnercial 

 interests of the county of Cornwall. This work will form one 



volume octavo. 



To Mr. Til loch. 



Sir, — 1 beg the favour of correcting, through the medium of 

 the Philosophical Magazine, a typographical error in my Essay 

 on Galvanism recently published, which entirely destroys the 

 sense and force of the experiment, and which heretofore escaped 

 my attention. The passage, beginning page 277, line 2li, runs 



thus :
