conies more predominant. Be this as it will, the apparatus 

 may some day serve to ascertam the fact, since the spirit con- 

 densed by its means is strongly impregnated with that princi- 

 ple, and, if resinous, may be easily separated by simply mixing 

 it with pure water ; when the spirit, by having a greater affi- 

 nity for the water, will disengage itself from, and allow the 

 resin to precipitate. 



To conclude : It may be observed that the most approved 

 wine is not always produced from the best must, but frequently 

 derives its superiority from fermentation and good manage- 

 ment. In like manner will beer and other fermented li(iuors 

 acquire their greatest perfection from the same sovu'ce, which, 

 for that reason, ought to claim and engross the attention of 

 every brewer, or other person engaged in the manufacture of 

 fermented liquors. 



The invention of Madame Gervais above described, is fur- 

 ther stated to have engaged the attention of several of the most 

 eminent chemists and enlightened men in France, where a 

 company has been formed, consisting of the Due of Bellune, 

 Count Chaptal, Viscount Chaptal, Count Dullau Dallemans, 

 Count de Brissac, Mons. Froidfond de Bellisle, Mons. Gaston 

 Deurbi'oucq, &c. &c., who have purchased Madame Gervais' 

 patent in order to propagate the utility of her improved method 

 of fermentation ; which, moreover, is already successfully prac- 

 tised at the considerable brewery of M. Chappellet in Paris. 



A patent fqr the use of the apparatus in this country has been 

 obtained by Messi's. Deurbroucq and Nichols ; and it has been 

 tried with such complete success by Messrs. Gray and Dacre 

 of Westham, in the county of Essex, that they have adopted 

 the system, and are now, as far as the alteration to be made 

 in their working-tuns will permit, fermenting on no other 

 plan. 



XI. A Defence of the Neiio Theory of the Tides, in reply to 

 Mr. Henry Russell's Observations. By Captain Forman. 



MR. RUSSELL has at length produced the principle upon 

 which his hypothesis is founded ; and, as I am now able 

 to meet him on equfl terms, I have no doubt of speedily con- 

 vincing your readers, that his theory (which by the way is as 

 great a deviation from the old one, for which he expresses so 

 much veneration, as mine is) is not sufficient to account for the 

 phenomenon in question, and consequently cannot possibly be 

 true. 



" Let a stick," he says, " of about an inch in diameter, be 

 loaded at each end with a steel ball, taking care that its spe-
