82 Animadversions on Mr. Genet's Memorial, fyc. 



termination will be witnessed, in the Commercial Emporium , 

 should its citizens be induced to become " associates for the 

 essay of an hydronaut." 



I am aware that in every controversy carried on in a Jour- 

 nal, it is necessary to be as brief as the merits of the subject 

 will allow ; I will therefore, at once proceed to notice some of 

 the observations of Mr. Genet in his last ' Reply,' and will 

 afterwards attempt a short analysis of the principal projects 

 brought forward in the ' Memorial,' which has given rise to 

 this disquisition. In doing this, I shall, without an effort, 

 avoid garbling and misrepresentation, and should I call the 

 " submissive philosophy" of Mr. Genet into action, it will 

 neither merit, nor receive my sneers ; for, although he may 

 identify himself with his schemes, I shall carefully separate the 

 two ; and, indeed, were it not for the respectability of the 

 former, the latter would not have received any public notice 

 from me, however they might have answered for the amuse- 

 ment of an idle hour. 



The claims of Mr. Genet, to the important discovery of ap- 

 plying the " Upward Forces of Fluids" as a motive power, in 

 propelling machinery, and to various other useful purposes, 

 have been made known to a very considerable extent, by his 

 friend Dr. Pascalis, in Vol. XI, at page 339, of your Journal ; to 

 this article, with the accompanying plates, I must refer those 

 of your readers who do not possess the Memorial itself; as 

 with the aid of the quotations which I may make from the 

 latter, the merits of the controversy will be readily ascer- 

 tained. 



In page 212, 213 of your last number, Mr. Genet has quo- 

 ted from the Franklin Journal, my animadversions on his de- 

 scription of the vis motrix of the steam engine, and proceeds, 

 through two or three pages next succeeding, to state the great 

 amount of information on this subject which, in the year 1 784, 

 he derived from conversation with its great improver, Mr. 

 Watt, "all which," he says, "is perfectly present to my 

 memory, my mental retentive faculties being preserved, by 

 the invigorating exercise of a laborious country life." It must 

 be confessed that the extent of information which he displays, 

 accords with his own history of its attainment, and does great 

 credit to a reccollection of between forty aud fifty years 

 standing; the very reverse of credit, however, would be due 

 to a man who professed to have obtained his knowledge of the 

 engine in the ordinary way, from books, and observation..
