57. Upon the Application of Hot Water in heating Hot-houses. 

 By Mr. Thomas Tredgold. Read August 5. 1828. 



This is by far the most valuable paper which has ever 

 been published on the subject of hot water, and we shall 

 therefore give it neai'ly entire, with most of its tables, and with 

 copies of its engravings. We shall only make one remark ; 

 and that is, on the expression which Mr. Tredgold uses, of 

 Mr. W. Atkinson being "its discoverer." Mr. Tredgold 

 wrote a paper to the same effect, dated January, 1827, 

 which appeared in the Garde?ier's Magazine, (Vol. III. 

 p, 427.) All that we have to state is, that, notwithstanding 

 Mr. Atkinson's discovery, which we do not in the slightest 

 degree doubt, since it is no uncommon thing for two persons 

 to discover the same thing, it is an imdeniable fact that the 

 first discoverer was Bonnemain ; and that Chabannes heated 

 both dwelling-houses and hot-houses by hot water in London 

 and its neighbourhood in 1816, some years before Mr. At- 

 kinson's discovery, which was in 1822. The proofs will be 

 found in the third and fourth volumes of the Gardener's 

 Magazine. We are not sui-prised that Mr. Atkinson should 

 not have heard of what Chabannes had done ; for we have 

 learned, from what we consider undoubted authority, that 

 when, in January last, some of the Bank of England directors! 

 proposed to heat a part of their establishment by hot water, 

 their architect, eminent though he is, had not heard of such 

 a mode of heating. 



The fact is, that, in this progressive age, a man who has 

 the means of existence to procure by his labour or his talent 

 ought to be learning every day of his life. If he stands still 

 for a moment, the world will march on without him. Before
