but were not entered for competition, made by Wateel's process 

 for coDceDtrating at a low temperature, were exhibited res- 

 pectively by Mr. Langlois, of aTriolet, » aad Mr* Leclezio, of 

 (Grande Bale. » Messrs. Chapman and Barclay also forwarded 

 two samples which were in a like predicament. These were 

 of interest, as having been manufactured by Mr. T. Mottet, of 

 •1 Woodford, « in a Gadesden's pan. The principle of the lat- 

 ter is pretty much the same as that of the « Wetzel* — the dif- 

 ference being thai M. Motet's pan is heated over the naked fire, 

 wbereas the concentration is accomplished in the former by 

 means of the escape steam from a high pressure engine: an 

 economy, it is presumed, of fuel. A. a Rotators is used in 

 both cases for promoting evaporation. A patent for tbe ia- 

 troduction of a machine, somewhat on the same principle 

 as these, steam being the heating agent, was taken out in 

 France in 1830 by M. Milles Berry. It wiil be found descri- 

 bed at length in the Manuel du Fabricant et du Raffineur «ce Su- 

 cre, Paris 1841. 



3,— The Society's Third Gold Medal was awarded to the pro- 

 duce of that ingeDioHs invention, by which so much ma- 

 nual labour is avoided, the <(Batterie Gimart, » With the 

 application of steam as a heating medium, somewhat in 

 the manner adopted at aTUnion, » Mr. Daruty's, with 

 however, some modifications, this would appear the best, 

 and most economical system of evaporation yet proposed. 

 Messrs. W. Aikin and C» were the successful competitors, 

 with the sample from the uSotlisei Estate, managed by 

 Mr. Leathart. 

 4. — The Society's Fourth Medal, for the best sugar made in the 

 common pans, was, for the second lime, awanJed to Mr. 

 Arisiide Legentil, for tbe dWclmart sample, exhibited by 

 Mr. Brownrigg. It was in competition with several beau- 

 tiful samples, which manifested further progress again this 

 year in the nClairced Sugar »; and one of these, from 

 «Goodlands, * exhibited by Messrs. Hunter, Arbuthn«t and
