,if.„ opinion distinguishes .bis Instrument, is that the water 

 eerves instead of leathering or stuffing, so that .he fir.clio* 

 a„d consequent wear of one metalic substance against ano- 

 lh er is avoided. This Pump has no pis.on, but is romped 

 of two cylinders working one within .he other, and .t rs sup, 

 posed by the inventor to be capable of raising water 150 or 



200 feet. „ , 



A Committee consisting of Col. Lloyd, Dr. Perrot, and 

 Mr. Morris, was appointed to examine and report as to the 

 merits of .his invention. 



Pr Perrot, in presence of the meeting, compounded 

 the substance referred to by him at last meeting, and 

 prepared a Lamp with it. Although the experiment was 

 not successful in .bis instance, it cannot be doubted that a 

 similar ptepara.ion has perfectly succeeded elsewhere. If 

 this substance could be used in Mauritius as proposed, it 

 would afford a very advantageous mode of consuming the 

 Spirits produced in the Colony. On .bis account, the 

 thanks of .he Society were voted to Dr. Perrot. It 

 must, however, be taken into account, that the source of 

 a great proportion of the Revenue of this Colony would be 

 affected by this application of Spirits; for, if .be duties at 

 present leviable were exacted on Spirits used in Lamps, the 

 substance referred to could not be purchased at such a pr.ce 

 as would make the consumption of it, instead of oil, advaq- 

 tageous.
