(4) Gayet's Carbon Bisulphide Mtidiim'. \ method proposed by 

 M. Gayet, engineer to Mr. J. (\. .loannides' giunei-y at Tanf 

 of a combination of the principles involved in all the thre 

 machines. The inventor proposed to have a fumigation chan 

 similar to the American one, and after it had been charged \\ith 

 and the air :ed from it, it was to be connected with an iron 



retort containing charcoal, on t> which sulphur could be dropped 

 through a broad alve, the retort being kept red-hot in a fun

M. (lavet fitted up a small experimental apparatus taking about 

 one ardeli of seed and got perfectly satisfactory results with it. It is 

 possible that on th.' la rue scale coiidensafion ell'ects such as \\cre 

 obtained with Mosseri's machine might interfere with the results, 

 but carbon bisulphide does not seem to be absorbed by cotton 

 in the same way as hydroc-. and the fact that there wa> 



no difficulty in getting a free circulation of the vapour in the Ministry's 

 machine, would indicate that the probabilities of difficulty from this 

 source are n >i However. the objections to the machine are 



the same as the objections to t lie Ministry's machine. nameh . the 

 poisonous and inflammable qualities of carbon bisulphide. The 

 separate production of each dose on the spot reduces these objections 

 to a, minimum by avoiding the necessity of keeping any stoi 

 carbon bisulphide, and as ar. its could be made for washing 



the carbon bisulphide out of the seed with a, current of air before 

 opening the fumigation chamber, the danger, either of poisoning or of 

 explosions, should be very small -indeed. However, before erecting 

 a machine on these lines it would certainly be wise ; :tain the 



opinion of the insurance societies and of the Department of Public 



Health.
