EFFECT OF HYDROGEN GAS ON THE VOICE. 



The Journal Britannique, publiflied at Geneva by Prevot, 

 contains the following article : — " Maunoir was one day 

 amuiing hinifcif with Paul at Geneva, in breathing pure 

 hydrogen air. He infpircd it with eafe; and did not per- 

 ceive that it had any fenfible effe£l on him, either in enter- 

 ing his lungs, or paffing out. But after he had taken in a, 

 very large 4ofe, he was defirous of fpeaking, and was afto- 

 nifliingly furpriied at the found of his voice, which was be- 

 come foft, flirill, and even fqueaking, fo as to alarm him. Pau^ 

 made the fame expermicnt on himfelf, and the fame effect 

 was produced. I do not know whether any thing fimilar 

 has occurred in breathing any of the other gafes." 



pHEAP METHOD OP PREVENTING THE DISAGREE- 

 ABLE SMELL OF PRIVIES. 



In fome honfes, privies, when badly placed and ill taken 

 care of, diBlifc an odour as inconvenient as unhealthful 5 but 

 ^he means of remedying this evil is exceedingly eafy. If a 

 certain quantity of milk of lime (water in which lime has. 

 been diffulved, and whitened by the fine particles of that 

 fubftance) be mixed with a ley of aflies, or foapy water that 

 has been even ufed fox wafliing, be thrown into the fink of the 

 privy, it will deftroy the offenfive fmell. By thefe means, 

 for the value of a few pence, any colleftion of filth whatever 

 may be neutralifed. By the fame procefs conveniencies for 

 fick perfons may be kept in their apartments. Nothing is 

 neceflary but to have a tub covered with a board as a feat ; 

 jpve or fix pounds of quicklime, a fmall quantity of aflies, 

 and two buckets of water thrown into the tub, will prevent 

 any difagreeablc odour. It may readily be conceived that 

 the (ame procefs may be employed in regard to a night- 

 9 chair.
