On the Gaacous Oxide vf Azote. 217 



Ti-^ccts of the Gaseous Oxide of Azote nhen introduced into 

 the Lji/igs hy Respiration. 

 All those who have tasted or inhaled this gas agree that 

 it has a ta<te strongly saccharine, the impression of which 

 has been often retained during the whole day. I myself 

 experienced also a nitric taste (in tnith, it was the gas lat- 

 terly produced which I tasted). M. de M said, iia 



doubt upon perceiving the same taste, that there was some- 

 thing styptic in it. The rest did not perceive any thing else 

 than" a saccharine taste ; which is certainly a very decisive 

 one, considering the small quantity of matter which the gas 

 could contain. 



The foUowincr is a precise account of the different effects 

 of the gas, as they were successivelv experienced by the va- 

 rious gentlemen who inhaled it. The gas was inhaled by 

 nieans of a bladder with a stop-tock, the nostrils being held 

 close, and the lungs emptied as much as possible. 



M. G suddenly lost all recollection at the third in- 

 halation : he continued it for iive minutes ; after which he 

 returned to his senses very much fatigued, without being 

 able to recollect any ether sensation than a sudden fainting, 

 and a tingling in the temples. 



M. de M experienced a saccharine and styptic taste, 



a great dilatation, accompanied with a heat in the breast j 

 his veins were swelled, and his pulse fell. Every object 

 appeared to dance round before his eyes. He thought, how- 

 ever, that he could have supported a stronger dose. The 

 bladder was not large enough for his lungs, 



]\/[, de P experienced a saccharine taste at the first 



inhalation, which became afterwards imperceptible. His 

 liin<rs were strongly dilated, and with great heat. He ex- 

 perjenced very agreeable sensations .after laying aside the 

 bladder, and he fell into involuntary til^ of laughter. 



]V], tie S experienced the same saccharine taste as the 



former gentlemen, and the impression of it continued from 

 ten o'clock in the morning until past midnight; he also ex- 

 perienced vertigoes, and his legs remained benumbed all day.
