i,'JS On the Gaseous Oxide of Azote. 



M. G , the same saccharine taste. After laying as^ide 



the bladder he experienced a dimness of sight, and after- 

 wards a very pleasant sensation, which spread through his 

 whole body. His legs were benumbed. 



M. de C— , a saccharine taste during the whole day, 



tingling in his ears, legs benumbed, the stomach almost 

 choked up. Upon the whole, he regarded what he had 

 experienced as more painful than agreeable. 



F^xperiment, 



I was anxious to know in what degree the necessary con- 

 straint of breathing in a bladder influenced the above results. 

 These gentlemen, at my request, put themselves to the trouble 

 of breathing common air in the same manner. They only 

 found themselves mechanically fatigued j and all of them 

 agreed in the same results. 



Another Experiment. 

 I was also anxious to try the effect of oxygen gas. Those 

 who inhaled it assured me that they experienced little differ- 

 ence between it and common air, which consisted solely of 

 an augmentation of heat in the lunfjs. 



Conclusion. 

 Thus the singular effects above described belong to the 

 gaseous oxide of azote alone. 



Second Meeting. 



The object of our second meeting was to repeat more at 

 large the experiments relative to the respirability of the 

 gaseous oxide of azote. 



We put into a retort about eight hectogrammes (nearly 

 16 ounces) of the nitrate of ammonia prepared as at first j a 

 lengthening tube was adapted to a bottle with two necks, 

 whence, by means of a tube of Welther, the gas proceeds 

 into the tub. The retort rested on a sand-bath. 



Upon the first application of the heat the salt melted, and 

 almost at the same time some reddish vapours were formed 

 in the retort, hut in very small quantity. The air of the 



vessels
