holding his nofe with his.left hand *.without power to take it 
away, though aware of the ludicroufnefs of his fituation—all 
his niufcles,feemed tobe thrown into*vibratory motion—he 
had a violent inclination to make antic ‘geftures—feemed 
Jighter than the atmofphere, and as if about to mount.  Be- 
fore the experiment, he was a good deal fatigued after a very 
long ride, of which he permanently loft iy fenfe.. Ina fe- 
cond.experiment nearly the fame efie&ts, but with lefs plea- 
tak In a third, much greater pleafure.” 
The cafes in which its effe€ts were prejudicial are alfo 
fiated with great candour. Thefe were of the hyfterical kind ; 
but the endearing of the whole of thefe phenomena led to 
a happy application of the gas to the cure of palfy, and of dif- 
eafes proceeding from a defeét of nervous energy; and feve- 
ral inftances of fuccefs are ftated, which are well Asaaving ® 
of attention. 
“We defire further,”’ fays the author, “ to try the effects. of 
our new agent in palfy,and in thevariouscafes of irwe deficiency 
of nervous power, which we have well learned to diflinguifh 
from cafes of relative defect of irritable power. As the limits 
of the efficacy of every remedy ought to be determined, we 
fhall not fhrink from any cafe, by rcafon of its inveteracy. We™ 
intend to oppofe our Nepenthe to the equable decay induced 
by time and intemperance.; and we hope to palliate fome of 
the evils of extreme old age itfelf. 
** We are emboldened by experience to pledge ourfelves for 
the fafe employment of the gas. .We fhall, indeed, be fadly 
difappointed if it do not fometimes prove the moft delicious 
of luxuries, as well as the moft falutary of remedies. In fay~ 
ing this, it may be allowed me to fuggeft to thofe, who have 
not attended to the tenor of my opinions, that I now for the 
firft time venture to hold forth thefe hopes. However ur- 
gently I may have recommended the invettigation, my lan- 
guage, with regard to its iffue, has always been, that I would 
not anfwer for the difcovery of a gafcous remedy in any denomi-~ 
nation whatever of difeafe. That natural or forced decay may 
be repaired, and the faculty of pleafurable fenfation renovated, 
* This was praétifed in all the experiments,
