the nervous system. Mr. Lawrence gives an account of one which he 
characterizes as “one of the most painful surgical operations,’’—and 
which consisted in extirpating the eye-ball for the cure of -malignant 
di . This was performed with so little pain, that the patient, after 
recovering from the effects of the ether, did not even know that the 
operation had commenced. 
At the same time that the success of this application has been far 
greater than could have been anticipated, there have, however, been 
tain 24 cubic inches of ether; but the same quantity of air at 70° con- 
tains 49 cubic inches of the same. This demands attention: but the 
proper temperature of the room for the best success may be easily as- 
opposite nature. A fourth point demanding caution, arises 
peculiarly inflammable nature of etherous vapor. Should this agent 
be employed by careless persons during candle light, it may, from 
its highly inflammable nature, explode; and from the consequences 
of that explosion it does not appear evident that the person breathing 
the vapor would escape—although we have heard of no accident of 
this kind at present. . 
The effect of the vapor of ether upon the system seems to be the 
same as that of an overpowering quantity of alcohol; and asa proof

and this has probably been owing to the quantities of the vapor inha- 
led. ‘Thus, in several cases the effect has been to deprive the patients
