from a handkerchief. In two minutes she was insensible, when I 
extracted two teeth ; in three minutes she recovered consciousness, 
and left my surgery perfectly well. The second was a gentleman, 
twenty-seven years of age, who inhaled from a piece of sponge 
containing 100 drops of chloroform. In three minutes insensibility 
was produced ; a tooth was then extracted, and he recovered in 
four minutes. The third case was that of a young lady who re- 
quired three teeth and four stumps extracted. She became insensi- 
ble in four minutes by inhaling the vapour from a handkerchief : as 
in the first case, the teeth and stumps were removed, and she re- 
covered in seven minutes after the operation. The great superi- 
ority of this new agent over ether is, that less is required to produce 
insensibility, it is more rapid in its effects, unconsciousness does 
not continue so long after the operation, the flavour is more agree- 
able to the patient, and leaves no unpleasant odour after inhala- 
tion, neither is that debility felt so often experienced after inhaling 
ether.

Nov. 19/A. — An unusually large meeting of medical men and stu- 
dents took place in the operative theatre of King’s College Hospi- 
tal, to witness three severe surgical operations performed by Pro- 
fessor Fergusson, while under the influence of the new prepara- 
tion. The chloroform was administered by Mr. Robinson, dentist, 
who had been furnished with this compound by Mr. Hooper, the 
eminent chemist of Pall Mall. The results attending the inhala- 
tion of this preparation were most complete, and satisfactory to all 
present. One of the cases was, for melanosis , the removal of the 
eye from the socket altogether. Another was fistula lachrymalis , 
a very painful operation of the eye. The third was a case of 
hydrocele, in which iodine was injected.
