from the mouth. The convulsions gradually sub- 

 sided ; in a few minutes I withdrew the chloroform, 

 but the convulsions quickly returned, and the chloro- 

 form was as immediately reapplied. The result was 

 that I kept the child continually under the influence 

 of the chloroform excepting partial relaxation of it 

 at intervals, to admit of the administration of a little 

 milk, drawn artificially from a wet nurse who was in 

 attendance. We continued this treatment from 

 December I9th to the 28th of the same month. The 

 result was a perfect success ; the child had inhaled 

 twelve fluid ounces of chloroform. 



Some years later I had a still more remarkable 

 case of the same kind, but on this occasion we had 

 to continue the operations for three weeks, the 

 child inhaling nineteen fluid ounces of chloro- 

 form. The method was as successful as before. 

 The conclusions at which I arrived, after treating a 

 number of similar cases in the same way were 

 (i) that to be successful the use of the chloroform 

 must be continuous, not intermittent ; (2) that no 

 artificial food should be given, but that a wet-nurse 

 should be employed from the commencement, 

 drawing the milk with a breast-pump and adminis- 

 tering it with a spoon. Whether this method has 

 been tried elsewhere, or whether newer fashions have 

 been proved better I do not know. 



In 1876 I commenced another series of investiga- 

 tions, which are still in progress. Several of our 

 geological authors have called attention to two facts ;
