Safe Anesthesia . 
[February, 
abscess pointed towards the outer aspedl of the thigh, while 
another was more in front. The opening of the first was the 
special operation at this time. The notes record that, before 
administration of the anaesthetic, the pulse was 134. At 
9.47 the anaesthetic was given, and at 9.50 the pulse had 
fallen to 120 ; at 9.54 it was 100, and at 9.55 anaesthesia and 
muscular relaxation were complete. At 9.56J, there was 
vomiting, which was undoubtedly caused by the patient 
having had food in the morning, contrary to orders. The 
operation was over at 10.1, and at 10.3 the patient was re- 
covering. At 10. 5^-, she was able to answer intelligently. 
The amount used was three drachms and a half. 
Case III. was a girl aged eight. The operation was re- 
moval of the forefinger for strumous disease of bone. At the 
beginning the pulse was 120 ; in one minute and a half, it 
had fallen to no ; in two and a half, to 105 ; in five, to 102 ; 
in six and a half, to 100 ; and in seven minutes anaesthesia 
was complete. At eight minutes and a half from the time 
the anaesthetic was given, the breathing became slightly 
stertorous. At the end of fourteen minutes, the operation 
was over, and the pulse was 105. The patient recovered 
from the anaesthetic, so as to answer questions, in about two 
minutes, and there was no headache, sickness, or vomiting 
afterwards. 
Case IV. was the same patient as in No. 2. The abscess 
in front of the thigh previously alluded to was opened. At 
9.9 a.m., before the anaesthetic was given, the pulse was 140 ; 
at 9.10J, it had fallen to no ; at 9.12, it was at 104 ; at 9.13, 
there was slight flushing of the face ; at 9.14, the pulse was 
100, and there was slight stertor; and at 9.15 there was 
complete relaxation and absence of reflex movements. The 
operation was quickly over; at 9.22, the pulse was no; at 
9.23, consciousness had returned ; and at 9.24, the pulse had 
risen to 130. The amount used was four drachms. 
Case V. was that of a very powerful young man, aged 
twenty-one, who was operated upon for the radical cure of 
inguinal hernia. Immediately before giving the ansesthetic, 
the pulse was very rapid from excitement — about 140. At 
9.17, the anaesthetic was given; at 9.18J, the pulse had 
fallen to no ; at 9.22, pulse no and slight struggling; at 
9.23, it was observed that the face was slightly flushed; at 
9.24 and 9.26, considerable struggling ; at 9.28 the pulse had 
fallen to 74, and the operation was commenced ; at 9.35, 
pulse 70, and respirations deep and regular; at 9.40, the 
operation was over, and at 9.42 consciousness returned. 
About 9.41, there was deep anaesthesia and complete
