Experiment No. 22. 
September 1st.—A middling-sized Dog. Normal tempera¬ 
ture 102°T. 7.53 a.m.— Injected. 8.5 a.m.— Temperature 
102° 2 ; the breathing is becoming affected, and the Dog is 
uneasy. 8.15 a.m.— Temperature 102°’4. 8.30 a.m.— Tempera¬ 
ture 101°'5. 8.45 a.m. —Temperature 101°'6. 9 a.m.— Tem¬ 
perature 101 o, 8. 9.35 a.m. —Temperature ]01° G. 10 a.m. — 
Temperature 101 o- 5. 10.20 a.m. -— Temperature 101 o, 4. 
10.45 a.m.— Heart beating, 132; pupils natural; respirations 
40 ; first convulsive movement evident. Pupils have become 
quite widely dilated, and the conjunctiva; pitted as it were. 
This is an invariable symptom. Temperature 101°'7. 10.50 
a.m. —Pupils widely dilated ; convulsions very strong. Com¬ 
menced artificial respiration (two hours and fifty-seven minutes 
after the injection of the poison) ; the convulsions at 
once ceased. 11 a.m. — Temperature 101 o- 5 ; prd se 200, 
strong and regular ; respirations 44 ; universal convulsions in 
response to galvanism. 1 p.m. —Temperature 101°‘2 ; respira¬ 
tions 40; pulse 200 ; galvanism, universal convulsions, micturi¬ 
tion, and defecation ; universal convulsions on the application 
of cold water to the head. It is somewhat remarkable that 
there are still convulsive movements, even when the battery is 
not applied. 2.35 p.m.— Slight convulsive movements, the 
tongue is protruded and retracted very rapidly in response to 
faradization. 4 p.m.— Temperature 101 O- 2 ; pulse over 200; 
respirations 44. The same response to faradization, but at 
first there was no response to the negative electricity, but after¬ 
wards there was more response to the negative than to the 
positive. Response also to galvanism, and the convulsions 
are much more violent from this than from faradization. G p.m. 
—Temperature 102°; pulse 200; respirations 44. 8 p.m.— 
Temperature 101 o, 2. 8.10 p.m. —Heart ceased to beat in nine 
hours and twenty minutes.

very feeble ; respirations 44; no response to galvanism or fara¬ 
dization. 7.30 p.m. —Heart ceased to beat in nine hours and 
twenty-five minutes.
