THE T FT AH ATOP HIDIA OF INDIA. 
SO 
head about in an uneasy manner. 12.35.—Looks anxious and 
restless; leans hind-quarter against the wall; twitchings of 
nostrils. Eyes staring; tapetum lucidum shining brilliantly ; 
ears retracted; tail raised. 12.43.'—Staggering; keeps the 
hind-quarter resting against the wall, as though to prevent 
falling; staring, anxious eye. Patches of urticaria rapidly 
breaking out over the body. 12.44.—Pulse 64, weary. Spas¬ 
modic twitching of the pectoral muscles ; staggers much in the 
hind-quarters. 12.53.—Straining, but nothing passed; so 
restless now that the respiration cannot be counted; the wound 
is swollen and painful; urticaria profuse; drinks freely of cold 
water; eats hay. 12.59.—Looks sleepy; staggering; left off 
eating. 1.12.—Same state; right fore-leg twitching in a spas¬ 
modic manner. 1.20.—Intense restlessness; staggering; tre¬ 
mulous action throughout the whole muscular system. 1.27. 
—Drin k s water freely; tries to move about in the loose box, 
but staggers so much that it keeps on its legs with difficulty. 
The right side of the upper lip seems paralysed. Pawing 
restlessly with right fore-foot. 1.32.—Lies down. 1.36.— 
Peculiar spasmodic action of panniculus carnosus. The Horse 
is evidently dying; convulsive plunging of all four legs. Head 
drawn towards the chest. (This, Mr. E. says, is very unusual.) 
1.42.—Muscular twitching over the whole body. L43.— 
Dead. Bitten at 12.22. Died at 1.42— i.e., in one hour and 
twenty minutes. 
Post-mortem one hour and a half after death :—Lungs, 
slight hypostatic congestion; surface, natural colour. Heart.— 
Cardiac cavities distended with firm coagula. The clots 
were very firm, and were partially decolorized, probably 
indicating their ante-mortem origin. The great venous and 
arterial trunks, especially the aorta and vense cavee, plugged 
with firm coagula ; blood that was removed from the jugular 
vein found after death coagulated firmly. Blood examined 
under microscope, with No. 3 eye-piece, ^-incli object-glass, 
Nachet, was natural; no change in the corpuscles. The liver 
and spleen were normal, not in the least congested. There was 
rigor mortis. I examined the blood of the Horse killed by the 
Daboia about eighteen hours after death; it was dark and per¬ 
fectly fluid; no coagulum had formed. On placing a drop of 
it under the microscope, the field was filled with rhomboidal 
tabular and acicular crystals probably of hsemato-crystallin, in 
great abundance. The corpuscles appeared to have been dis¬ 
solved or disorganized, and the few that I could find after 
repeated examinations were apparently the ordinary blood cor¬ 
puscles shrivelled and partially broken down. The weather 
being hot and damp, the blood had probably become somewhat 
decomposed, and therefore I am unable, beyond describing the 
crystals, to give a very reliable account of the changes that had 
occurred. It appears to me it is in a case like this, where 
death was protracted, that if any structural changes take place 
in the corpuscles, one should find them. I was unable to 
detect any such changes; but as the examination was neces¬ 
sarily somewhat imperfect, I cannot say certainly, in this case, 
that they did not really occur. It was remarked just before 
and after death, that there was a peculiar pallor of the mucous 
membrane of the mouth. The relative disproportions between 
the pulse and respiration are accounted for by a disordered con¬ 
dition of the pulmonary air cells known in stable language as 
“ broken-winded,” which was present to a certain extent in 
both these animals. 
September 26 th, 186S. 
Experiment No. 3. 
Present, Dr. Fayrer, Professor Partridge, and Mr. Sceva. 
At 12 a Daboia, two-thirds grown, was bitten in three 
places in the thoracic region, from a foot to six inches 
from the head, by a full-grown, fresh, and vigorous 
Cobra. There could be no doubt that this snake was well 
bitten ; the Cobra imbedded his fangs viciously, and kept his 
hold for some time. There were blood marks after each bite. 
12.55.—No effect. 2.2 p.m. —No effect. 5.—The Daboia is 
apparently unaffected. 
September 27th, 10 a.m. —No change. 
28tli, 2 p.m. —No change. 
30th —No change. 
October 2nd.—Still alive and well. 
Experiment No. 4. 
A full-grown Cobra was bitten by another full-grown, fresh, 
and vigorous Cobra in the body in two places, about six inches 
from the head, and also in the mouth. They both bit each 
other freely in this situation—blood was drawn by the bites— 
at 12 o’clock. 12.55.—No effect. 2.2 p.m. —No effect. 5.— 
Both perfectly well. 
September 27th, 10 a.m. —No change. 
2Sth, 2 p.m. —No change. 
30tli, noon.—No change. 
October 2nd, noon.—No change. 
Experiment No. 5. 
A. large black Cobra was bitten about 12 o’clock in the body 
in two places, a foot and six inches from the head, and also 
on the head, by a large and vicious Daboia; blood was slightly 
drawn. There could be no doubt that the fangs had penetrated, 
or that the poison was inoculated. 12.55.—No effect. 2.2 
p.m. —No effect. 5.—No effect. 
September 27th, 10 a.m.— No change. 
28th, 2 p.m. —No change. 
30th, noon.—No change. 
October 2nd, noon.—No change. 
Experiment No. 6. 
A Domestic Fowl was bitten in the thigh by a Daboia at 12.15. 
It rvas convulsed immediately, and quite dead at 12.16.40. 
Dead in 100 seconds. The blood coagulated after death. 
Experiment No. 7. 
A hypodermic syringe filled with about thirty drops of the 
blood, taken from the above Fowl immediately after death, was 
injected into the thigh of another Fowl at 12.20. It walked 
about; was soon rather lame in the injected leg; gradually 
became sluggish ; drooped; could walk if roused, but remained 
quietly crouching. It gradually drooped and died at 4.10 p.m. 
Experiment No. 8. 
Mr. Sceva injected the blood of the Fowl (Experiment No. 7) 
into another Fowl’s thigh at 4 p.m. 
September 27tli, 10 a.m. —Fowl still alive. 
September 28th, 2 p.m.— The Fowl is alive and apparently 
well, excepting slight lameness in the injected leg. 
30tli, noon.—It is still alive. There has evidently been no 
effect produced. 
October 2nd.—The Fowl recovered. 
Experiment No. 9. 
A Domestic Fowl was bitten by a large Cobra in the thigh at 
12.19.5, and fell into convulsions immediately, and was dead in 
fifty seconds. Blood coagulated after death. 
Experiment No. 10. 
A hypodermic syringeful of the blood of the Fowl bitten by 
the Cobra in Experiment No. 9, taken from the heart, was in¬ 
jected into a Fowl’s thigh at 12.29. 12.32.—Sluggish; lame 
in punctured leg. 12.47.—Walks about, but is drowsy. 1.24 
p.m. —In much the same sluggish state ; another syringeful of 
the serum that had separated in the clotting of the same blood 
(that of No. 9) was again injected into the Fowl’s thigh. 1.52.—
