The further pathological effects of Pseudechis venom arise in Ws 
three ways— oo 
(1) Those due to the direct action of the venom on the cells of 
the affected part. 
(2) Those secondary to hemorrhage. 
(3) Those secondary to thrombosis. 
As regards its power to induce anatomical changes in the victim, 
Pseudechis venom appears to occupy a position about midway — 
between cobra poison and the poison of the viperine snakes. 
Its action in separating the hemoglobin from the corpuscles — 
has already been described. The free hemoglobin finds its way — 
out of the body, through the kidneys and liver, and so is found — 
staining the urine and bile, in the former of which it is often 
present in crystalline form. It also passes into the fluid contained 
in the pericardium, and other serous sacs, and even into the 
aqueous humour. The staining of all these fluids is independent — 
of any hemorrhagic action of the venom, and has been of almost 
constant occurrence in my experiments with different kinds of : 
animals, whenever they have lived more than one to two hours. 
I have already shown that this venom affects the endothelial e- 
wall of the blood vessels, so as to permit of the escape of their me : 
tents, and although it does not appear to be nearly so active 
causing hemorrhages as that of Crotalus, or other viperine snakes, 
extravasations of blood into important organs and hemorrhages 
from the mucous surfaces, do however sometimes play an importan’ 
part in the symptoms of poisoning. The distribution and ex 
of the heemorrhages vary under the different experimental io 
ditions in exactly the same way as Feoktistow (whose description 
I quote above), has observed the hemorrhages following Crotalus 
poisoning to vary. As was found to be the case with the latter 
poison, dogs are particularly sensitive to this action of the veno 
Hemorrhages are most marked in those animals which live about 
two days. The operation of the venom in other directions _ : 
most favourable to the occurrence of hemorrhages, in addition
