The operation was performed with the greatest care. I not 
only divided every nervous filament, however small, which I 
could detect, but every portion of cellular membrane in the 
axilla, so that the artery and vein were left entirely insulated. 
I then made two wounds in the fore-arm, and inserted into them 
some cf the woorara formed into a paste. Fourteen minutes 
after the poison was applied, the hind legs became paralytic, 
and in ten minutes more he died, with symptoms precisely 
similar to those, which took place in the former experiments, 
and the heart continued to act after apparent death. On dissec- 
tion, the nerves of the upper extremity were particularly exa- 
mined, but not the smallest filament could be found undivided. 
I made the following experiment to ascertain whether the 
woorara passes into the circulation through the absorbent 
vessels. 
Exp. 2 6 . 1 tied a ligature round the thoracic duct of a 
dog, just before it perforates the angle of the left subclavian 
and jugular veins. I then made two wounds in the left hind 
leg, and introduced some of the woorara in powder into them. 
In less than a quarter of an hour he became affected with the 
usual symptoms, and died in a few minutes afterwards. 
After death, I dissected the thoracic duct with great care. 
I found it to have been perfectly secured by the ligature. It 
was very much distended with chyle, and about two inches 
below its termination its coats had given way, and chyle was 
extravasated into the cellular membrane. The lymphatic ves- 
sels in the left axilla were distended in a very remarkable 
degree, and on dividing them, not less than a dram of lymph 
issued from the divided ends.
