appeared; but the pain in the hand had increased greatly and 
was almost unbearable. Boring a hole with a red-hot iron comes 
nearest to the effect. 
At 2.30 the pain in the hand was still violent, extending 
through to the palm, the ball of the thumb and base of the 
first finger. The weakness was so great that I could not grasp 
anything with any force. 
At 5 o’clock the burning pain was much diminished, but 
there was a dull aching pain all over the hand. 
At 6 o’clock the burning had quite given place to the dull 
pain, but the place of contact was still very much inflamed and 
sore to the touch. There was a dull red patch about an inch 
in diameter round the spot, and the soreness reached some 
distance beyond this, even as much as three inches in the dir- 
ection of the arm. The weakness in the hand was still considerable. 
At 8.30 the pain was still there though much reduced. The 
red patch and soreness much the same. The immediate neigh- 
bourhood of the affected part still perspiring. The wet bandage 
did not seem to do any good, so I removed it after it had been 
on about an hour. I afterwards tried olive oil on the place but 
it had no effect. At 10 o’clock I went to bed, the aching in 
the hand still being pretty bad. At 1.30 a.m. I awoke with the 
pain still considerable, and the soreness very great. Next day the 
pain had quite gone, but the soreness continued till the day 
after. The marks of the points of the spines, 36 in number, 
are still visible (March 16th).” 
After the above experiment I think we may safely say that 
any bird or mammalian that tackled one of these caterpillars 
would not be inclined to repeat the experiment, and I myself 
am certainly not prepared to do so.
