ON THE REPUTED 
never been injured by it, and I have kept such scorpions for 
days afterwards in a perfectly lively and healtby condition. 
Series B. — I have carried out an equally large number 
of experiments, using one scorpion to sting anotber, and, as 
before, in no case was there any inj urious effect. 
Series 0. — These were commenced to test the efficacy of 
my method of stinging. I stimg a small frog in the thigh. 
There was a marked general effect, the frog was very quiet 
for some time and seemed to avoid using the limb stung, 
but quite recovered in a few hours. A chicken was stung in 
the thigh which evidently caused it great inconvenience, it 
hopped about on one leg for half-an-hour and then crouched 
down apparently very uneasy, but it got up fi'om time to 
time, and in about an hour or so was ready to feed. The next 
morning it seemed perfectly well, but cried out violently 
when brought near a scorpion. I tried a simple puncture 
experiment on another chicken to show that the effect was 
not due to a mere puncture, which seemed to have very little 
effect. I have constantly given these two chickens dead 
scorpions to eat, which they do greedily. On one occasion 
I gave them a living scorpion, which they attacked, but one 
of them got stung near the root of the beak ; it was ill for 
some hours ; its symptoms were similar to those mentioned 
above. It is evident that under ordinary circumstances a 
scorpion's sting is not fatal to a chicken. 
I next tried various insects. A cockroach stung between 
the thoracic terga becomes almost instantly pai'alysed, a mere 
puncture made in the same place has little or no effect. The 
cockroach does not generally die until some time afterwards. 
I have seen a cockroach lie on his back after being stung, 
just twitching his legs and maxillte, and remain alive for 
24 hours. 
I procured some lai'ge locusts and stung them in the 
thigh of one of the third pau- of legs, that leg instantly 
becomes paralysed and the animal moves about on the
