not even by the loss of them; others again get very sick, and 
then after awhile recover. 
3. On the same day I caught a long fly-like insect on my win- 
dow. Its antennz seemed very tender, even to the slightest touch 
of a straw. When one was cut off it did not seem to hurt it 
‘much. But when I put some pepper-sauce on the other it 
contracted it very much and ran around as if it were crazy. 
Once or twice it tried to clean it off with the mouth, but seem- 
ing to get a taste of the sauce, it did not use its mouth so again, 
but took its feet to it, and at the same time tried every few 
steps to clean both mouth and antenne by rubbing them on 
the window sill. The stump was not so much affected by the 
sauce, though it noticed it also. I might remark here that many 
grasshoppers act in much the same way under similar treatment. 
4. I caught five common crickets with the intention, at first, of 
trying to find out whether the power of direction resides in the 
antenna. Of one I cut off the right antenna, of one the left and 
of two both, leaving the other two whole. I then turned all five 
out on the floor. The deantennized ones did not notice it at first, 
but after a while they drew the remaining stumps several times 
through the mouth and then let them alone. I could find no dif- 
ference of movement among them, but all seemed as lively as 
crickets generally are. Failing to find anything like a sense of 
direction, I caught them again to try if I could find in the anten- 
ne anything like a sense of hearing. Among the other noises I 
made, I got a large jews-harp and played on it with all my might. 
But they took no notice of it, at least as far as the antennz were 
concerned, but sat in contemptuous silence, though I executed 
for them, to the best of my ability, many martial airs of the land 
with now and then a love song or a waltz. And let me say just 
here that another cricket whose antennæ I had cut away, and 
which I placed in the kitchen, “sang” all summer long. And 
also that of all the experiments I have made, I have not been 
able to find anything like a sense of hearing. Antennz all seem 
to be deaf, Next, with these same crickets, I experimented to 
find a sense of taste in the antennæ. Instead of using things 
which might taste well to them, I used some table mustard and 
Me pepper-sauce, Putting some of the mustard on the end of 
* straw I found that when I touched it on the antenne they 
Would remove them immediately. The stumps were not quite so
