298 PHILOSOPHY OF ZOOLOGY. 
appears to be very generally used. The antennz perform 
the office; and in the manner in which they are applied to 
the antennz of another insect, and the motions which are 
executed by them, these organs are capable of communica- 
ting the state of feeling with great precision. When a queen 
bee, for instance, is removed from a hive, those bees which 
first perceive the loss, when they meet with others, nu- 
tually cross their antenne and strike them lightly. The 
anxiety and disturbed state of those that have received the 
blow, indicate plainly the nature of the intelligence which 
has been communicated. It is probable, that molluscous 
animals, furnished with tentacula, employ, in like manner, 
these organs in the communication of their feelings. 
We might here take notice of the mutual communication: 
of feeling, by means of smell, were the facts which are 
known, in connection with the subject, sufficient to illustrate 
this department of the animal economy. It is, however, 
well known, that, at the particular season when the procre- 
ative appetite is in exercise, smells are emitted which en- 
able the sexes to discover each other. ‘The emission of 
these effluvia cease with the season of love. 
However various these different means employed by ani- 
mals to communicate their feelings appear to be, it is ge- 
nerally believed, that man alone possesses the power of ex- 
pressing distinctly past events to others. The lower ani- 
mals are almost exclusively occupied with their present 
impressions ; and their language appears suited only to 
express these. I have said almost, because there is evi- 
dence of the power possessed by various animals, of com- 
municating intelligence to others of a supply of food which 
has been discovered, and of guiding them to the spot. But 
still this is im a great measure the business of the present 
time. Man, on the other hand, by means of his acquired 
language, can express the feelings which, on any former 
period, he has experienced; and, by means of artificial
