1876.]  Lubbock’s Observations on Bees and Ants. 155 
I quote the following in order to show the steadiness with 
which ants work. 
July 13th. At 6.20 a. m. I put an ant to some honey; at 6.40 
she went, at 7.02 she returned, and at 7.08 went away again, but 
not to the nest ; at 7.11 she returned, and at 7.15 went away again. 
At 7.27 she came back. 7.40 went. At 1.30 she came back; at 1.41 went.

after which she came back no more. During this time fifteen 
others had come to the honey. 
That ants have a certain power of communication has been 
proved by Huber and other observers. Several striking cases are 
mentioned by M. Forel. For instance (op. cit., page 297), an 
army of Amazon ants, on an expedition in search of slaves, at- 
tacked a nest of Formica rufibarbis. In a few seconds (quelques 
secondes) the dome of the nest was covered with F. rufibarbis, 
which rushed out to defend their house. 
On another occasion he placed a number of Tetramorium cces- 
Pitum about four inches from a colony of Pheidole pallidula. 
“En un clin d’wil,” he says (page 384), “ l’alarme fut répandue, 
et des centaines de Pheidole se jetérent au devant de lennemi.” 
Again, he (page 349) placed some earth containing a number 
of Tetramorium about four inches from a nest of Strongylogna- 
thus Hubert, Several combats took place; but after the lapse of 
à few minutes (quelques minutes) a whole army of S. Hubert 
merged and attacked the intruders. 
another occasion, some Amazon ants (page 301) were 
Searching in vain for a nest of Formica rufibarbis. After a while 
ome of them found thenest. * Immediately ” (aussitôt), he says, 
à signal was given, the Amazons rushed in the right direction, 
and pillaged the nest in spite of its inhabitants.” This is a sur- 
Prising statement. If itis to be taken literally, the communi- 
“ation cannot have been made by the antenna ; the signal can
