ANIMAL INTELLIGENCE. 
Buchner’s very admirable collection of facts relating to the 
psychology of Hymenoptera 
Herr L. Brofft relates, in c der Zoologische Garten ’ (XYIIT. 
Year, No. 1, p. 67), that a poor and a rich hive stood next each 
other on his father’s bee stand, and the latter suddenly lost its 
queen. Before the owner had come to a decision thereupon the 
bees of the two hiv r es came to a mutual understanding as to the 
condition of their two states. The dwellers in the queenless 
hive, with their stores of provisions, went over into the less 
populous or poorer hive, after they had assured themselves, by 
many influential deputations, as to the state of the interior of 
the poor hive, and, as appeared, especially as to the presence of 
an egg-laying queen ! 
General Habits . 
■ 
The active life of bees is divided between collecting 
food and rearing young. We shall therefore consider 
these two functions separately. 
The food collected consists of two kinds, honey (which, 
although stored in the 4 crop 5 for the purpose of carriage 
from the flowers to the cells, appears to be but the con- 
densed nectar of flowers) and so-called 4 bee-bread.’ This 
consists of the pollen of flowers, which is worked into a kind 
of paste by the bees and stored in th eii cells till it is re- 
quired to serve as food for their larvae. It is then partly 
digested by the nurses with honey, so that a sort of chyle 
is formed. It is observable that in each flight the 4 carrier 
bees 5 collect only one kind of pollen, so that it is possible 
for the 4 house bees ’ (which, by the way, are the younger 
bees left at home to discharge domestic duties with only 
a small proportion of older ones, left probably to direct 
the more inexperienced young) to sort it for storage in 
different cells. In the result there are several different 
kinds of bee-bread, some being more stimulating or nu- 
tritious th n others. The most nutritious has the effect, 
when given to any female larva, of developing that larva 
into a queen or fertile female. This fact is well known 
to the bees, who only feed a small number of larvae in this 
manner, and the larvae which they select so to feed they 
place in larger or 4 royal 9 cells, with an obvious fore
