BEES AND WASPS — GENERAL INTELLIGENCE. 183 
could not pursue a similar course with her. At first, then, I was 
afraid that she was doomed. I thought, however, that I would 
wash her, fully expecting, indeed, to terrify her so much that 
she would not return again. I therefore caught her, put her in 
a bottle half full of water, and shook her up well till the honey 
was washed off. I then transferred her to a dry bottle and put 
her in the sun. When she was dry I let her out, and she at 
once flew to her nest. To my surprise, in thirteen minutes she 
returned, as if nothing had happened, and continued her visits 
to the honey all the afternoon. 
This experiment interested me so much that I repeated it 
with another marked wasp, this time, however, keeping the 
wasp in the water till she was quite motionless and insensible. 
When taken out of the water she soon recovered ; I fed her ; 
she went quietly away to her nest as usual, and returned after 
the usual absence. The next morning this wasp was the first 
to visit the honey. 
I was not able to watch any of tb^e above-mentioned wasps 
for more than a few days ; but I kept a specimen of Polistes 
Gallica for no less than nine months. 
This is the wasp which has already been alluded to 
under the heading 6 Memory ; 5 but it is evident that the 
capacity which the insect displayed of becoming tamed 
implies no small degree of general intelligence ; its 
hereditary instincts were conspicuously modified by the 
individual experiences incidental to its domestication. 
The remaining passages that deserve quotation are the 
following - 
It is sometimes said of bees that those of one hive all know 
one another, and immediately recognise and attack any intruder 
from another hive. At first sight this certainly implies a great 
deal of intelligence. It is, however, possible that the bees of 
particular hives have a particular smell. Thus Langshaft, in 
his interesting 4 Treatise on the Honey-Bee/ says : ‘ Members of 
different colonies appear to recognise their hive companions by 
the sense of smell ; and I believe that if colonies are sprinkled 
with scented syrup, they may generally be safely mixed. More- 
over, a bee returning to its own hive with a load of treasure is 
a very different creature from a hungry marauder ; and it is 
said that a bee, if laden with honey, is allowed to enter any 
hive with impunity.’ Mi. Langshaft continues, f There is an 
air of roguery about a thieving bee which, to the expert, is as
