Mr. Hunter's Observations on Bees. 181 
come out from a bag. It passes almost directly downwards 
in the middle of the abdomen. Its inner surface is very 
much increased, by having either circular valves, somewhat 
like the valvulce conniventes in the human jejunum , or spiral 
folds, as in the intestine of the shark, &c. ; these may be 
seen through the external coats. In this part the food under-

When bees are hungry, as a young swarm in wet weather, 
and are in a glass hive, so that they can be examined, if we 
put some honey into the bottom, it will immediately breed 
a commotion; they all seem to be upon the scent: even if
