The brain, like our own, is inclosed in membranes, is composed of white and gray matter, and is undoubtedly the seat of intelligence. Hence, as we should suppose, the brain of the worker is much larger than that either of the drone or queen. The ganglia along the cord are the seat of reflex acts the same as is the gray matter of our own sjainal cord. Indeed, the beheaded bee uses its members much more naturally than do the higher animals after they have lost their heads. This may arise from their more simple organism, or from a higher development of the ganglia in question. The organs of circulation in insects are quite insignifi- cant. The heart (Fig. 19, //) is a long tube situated along the back, to which it is held by large muscles (Fig. ly, w),.
