This same author tells us how by pressing with a needle, while viewing the stomach-mouth under a microscope, we can see the jaws open and shut. These plates have fine hairs, pointing down (Fig. 62, h), which would, if a portion of the honey-containing pollen were taken by this very muscular stomach-mouth, retain the pollen-grains, while the honey could be passed back into the honey-stomach. Hence, Schiemenz very naturally concludes that this is a sort of strainer, constantly separating the pollen and honey as the bee is sipping nectar from flower to flower, Fig. i,\.. €)| ~d" ft ell iStomach-mouth in Money-ISto^nach^ after Cowan.

As will be seen, this stomach-mouth has not only great longi- tudinal muscles (Fig. 62, m), but also circular muscles as well (Fig. 62, ni). If Schiemenz is correct, then this stomach-mouth is to separate the honey and pollen. Even with this interest- ing apparatus, much of our honey has not a few pollen-grains, as every observing bee-keeper knows. The fact that nectar has much more pollen in it than does honey, makes Schie- menz's view all the more probable. There is also a long prolongation (Fig. 62, v) from the stomach-mouth into the true stomach. This is .04 of an inch long, and is rich in cells, which are held by a very delicate.
