. British bee journal & bee-keepers adviser. Bees. 80 THE BRITISH BEE JOURNAL. [July 1, 1883. we cut open the honey-stomach and place the mouth of the stomach with its gullet carefully prepared under the microscope, we immediately see in the middle of the organ a very prettily constructed hody whose natural colour is an intense yellowish hrown. It is made prominent in figs. 1, o, C, 7, by darker shading; and it is this apparatus which Swammerdam describes as shading from yellow into red. It is the most important part of the organ. I am certainly justified in calling it the framework of the mouth of the stomach. For it consists of a very hard and touch skin, extremely chitinous, which upwards affords the firm basis for four lips, and below determines the width of the gullet of the mouth of the stomach. The lips, which taper to a rather acute point, form a regular four- sided pyramid, so that each right margin of a lip joins the left margin of its neighbour and so closes the mouth securely. I have, in fig. 2, drawn a four-sided pyramid in order to show our readers distinctly all the four lips in their mutual junction. For the sake of clearness the isosceles triangles are only indicated by their boundary lines. I need scarcely say that in nature the lips do not have the stiff form and shape of a mathematical triangle, which may be very well seen from the other figures. As far as the gullet combines with the wall of the mouth of the stomach, the chitinous formation vanishes,.
