The internal structure of the cranium may be studied best in a longi- tudinal section of the head (fig. 11). In order to prepare a section for this purpose imbed the head in paraffin and then carefully slice off one side with a sharp knife or razor just outside of the bases of the mandible and antenna.

In order to prepare a section for this purpose imbed the head in paraffin and then carefully slice off one side with a sharp knife or razor just outside of the bases of the mandible and antenna. Holding the remainder in the block of paraffin or fastening the whole in a dish of water or alcohol, care- fully dissect away the soft parts from the head cavity so as to expose. Fig. 11.—A, longitudinal section through head of worker between the median plane and outer edges of mandibles (Mcl) and antennae (Ant) of left side, all internal soft parts removed; B, corresponding section through head of drone, except that the pharynx (Phy) and oesophagus (G?) are not removed. the internal chitinous parts shown in figure 11 A and B. These figures, however, represent a slice of the head taken from between the median plane and the outer edges of the antennal and mandibular bases of the left side. Thus only the parts on one side of the mid- line are shown. Figure A is from a worker and Figure B from a drone. In the latter the pharynx and oesophagus are retained and the neck is not removed. Figure 20 shows the head cut open from above and the mouth parts removed. A specimen so cut and boiled a shorl time in caustic soda or potash to remove the soft parts will be found a valuable adjunct to this Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Snodgrass, R.
