At the posterior end this merges with the proventriculus, with heavy muscular walls, which contains a valvular ap- paratus (Fig. 61). Behind this is the stomach or ventriculus (Vent). Schonfeld claims that the brood food, especially that of the queen (royal jelly), is regurgitated from the ventriculus. The experiments of Schonfeld seem to show that the valve in the proventriculus opens and moves anteriorly even to the oesophagus when this is done, but Snodgrass' claims that this cannot be done without tearing the mus- cles of the proventriculus. Cowan and other authors figure this action in a diagram, but with no evidence from observation. Schonfeld and Cook fed charcoal in honey and found this in the brood food which would, in their esti- mation, be impossible if the food is of glandular origin, but they overlooked the fact that the charcoal might get into the brood food from the mouth of the worker. The char- coal could not pass through the walls of the ventriculus in. Fig. 61. — Longitudinal me- dian section of base of oesophagus. 1 Cook, A. J., 1904.
