The purpose of this study was to find out how the solubility of arsenate of lead is increased by the action of the digestive fluids present in the alimentary tract of an insect. In making these determinations, the honey bee, Apis mellifica Linn., was taken as the insect and the solubility of arsenate of lead powder in water was taken as the unit of solubility. The conclusions drawn from this experiment are as follows, (1) The solubility of arsenate of lead does not seem to increase when the powder is acted upon by the fluids in the oesophagus. (2) The digestive secretions of the honey stomach and stomach render the poison at least one and one quarter times as soluble. (3) The action of the intestinal juices is to throw at least three and three quarters times as much of the powder in solution as would be dissolved by water alone.
