THE GENERAL SUBJECT. 
Ins. 3 
Orthoptera, Diptera^ Hyrnenoptera^ and Lepidoptera^ including carnivorous 
and herbivorous species, the author modifies his former opinion (Mem. 
Ac. Belg. xli. ; Zool. Rec. xi. p. 242) that in a normal condition the 
digestive juices of all insects are alkaline or neutral, and never acid. 
He now admits a slight acidity in the carnivorous and polyphagous 
species, but adheres to the alkaline nature of the fluids in perhaps all of 
the vegetable feeders. In these latter, the natural acidity in their 
pabulum is either neutralized in the alimentary canal or yields to an 
alkaline reaction during digestion ; though a certain degree of acidity 
reappears in the excreta, probably owing to partial decomposition.
