Imperfect digestion is very often caused by defective teeth or by undue haste in eating, so that the food is bolted instead of being sufficiently masticated and insalivated.
I lost count after listing more than thirty different kinds, all plucked and then masticated with his cheek teeth as we walked along.
To convert the masticated rubber into rectangular blocks, it is first softened by heat, and then forced into iron boxes or moulds.
