Beetles : their Structure and Habits. From the popular point of view beetles have been thought to make a nearapproach to crabs and lobsters, for their entire outer integument is strengthened bythe deposit of much chitin, which renders it hard and horny, just as the similardeposit of chitin mixed with carbonate of lime makes the so-called shell of thecrab stony. This, of course, is merely an external resemblance : the internalstructure and organization of a crab are altogether different from those of a beetle. ^ .Sarco] liv J. Cuinras.
