incrassation

At least that which has usually been termed, with more or less awe, the supernatural, the ghostly, has impinged upon the mental incrassation of sensual man as a thing to be reckoned with in daily life; no longer to be relegated to the region of vague darkness d'outre tombe.

It is capable of exerting sufficient friction under the brush to ensure pearly whiteness of the teeth without injuring the enamel, whilst the camphor in it tends to destroy the animalcula in the secretions of the mouth, whose skeletons or remains constitute, as we shall presently see, the incrassation popularly called “tartar.”

Subsequently the antennae become thickened, two, three, or four of the first joints of the flagellum are fused together, the palm of the hand acquires a deep emargination near its inferior angle, and the intermediate joints of the last pair of feet become swelled into a considerable incrassation.
