at costiveness, which they are liable to in hot
summers; and which has been thought to occasion canine madness, but which,
like their white excrement, is more probably owing to the deficient
secretion of bile. Whether these odoriferous particles attend the
perspirable matter in consequence of the increased action of the capillary
glands, and can properly be called excrementitous; that is, whether any
thing is eliminated, which could be hurtful if retained; or whether they
may only contain some of the essential oil of the animal; like the smell,
which adheres to one's hand on stroking the hides of some dogs; or like the
effluvia, which is left upon the ground, from the feet of men and other
creatures; and is perceptible by the nicer organs of the dogs, which hunt
them, may admit of doubt.

M. M. Wash the parts twice a day with soap and water; with lime water;
cover the feet with oiled silk socks, which must be washed night and
morning. Cover them with charcoal recently made red hot, and beaten into
fine powder and sifted, as soon as cold, and kept well corked in a bottle,
to be warned off and renewed twice a day. Internally rhubarb grains vi. or
viii. every night, so as to procure a stool or two extraordinary every day,
and thus by increasing one evacuation to decrease another. Cool dress,
diluting liquids?

15. _Crines novi._ New hairs. The black points on the faces of some people
consist of mucus, which is become viscid, and which adheres in the
excretory ducts of the glands of the skin; as described in Class I. 2. 2.
9. and which may be pressed out by the fingers, and resembles little worms.
Similar to this would seem the fabrication of silk, and of cobweb by the
silk worm and spider; which is a secreted matter pressed through holes,
which are the excretory ducts of glands. And it is probable, that the
production of hair on many parts of the body, and at different periods of
life, may be effected by a similar process; and more especially as every
hair may be considered as a slender flexible horn, and is an appendage of
the skin. See Sect. XXXIX. 3. 2. Now as there is a sensitive sympathy
between the glands, which secrete the semen, and the throat, as appears in
the mumps; see Hydrophobia, Class IV. 1. 2. 7. and Parotitis, Class IV. 1.
2. 19. The growth of the beard at puberty seems to be caused by the greater
action of the cutaneous glands about the chin and pubes in consequence of
their sympathy with those of the tes
