Chinese hedgehog

— In the first place let us describe the “Chinese hedge-hog”. This is a wreath of fine soft feathers, with their quills solidly fastened by silver wire to a ring of the same metal, made in various sizes, and sufficiently large to slip over the gland, when the penis is not in erection, and small enough to be stopped by the ring of the gland when the penis is erect. This machine sensibly increases the size of the penis, aud [sic] it will be easily understood that the friction of the feathers against the mucous surface of the vagina produces sensations of a peculiar effect.
