Ecthyma may sometimes have a rupia-like appearance. On the other hand, I would emphasise the fact that the secondary ecthymatous syphilides are seen in the ill-fed and neglected, but here the concomitant signs of syphilis would serve to differentiate it from simple ecthyma. Inveterate Pediculosis vestimenti (lousiness of the body) may occasion a good deal of pustulation about the upper part of the body (shoulders, and so forth). The distribution of the rash and the presence of the Pedicnlus in the vest or garment worn next the skin would decide the matter. The parasite has six legs and is therefore an insect. The minute blood- speck resulting from the insertion of the parasite’s proboscis into the skin, just visible to a good eye and better seen with a lens, is a point of diagnostic value when it is present. In Scabies (itch, la gale, die Kriitze), the multi- formity of the lesions has also led to suspicion of syphilis, in fact to the positive diagnosis of the latter disease, especially as in men the penis is frequently affected. The great points are the distribution of the rash, in males from about the transverse nipple line to the knees in front, including the genital area, and about the buttocks behind. Scratch marks and pustules on the buttocks and penis are always to be regarded from the point of view of scabies. In women, the arrangement of the clothing somewhat
