(2) The vesicles, usually very small in scabies, may be larger on the wrist, where the skin is fine and expansible. They are clear and slightly acuminated. (4) Vesicles after suppuration increase in size and remain mixed with clear and non-infected vesicles. This mixture is very characteristic. (5) The streptococcic phlyctenules of impetigo are larger, less numerous, and often emptied of their turbid contents. The treatment of scabies is the same here as elsewhere.

Sometimes this consists of a round raised placard of suppurating trichophvtic follicles, of equine origin. This form is most common on the hack of the hand (p. 346).

At other times the trichophyton has variable forms and is of varied origin, the family of trichophytons presenting a great variety of species. Trichophytosis is recognised by the circinate form of the lesions, which are vesicular or vesiculo-pustular at the margin, polycir...
