1. 1. Rickettsialpox is a new rickettsial disease transmitted to man by the rodent mite. 2. 2. The disease thus far is confined to New York City but may conceivably occur elsewhere in endemic form. 3. 3. Rickettsialpox is a benign disease characterized by chills, fever, sweating, backache, headache, general malaise, and a maculopapular vesicular exanthema and an oral enanthema. 4. 4. Diagnosis is established by the clinical course and the complement fixation test. 5. 5. Aureomycin and Chloromycetin may prove to be therapeutically effective.

Repetitive behaviors of six autistic children were observed under two conditions of background illumination. During two sessions, the room was illuminated by fluorescent light and during two other sessions, by equal intensity incandescent light. Subjects spent significantly more time engaged in repetitive behavior under fluorescent light. Previous research suggested that these findings were related to the flickering nature of fluorescent ilumination. Practical and theoretical implications were discussed. Further experimentation was suggested to assess relationships between flickering illumination and arousal.

A case is reported in which multiple papillary excrescences occurred on the buccal mucous membranes. The white, flattened tumors were so numerous as to appear confluent, but on close examination were each seen to have a broad pedunculated base. The tumors were characterized histologically by acanthosis, parakeratosis, and vacuolization of epithelial cells. There was no ulceration of these lesions, or other evidence of neoplastic degeneration.
