EXPERIMENTS ON THE TRANSMISSION OF SCARLET FEVER TO THE LOWER MONKEYS

1. The reported successful transfer of scarlet fever to both higher and lower monkeys is not definitely established. 2. In the course of the experiments here reported, the infectious agent can be assumed to have been carried over to the monkeys. The failure to cause infection probably proceeds from the insusceptibility of the monkeys employed, or to the manner of introducing the agent. 3. The temperature curve and leucocyte count of monkeys are unsatisfactory criteria for the diagnosis of disease in those animals. 4. Monkeys frequently have transient blotchy, erythematous eruptions on the face and neck, and almost always a bran-like desquamation. 5. Monkeys are highly resistant to infection with microorganisms from human beings.
