Summary

  1. 1.

    Solutions of normal human blood in plant-physiological media produce a definite inhibition of root growth ofLupinus albus seedlings, which yield an average index of 75 per cent.

  2. 2.

    Normal blood sera from a large variety of different animals give phytotoxic indices practically identical with that of normal blood. The principal exception was the blood of reptiles. Blood sera from non-venomous, as well as those from venomous snakes, were all toxic for plant protoplasm.

  3. 3.

    A marked toxicity forLupinus seedlings is exhibited by sera from certain diseases; i.e., from pernicious anemia, pemphigus and leprosy.

  4. 4.

    Blood specimens from a series of virus diseases yieldedatoxic readings; that is, were less toxic for plant growth than normal blood sera.

  5. 5.

    Blood sera from monkeys infected with poliomyelitis give readings within the normal range, while those obtained from trachoma patients exerted a marked toxicity.
