The toxicity of fourteen plants were investigated. The symptoms and post mortem appearances caused by three plants, which have previously not been proved poisonous, are described. These three plants are (a) Epaltes alata Steetz. (b) Homeria pura N.E. Br. and (c) Albuca sp. (O.P.H . No. 6726, 3.10.33; N.H.P. No. 15726). According to the results of the experiments conducted no definite opinion as to the toxicity of Zygophyllum foetidum Schrag. can be expressed. An acid environment has no effect on the active principle of gifblaar in the course of twenty-four hours.
