| English abstract | The ground seeds of Ricinus communis, given by stomach tube in single doses to rabbits, caused severe symptoms of poisoning, lethal in three rabbits which received the dose of 2 g/kg and in one of four rabbits which received 1 g/kg; the other three rabbits which received the lower dose, showed slight to moderate symptoms and recovered. Three other rabbits, which received 0.5 g/kg, showed only slight symptoms. The period between administration of the seeds and death or recovery, varied from 12h47min to 68h08min, and from 3 to 6 days, respectively.

The course of the poisoning varied from 4 to 56 hours in the lethal cases and from 2 to 5 and half days in the cases with recovery.
