Jean Ferdinand Caius

He completed theological studies at Kurseong and then at St Beunos College in North Wales.

His work on medicinal plants and animal toxins led to his being appointed as a pharmacologist to the Haffkine Institute in Bombay in 1924.

They found that salivary gland extracts of some snakes considered non-venomous had toxic effects.

[7][8] He was also involved in a BNHS study of the attraction of mammals to salt licks and the composition of the soils.

This included a major series on the poisonous plants of India which he wrote right until the time of his death.
