years was completed before he left for home. In the meanwhile the American Board decided to discontinue the medical work of its missions (which was later reversed). But for this decision, Dr. Green would have returned again to Ceylon.

Twice during his lengthy stay in Ceylon, the Cholera epidemic broke out and the devastation, would have been incalculable had it not been for Dr. Green's help. In 1855, he himself suffered an attack and on his recovery helped in the cure and prevention of this dreadful disease. Eleven years later, the epidemic struck again and thousands fell a prey to it.
