Letter from Srinivasa Ramanujan to Eric Harold Neville

Matlock Sanatorium, Matlock, Derbyshire. - Thanks Neville and his wife; had a letter of congratulation from Neville's brother [on Ramanujan's election as a fellow of Trinity]; is very sorry [Neville's brother] is having sleepless nights.

Became very ill after Neville saw him last and has not recovered; was much worse in March and April. Is currently investigating a continued fraction, which he writes out; discusses some of its properties with mathematical notation.

Hopes that Neville and his wife are well, and sends them kind regards.
