Thanks for Smith's "Tracts of Natural History", especially pleased with the account of [Conrad] Gesner [(1516-1565) Swiss naturalist]; discusses Gerard's death. Taking foxglove ['Digitalis'] for his anascara. Was introduced to Mrs Kindersley [a relation of Smith's] the last time he was at Bath, [Somersert]. Asks if Smith knows anyone who can give an account of the colours used in "Hindostan paintings", specifically if any are chemical.
