To Alphonse de Candolle   25 May [1839]

Mr & Mrs C. Darwin (having heard from M^me. de Sismondi of M. de Candolle’s arrival in London) request the favor of M. de Candolle’s company to dinner on Monday next May the 27^{th 1} at six o’clock to meet M^r Henslow Professor of Botany at Cambridge.

Mr Darwin only learnt today that Mr Henslow would be here on Monday & he therefore hopes that M. de Candolle will excuse the liberty he takes in hoping to see him at so very short a notice. 12 Upper Gower Street

Saturday May the 25^th.
