Sir,

I am happy to inform you that the French translation of your book on the fertilisation of Orchids is published, and I have requested Mr Reinwald, the publisher, to send you immediately a copy, which I gratefully beg you to accept.¹

I have not had the honour to write to you since a long time about this publication, which required a little time more than had been formerly supposed;² it is now completed, and I feel highly gratified to have been the means of presenting your valuable work to the French public; I feel convinced that, if my translation is not too inferior, I have done a useful thing in making my countrymen acquainted with another of your works;³ your approbation alone is wanting to complete my satisfaction.

Should you desire to present a few copies to any friends of yours, I shall feel most happy to send you some.

I have the honour to be, Sir, your most obliged and respectful servant | Louis Rérolle
