Sun. Eve [1840]

Sir
I have the pleasure to send you my description of the Silurus and of its anatomy. You will perceive that my memory was not quite correct, for instead of a long Dorsal my [Diclioo Mutchie] has a long Anal fin. The former according to other of my memory is the Heterobranchus of Geoffroy St Hilaire and is likewise endowed with the same singular conformation of the Bronchia which he has described while Cuvier repeats in his Anatomie Comparee.
I will see you in the afternoon of tomorrow and explain further -

I am
Sir
Your very Obed. etc
