Sir
I have persuaded the Council of this institution to part with the Specimen of the Gymnotus Electrivus which has now been a year in our possession for although by care, we have brought the animal to a state of most vigorous health from one of extreme debility in which it was when it came into our possession, yet I am conscious that to preserve its health more light and purer air, are necessary than we have the means of affording it here. I have been, accordingly, directed to apply in the first instance, to you as Secretary of the Zoological Society, to offer it to that Society, which it might be presumed would be most interested in possessing it. I shall be happy to impart the results of my experience in the treatment & management of the Fish which certainly has hitherto proved successful. I may in conclusion state that the price at which we should part with the Fish is 50£ & I must request as early an answer as convenient as I should offer it to other Institutions in case of the Zoological Society declining the purchase.
I am Sir
Yours faithfully
Thomas Bradley
