In full: "We will send the desired copy of Museum Miscellanea if one can be found, although the supply is nearly if not entirely exhausted. At present in the absence of Dr. Stimpson we cannot conveniently furnish specimens of radiates - crustaceans as desired, but hope to be able to do so hereafter. We should be pleased to receive from you the diatomaceous earth in considrable quantity for distribution to correspondents, as we are now about making up sets for the purpose from different localities. About a pint of each lot would be desirable or as near that amount as convenient. Very respectfully. Your obedient servant".
