I sent by Hospital Steward Marshall one model of boat used by Indians in Alaska Territory, one waterproof bag from Alaska made of seal membrane, two beavers teeth, two walrus teeth. These articles I contribute as curiosities that may be acceptable to the Curator for presentation and as objects of illustration and information. They have been acknowledged as contributed by Mr Marshall himself. Will you please make the change rendered necessary by my omission and send a formal communication.
Very Respectfully & truly yours
