His services were gratuitous, he made no show to attract customers, and being ready to aid the native physicians with both medicine and instruction he gave them no offense.
Dr.Grant possessed a rare fitness for the position.

I have a vivid recollection of him at the time of the annual meeting of the Board at Utica in 1834, when he presented himself, one stormy evening, to offer his services as a physician for the mission to the Nestorians.
What specially impressed me was his commanding form and mien, joined with calm decision and courage, qualities eminently fitting him for a life in Koordistan.

The impressions made by that brief personal interview, were sustained and strengthened through a most intimate correspondence till his death.
It is in the early stage of a mission, that the value of a pious physician is most apparent.

With the exaggerated conceptions usually entertained of the temporal blessings he is able to confer, he is welcomed by all classes from the first.

Every door is opened, every man and woman is accessible.
