Morgan arrived in New York about June 3 and purchased some additional drugs there. By June 17 his staff had made up 30 medicine chests for the regiments at New York as well as for "the branches of the General Hospital at New-York, in the bowry and neighborhood and at Long-Island." But the number of regiments requiring medical supplies exceeded Morgan's expectations, particularly since he had been advised that "the Southward regiments" would be supplied by Congress in Philadelphia.[50] By the middle of June, Morgan must have realized that the supply of drugs available was inadequate despite the sizable quantity brought from Boston and the small stock he was able to obtain in New York. It appears that many of the New York druggists were Loyalists, and somehow they and their stock of drugs disappeared when needed by Washington's army. For example, druggist Thomas Attwood "removed his store consisting of a general assortment of Drugs and Medicines" to Newark in May only to reappear in New York again under British occupation with a good stock of "Drugs and Medicines."[51] The New York Committee of Safety had attempted to develop a stock of drugs early in the year when they were plentiful,[52] but in June this supply was valued at only L30. Even this small stock was not available to Morgan because when he asked permission to purchase the medicines at "a reasonable price ... for use of the Continental Hospital" the New York Provincial Congress rejected his plea on June 26 with the explanation that this medicine was to be "reserved for the use of the poor and other inhabitants of this city."[53] With increasing demands to supply the troops in the Northern Department, Morgan turned to Philadelphia and the Continental Congress. Morgan owned a small stock of drugs in Philadelphia, and knew of another supply in the possession of the firm of Delaney and Smith,[54] so he sent Dr. Barnabus Binney to Philadelphia to forward "with all dispatch" what medicines he had there and whatever could be obtained from Congress.[55] Congress resolved on July 17 "to purchase the Medicines (now in Phila) belonging to Doctor Morgan,"[56] but for nearly a month Binney was unable to obtain any additional supplies either from Congress or from private sources. On June 25 Morgan wrote to Samuel Adams asking for power "to demand a proportion of the Continental medicines left in care of Messrs. Delaney & Smith," and he repeated the request in July. However, Morgan's only reply from Adams, dated August 5, made no mention of the Delaney and Smith drug stock. Instead Adams wrote only: "I have received several letters from you, which I should have sooner acknowledged, if I could only have found leisure. I took however, the necessary steps to have what you requested effected in Congress."[57]
