In the United States the laws relating to anatomy varied very considerably in the different States; there was no regular supply for the schools, and, consequently, subjects had to be obtained by the aid of resurrection-men. In Philadelphia and Baltimore, the two great Medical Schools of the United States in those days, the supply of bodies was obtained almost entirely from the "Potter's Field," the burial-place of the poorest classes. This exhumation was carried on by an understanding with the authorities that the men employed by the schools in this work should not be interfered with. Dissection in the United States was, as in this country, looked upon with great aversion; this was, no doubt, mainly owing to the fact that the bodies used for this purpose were obtained from the graves. CHAPTER IV. The Diary of a Resurrectionist is written on 16 leaves, but is, unfortunately, imperfect. The first entry is November 28th, 1811, and the last December 5th, 1812. There are no entries in May, June, and July; during these months there would be little demand for subjects, as the sessions of the Anatomical Schools ran from October to May. Besides this, the light nights would interfere with the work of the men. The entry under the date February 25th refers to this: "the moon at the full, could not go." The state of the moon was of great importance to these men in their work; the writer of the Diary has on one of the pages copied out the "Rules for finding the moon on any given day," and has set out the epact for 1812 and 1813.
