This one-hundred-page volume contains Dr. Williams' daybook and accompanying account book, as well as lists of birth, death, and sale dates of "Negroes" - presumably his slaves.
This daybook gives a good indication of the extent of Dr. Williams' practice and plantation. Its entries include a debtor's or creditor's name, the guardian's name (where applicable), the amount owed, and a description of the service rendered or material sold. Medical services include doctor's visits, cutting gums, tooth extracting, cupping, purging, "midwifing," and even making a coffin. For these services, the patient's race was noted if "Negro." Other services were mostly those performed by Williams' slaves for members of the community and they include working at "the apple mill" or making various repairs. However, Dr. Williams apparently did do some surveying. Materials bought from Dr. Williams include various medicines as well as foodstuffs, tobacco, wool, and other miscellany.
Accompanying the daybook is an indexed, name-by-name record of most of the debits and credits created in the daybook transactions.
The list of "Negro births" pertains to Dr. Williams' approximately forty slaves and includes the mother's first name, the date of birth (the earliest being 1775) and, for many of them, the date of death. Several entries give the date the slave was sold.
