What was advertised in a colonial newspaper 250 years ago today?

“A Compleat Assortment of Druggs and Medicines; … a fine Assortment of Surgeon’s Instruments.”
Benjamin Church operated a shop that likely attracted many different kinds of customers.
Anderson’s Pills, Bateman’s Drops, Stoughton’s Bitters, and Turlington’s Balsam were all familiar patent medicines that colonists would have purchased both with or without consulting a physician. In some ways, they were the over the counter medications of their day. The first half of Church’s advertisement lists a “Compleat Assortment of Druggs and Medicines” and ingredients that customers from a variety of backgrounds would have purchased.
The second half, on the other hand, lists equipment, “a fine Assortment of Surgeon’s Instruments,” likely intended for specific occupational groups that practiced one form of medicine or another. Everyday consumers may have had some of these supplies in their homes, just as modern American households possess basic first aid materials, but “Midwifry Instruments” and “Surgeon’s Knives” were likely purchased almost exclusively by medical practitioners.
I’m curious to know which volumes were included among the “good Collection of modern Medical Authors.” Did they include any works of general reference? Who would have purchased them?
Overall, this advertisement offers an interesting glimpse of medicine in colonial America, but it also demonstrates how an eighteenth-century business operated. Once upon a time I worked for an independently owned retail pharmacy and home health care supply store. Although the two portions of the business shared a location, most employees were specifically affiliated with either one or the other. Pharmacy staff and home health care staff had distinct areas of expertise and experience and consulted with customers accordingly. In contrast, it is likely that Benjamin Church worked on both sides of the business at his shop in colonial Boston.
