I love stumbling on interesting antique notebooks like this!

“Andrew Croswell (1778-1858) was a student at Harvard University in the late 1790s. He later studied medicine in Plymouth, MA, and practiced there and in Fayette and Mercer, ME. In the collections [at the Massachusetts Historical Society] we hold two notebooks that were kept by Croswell. The first is a mathematical notebook which contains definitions and problems in geometry, trigonometry, and surveying. The second is a physician’s notebook that contains notes on the treatment of diseases and injuries, as well as the use of some medicines.

The second notebook, relating to various diseases and treatments, is text-heavy in its content. Croswell – who had very nice, neat, and even handwriting – copied observations from published medical texts, especially the work of Dr. Benjamin Rush.”
