A young physician wrote most of this diary while a passenger on a voyage from Alexandria, Virginia, to Boston, Massachusetts, in 1846. Content includes humorous accounts of sailing by river and ocean, sailors' superstitions (i.e., Mother Carey's Chickens, also known as Storm Petrels, St. Elmo's Fire, etc.), weather and storm patterns, personal health, and patient treatment.
His humor often took the form of comical comparisons and exaggerations or plays on dialect. To entertain himself, he brought several books: Blackstone's Commentaries on the Laws of England, by William Blackstone, the Bible, and a pocket Shakespeare. He attached varying levels of reading intensity to each, as well as the applicable situation in which he might read them—Blackstone's Commentaries, for example, was "suitable for a listless, languid frame of mind" (page 6).
He brought with him two Bologna sausages, which he jokingly and emphatically mistook for a woman's bustle in an expression of his apparent hatred for the garment (pages 6-7). When he had to throw the spoiled sausages overboard several days later, he lamented that he couldn't do the same with every bustle in the land (pages 23-24).
The author and several others (the captain, a skipper, and officers from a nearby revenue cutter) briefly disembarked to visit a family's farm in Virginia while waiting for better winds to sail. He included racial epithets that the family used when he quoted their complaints about the labor involved in caring for their farm without enslaved workers (page 22). The skipper revealed that the author was a physician, whereupon he was entreated to care for several members of the family. The mother's eye had been "eaten out by cancer" and the young daughter had a hard lump on her nose that the family felt sure would turn into cancer. The author treated the daughter's nose by excising the lump.
At some point between Washington, D.C., and Alexandria, the author wrote of being "assaulted, battered, and robbed" by bedbugs, which led him to construct a makeshift bed of camp stools to sleep on to avoid being bitten at night (page 11). His rheumatism also caused significant discomfort during the trip, and a self-administered treatment of liniment did little to ease his symptoms (page 34). Although the physician questioned whether or not he would become seasick at some point during the voyage, he narrowly avoided it—he did, however, treat a fellow passenger with a course of "consolation [and] pills" (page 30) after the man became seasick and vomited over the fresh paint sailors were applying to the bulwarks and rigging.
The entries from page 46 onwards were most likely written after the author landed in Boston. He wrote about his plans to attend a series of lectures given by Prof. Agassiz [Louis Agassiz] on animal classification.
