This volume was compiled in Egypt, where Gliddon lived for 23 years, and was copied from his original manuscripts for Samuel G. Morton by Edward M. Kern in Philadelphia in 1842. It includes drawings and illustrations.

The first fifteen volumes of these "Notes of Travel" are Lea's account of his trips to Europe during 1832 and 1852-1853. He met with naturalists, scientists, and did much sightseeing in England, France, Germany, Italy, and Austria. He records in detail visits and discussions with scientists, and makes sketches of many of the places he saw, particularly the Rhine River. The sixteenth volume is a memorandum book, 1853, containing accounts and expenses while in Europe.

This diary records the travels of Loammi Baldwin in the Netherlands (then including Belgium), England, and France, with detailed observations and careful pen-and-ink sketches of canals and canal machinery.
