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 individuals and sights that he saw while in England. There are many observations of life in London, e.g. parks, buildings, paintings, food. Outside of London he visited many towns, including Manchester and its cotton mills as well as the steel mills of Birmingham. He relates his visit to Drury Lane and the dramatic performance of Sarah Siddons. Some of the people he met included Sir Joseph Banks, Sir Charles Blagden, Matthew Boulton, Joseph Priestley, William Pitt the Younger, and Benjamin Vaughan. He also visited and described the gardens at Kew. The diary includes several sketches, including the plan of Blenheim Palace, and also a table of distances traveled.

These two diaries were kept by Amelia Smith Calvert on trips to Europe with her husband Philip Powell Calvert. They record little scientific information, although there is mention of some of the entomologists and scientists whom they met (e.g. Professor Robert Newstead of University of Liverpool). In general, her observations are those of a literate and passionate sightseer who records travel events in great detail. The British diary (1912) includes descriptions of Liverpool, Edinburgh, York, Lincoln, Cambridge, Oxford, and London, and observations of the entomological specimens they saw in London. The Europe diary (1929) includes descriptions of Antwerp, Brussels, Amsterdam, Lucerne, Venice (of particular interest), Padua, and Milan. There is a description of P.P. Calvert's examination of insect specimens in the collection of Baron de Sélys-Longchamps in the Institut royal des sciences naturelles de Belgique.

This set of journals, copied legibly but with many excisions into the last volume, 914 Sm61, is from a tour of Germany, Denmark, Sweden, France, and England, to inspect technological improvements in manufacturing and mining. There are accounts of visits with C.D. Ebeling, Friedrich Klopstock, J.A.J. Reimarus, Anders Sparmann, and Karl P. Thunberg. Smith bequeathed this journal to the American Philosophical Society with the request that it be published if found to contain information "useful to the manufactories of my country."

Dalton Dorr (1846-1901) was the curator, secretary and director of the Pennsylvania Museum and School of Industrial Art in Philadelphia, the forerunner of the Philadelphia Museum of Art, from 1880-1899. A journal, written in 1897, copied from his notes and from memory, of travels in Greenland (1869), the Indian Territory, Colorado and the Pacific coast (1872-73); Paris, England, Scotland, and Ireland (1882-85), with some sketches. He took the Greenland cruise with Isaac I. Hayes in 1869, which was described by Hayes in his "Land of Desolation" (New York: Harper, 1872). See also, a companion volume of albumen prints taken by William Bradford and other members of "Under the midnight sun: a pleasure cruise in Greenland" in the summer of 1869.

This correspondence is principally concerned with business between Pershouse and his brother James in England, with comments on conditions and events in the United States, including anti-British feeling, Thomas Paine's return to America, Jefferson's administration, and immigration. The papers include Pershouse's journal (1800-1838), which includes accounts of travels in England, France, and the United States, letterbooks (1836-1862) of Henry Pershouse, nephew of John, chiefly on business matters, and two volumes of Pershouse genealogical data, compiled by B.M. Pershouse Bayley (1899).

This collection includes letters, diaries, notebooks, and early photographs, relating primarily to the Wister family of Germantown and Philadelphia. Much of the correspondence concerns domestic news and consists of letters from or to Sarah Wister. These include interesting observations on Germantown and Philadelphia society from other families as well, such as the Bayntons and Bullocks. There are numerous letters from various Wisters, including Casper, Charles Jones, Elizabeth (including a journal of a trip to Bristol, 1783), Hannah, John, Owen Jones, and others. There is also poetry by Sarah.

Robert Cushman Murphy (1887-1973), one of the twentieth century's great ornithologists, was curator of mammals and birds at the Brooklyn Museum (1911-1917) and was curator of birds and later chairman of birds at the American Museum of Natural History (1917-1973). The world's foremost authority on sea birds, in 1936, he penned Oceanic Birds of South America, a two volume set. An ardent traveler and explorer, he kept copious notes of his travels, which he typed up, illustrated and had bound. The APS library owns forty-two bound journals. Murphy was made an APS member in 1946. A pioneer in the study of the ecology, a louse, fish, plant, lizard, an Antarctic inlet, spider, and two mountains have acquired his name. This collection contains diaries, journals, articles, addresses and observations of Murph;, generously illustrated with newspaper clippings, photographs, letters, sketches, maps, and charts.
