Captain William L. Hudson was commander of the US ship Peacock, one of the vessels of the United States Exploring Expedition to the Pacific, 1838-42, commanded by Commodore Charles Wilkes. He later transferred his flag to the Porpoise.

The journal begins when the expedition was en route from Fiji to Honolulu, and gives an account of the PEACOCK's visits to the Hawaiian Islands, Oregon, Southern California, the Line, Phoenix and Tokelau Islands, Samoa, the Ellice and Gilbert Islands (Tuvalu and Kiribati), and the wreck of the PEACOCK at the mouth of the Columbia River on the west coast of North America. After Hudson had transferred his flag to the USS PORPOISE, he crossed the Pacific to the Philippines, Sooloo Islands and Singapore. (The journal is a continuation of that filmed as PMB 146, which covers the Expedition's activities from 20 August 1838 to 8 August 1840)

Alden was an officer in the sloop-of-war 'Vincennes', the flagship of the United States Exploring Expedition which spent four years in the Pacific under the command of Commodore Charles Wilkes.

The journal gives an account - but not a day-by-day account - of the Vincennes voyage which took in the Tuamotu Archipelago, Tahiti, Samoa, Fiji, Australia, New Zealand, the Antarctic, Hawaii, the Gilbert (Kiribati), Ellice (Tuvalu) and Marshall Islands.

A catalogue of the ethnographic items collected by the United States Exploring Expedition to the Pacific (1838-42) led by Commodore Charles Wilkes. The Expedition visited the Tuamotu Islands, Tahiti (in French Polynesia), Samoa, Tonga, Fiji, Lord Howe Island, Australia, New Zealand/Aotearoa, Gilbert Islands (Kiribati), Marshall Islands, and Hawaii. The catalogue was prepared in 1846 by Titian Ramsay Peale, an artist-naturalist with the Expedition. A typescript version, prepared by the PMB, follows the original document on the microfilm. See also the Bureau's newsletter, Pambu, October-December 1971:25, pp. 4-7 and PMB MS 89 and MS 146.

Captain Edward Primrose Tregurtha (1803-1880) was born in Cornwall, UK, and died in Launceston, Tasmania. He went to sea at an early age, and made voyages to the Far East and India. In 1831-33, as master of the whaler Caroline, he made an extensive whaling voyage out of Hobart. His itinerary included Sydney, the Bay of Islands, the Kermadecs, Rotuma, Wallis Island, the Gilberts, Solomon Islands, New Ireland, and the Coral Sea. After a visit to England, Tregurtha returned to Tasmania, whence he traded with neighbouring colonies as owner and master of the Henry. He made voyages to Adelaide in 1837 and took early settlers and sheep to Port Phillip. He later opened a business in Launceston as a general merchant and shipping agent.

The autobiography, which, in many places, appears to have been written up from journals kept at sea, gives a full account of Tregurtha's life from his birth in 1803 until the late 1830's. From then until the year 1852, it is brief and sporadic.
