In a letter to the American Geographical and Statistical Society, first Smithsonian Secretary Joseph Henry endorses Isaac Israel Hayes' expedition to the Arctic, which launches in July 1860. Henry and Smithsonian Assistant Secretary Spencer Fullerton Baird provide magnetic and meteorological instruments for the expedition, along with a dredge and collecting equipment for organic specimens. Hayes collects two thousand plant specimens, two hundred bird skins, and live fish for the Smithsonian's tanks. Upon his return, he gives a lecture at the Smithsonian on the expedition. In 1867, Hayes' "Physical Observations in the Arctic Seas" is published in volume 15 of Smithsonian Contributions to Knowledge.
