註釋Correspondence from German entomologist and physician Christian Rudolph Wilhelm Wiedemann (1770-1840) to American entomologist and conchologist Thomas Say (1787-1834), dated from 1819 to 1824. In a letter dated April 4, 1819, Wiedemann writes "it is my earnest wish to enter in correspondence with you, out of which, I am confident, there will issue some advantage to the study of natural history." He offers to send Say specimens of European insects and remarks on the impending publication of his Diptera exotica. Other correspondence relates to the further exchange of insect specimens and minerals, and the state of the entomology field in Germany. Wiedemann asks Say to send birdskins on behalf of the German entomologist and ornithologist Friedrich Boie (1789-1870), as well. After insects sent by Say arrived damaged, Wiedemann suggested in a letter dated December 12, 1821, that Say use a pincette to fasten the pins securing the specimens to wood or cork. Other topics include publications on entomology, and insect classification and description. Several letters include draft replies from Say, and there is also a list of insects for Wiedemann that Say observed on Major Stephen Harriman Long's (1784-1864) 1823 expedition to St. Peter's River. Also includes a receipt for insects and minerals shipped by Wiedemann through Ferdinand Schwartz.
