‎First edition of Bolton's discussion on how to place the newly found Zoophytes in the Linnean system, is it animal or plant, does the genus belongs to zoology or botany ?. In a previous letter to Linné the same year he tells him, that he intends to publish a work on a new zoophyte and ask for permission to dedicate it to Linné as a token of his high esteem.‎
