writes that he is pleased to know that Linnaeus has found the material sent to him of interest and that he would very much like to meet Linnaeus either in Stockholm or in Uppsala. af Bjerkén writes that he himself has caught Priapus alive. Its morphology varies, obviously we have more than one species. He has not seen any Microcosmus, but he can describe it from another’s description. af Bjerkén writes that Linnaeus can keep two of the most intact priapies and he asks Linnaeus to return the others. In one of the bottles sent, there were three water-insects, which Linnaeus did not know of, and he compares them with somthing he read in Patrick Browne’sBrowne, Patrick (1720-1790).
