- The New Zealand government sets aside Resolution Island in Fiordland as a nature reserve.[1]
- The New York Botanical Garden is founded in The Bronx largely due to the efforts of Nathaniel Lord Britton.
- Jane Willis Kirkaldy and Catherine Pollard become the first women to sit final examinations in biology at the University of Oxford (and achieve first class honours).[2]
Chemistry
- Agnes Pockels first publishes the results of her researches into surface tension.[3][4]
- The Fischer projection is devised by German chemist Hermann Emil Fischer,
Geology
