A previously unpublished letter by Leibniz on the geography of flooding has been published in Annals of Science with a commentary by Lloyd Strickland and Michael Church. Lloyd is a leading Leibniz scholar and Michael is one of the few physical geographers I know with a serious interest in the history of the discipline – he wrote a chapter for the Reading Kant’s Geography book I co-edited with Eduardo Mendieta. You can read my take on Leibniz’s relation to geography in Geographica Helvetica (open access).

The paper on Leibniz and flooding requires subscription, though the first fifty downloads are free, and I’m sure the authors would be pleased to send a copy to people interested beyond that.
