THE recent review by Prof. F. E. Fritsch1 of "A Forgotten History of Botany" by Karl F. W. Jessen has reminded me of another little-known book on the same subject, published in 1871 in Paris, under the signature of "L. G.". It is entitled "Precis de l'Histoire de la Botanique", and is one of the seventeen volumes of the botanical encyclopaedia "Le Regne Vegetal" published by a group of botanists of that period. The author of the "Precis" is perhaps the editor of the encyclopaedia, L. Guerin, whose name appears at the bottom of the title-page ; but this is merely a guess based on the initials which are used. The book seems to have been inspired mainly by Pritzel's first edition of "Thesaurus literaturae botanicae" (1851), but the "Precis" is stated to contain the titles of numerous publications unknown to Pritzel, especially French publications.
