CUsmiR de Caindolle.*- — The third generation of the celebrated 

 de Candolle family has passed away in the person of Anne- 

 Casimir-Pyramus de Candolle. Born at Geneva on the 20th 

 February, 1836, Casimir de Candolle commenced his scientific 

 studies in 1853 in the Faculty of Sciences, Paris, where he 

 devoted himself principally to chemistry, physics and mathe- 

 matics, and obtained in due course the degrees of B.esSc. and 

 L.esSc. 



He assisted his father, Alphonse, in editing the last two volumes 

 of the Prodromus, and was joint-editor with him oi the Mono- 

 graphiae Phanerogam-arum w r hich succeeded it. His first 

 taxonomic work was a revision of the Juglandaceae, which 

 appeared in the Prodromus, followed in 1869 by a revision of the 

 Piperaceae in the same work; his interest in the latter group 

 continued to the end of his life, and specimens of Piperaceae 

 were sent to him from oil parts of the world for determin it ion, 

 A monograph of the Meliaceae from his pen appeared in the 

 Monographiae P/ianerogamarum. 



Casimir de Candolle was interested in many other departments 



of botany, as is shown by the wide range of his published works. 



His mathematical bent found expression in a series of papers on 

 phyllotaxy. Amongst his anatomical contributions may be 

 mentioned a memoir on the comparative anatomy of the leaf in 

 some families of Dicotyledons, and his interest in systematic 



tnatomy no doubt led to the inclusion in the Monographiae 

 Phancrogamarum of Yesque's revision of the Gutti ferae, in which 



xtensive use is made of anatomical characters. His physiological 

 work included memoirs on t>he effect of low temperatures on the

Dr. J. Briquet has given a very interesting account of M. de Candolle's 

 work in Mem. Soc. Phys. Hist. Nat. Geneve, vol. xxxix. fasc. 2, pp. 89-98 

 <1919).
