John Henry Davies (1838-1909).*— H. W. Lett publishes an 

 obituary notice of J. H. Davies, a bryologist who spent most of his life 

 in Ireland. In 1857 he Yisited the Isle of Man, and compiled a list of 

 all the mosses he could find ; and he was an active member of the 

 Yorkshire Naturalists. During the next half-century he resided in 

 Ireland, and was busily engaged in some linen bleach-works. But 

 after retiring from work some few years ago he again reverted to the 

 study of mosses, and published some seven papers on new or rare mosses 

 collected in Ireland. 



A. Geheeb : Necrology. — T. Husnot t gives an obituary notice of 

 Adalbert Geheeb, born in 1842 at Geisa (Saxe Weimar), died September 

 190!). He succeeded to his father's pharmacy business in Geisa in 

 18G7, and carried it on for thirty years. From the year 1858 he 

 worked at bryology. He paid special attention to the moss-flora of the 

 Rhongebirge, but he also published or collaborated in several papers on 

 exotic mosses. His herbarium has been purchased by a friend and 

 presented to the Berlin Museum. 



J. Roll X writes a somewhat fuller notice of the same bryologist, and 

 adds a portrait of him taken in 1907. He gives a brief resume of his 

 chief bryological journeys, and of his various contributions to the 

 literature of mosses. Geheeb was artistic : he played the violin and 

 wrote poems ; he also prepared with great skill some landscapes com- 

 posed of mosses. As a collector he was distinguished for his great 

 powers of observation and his knowledge of the peculiarities of mosses 

 and of their habitats. 



Leo Lesquereux.§ — A. M. Smith publishes a biographical notice of 

 Leo Lescmereux (born 180G, died 1889). Born near Neufchatel, in 

 Switzerland, he devoted much time to the study of mosses and the forma- 

 tion of peat-bogs ; for a treatise on the latter he gained a gold medal 

 awarded by the Swiss Government. In 1S4.S he followed his friend 

 Agassiz to America, and soon began to co-operate with W. S. Sullivant 

 in Bryology. Together they published the Musci Americana Exsiccati, 

 the report on the mosses of Wilkes' South Pacific Exploring Expedition, 

 the Icones Muscorum, etc. Lesquereux also studied the coal formations 

 of the United States, publishing various reports and catalogues of the 

 plants of the Coal Measures. He collaborated with T. P. James in the 

 preparation of the Manual of American Mosses (1884).
