Edward Perceval Wright.* — H. H. Dixon writes a note on the late 

 E. Perceval Wright, Professor of Botany at Trinity College, Dublin, for 

 thirty-five years, and Keeper of the Herbarium. He was born in 1834 

 in Dublin, was educated at home, and began life as a clerk in<a com- 

 mercial company at the age of sixteen. This post, however, he resigned 

 in 1853, and devoted himself to Natural Science, entering Trinity 

 College. In 1857 he took his degree, and was appointed Director of the 

 Museum in Trinity College. In 1858 he was appointed Lecturer in 

 Zoology in Trinity College, and Lecturer in Botany in Steeven's Hospital 

 Medical School. In 1862 he took his M.D. degree, and in a few years 

 he had made himself a position as oculist in Dublin. In 1865 he was, 

 however, appointed locum tenens for Harvey at Trinity College, and the 

 following year he gavei up his ophthalmic work. His various voyages 

 and travels gave him material for the publication of numerous reports 

 and papers, which were a valuable addition to botanical literature.

Studies in Fossil Ferns.f— D. H. Scott, in the second edition of 

 his Fossil Botany, adds much new matter, especially in connexion with 

 the Pteridospermae and Bennettiteaa. Two chapters are devoted to giving 

 a connected account of the Pteridospermae and the so-called Cycadofilices. 

 Another chapter treats of the Sphenopsida (including Equisetales, Pseudo- 

 borniales, Sphenophyllales, Psilotales), the Lycopsida (Lycopodiales), 

 and the Pteropsida (including Filicales, Pteridospermas, GymnospermaB, 

 Angiospennas). 



Zygopterideaa.J — T. Bertrand publishes a detailed account of the 

 Zygopterideas, treating of their anatomy as compared with that of the 

 Anachoropterideae and Botryopterideae, which contain one genus each. 

 He gives a systematic account of all the genera and species known in 

 the group. 



Stipes of the Fossil Asterochlaena.§ — P. Bertrand gives an account 

 of the general anatomical characters of the stipes of Aster ocMsena laxa 

 Stenzel, and lays special stress on the median bands of protoxylem. The 

 affinities of the plant are Clepzydropsis and Ankyropteris. Bertrand 

 briefly indicates the principal forms of fibro- vascular bundle in the stipes 

 of the Zygopterideae.
