— Garden and Forest for November, 1896, contains an article 

 on Di yopteris simulata, by Mr. George E. Davenport, with a 

 full-page plate of the fern drawn by Mr. C. E. Faxon. 



— The initial number of the Natiohal Science Journal has just 

 been issued at New Bedford, Mass. This publication starts with 

 a very creditable appearance and contains articles on entomology, 

 botany, mineralogy, anthropology, conchology, etc. Each num- 

 ber is to contain twenty- four pages An article on "Fern 

 Spores" appears in the current number. 



— The Transformation of Sporophyllary to Vegetative Or- 

 gans,'' by Prof. Geo. F. Atkinson, has been received from the 

 author. This is reprinted from Biological Lectures delivered at 

 Woods Holl in 1895. and details Prof. Atkinson's experiments 

 with Onoclea sen.^ibilis and O. Struthiopteris with reference to 

 changing fertile fronds to vegetative organs by cutting off the 

 sterile fronds. It is proved that the intermediate fronds occa- 

 sionally found on these species may be produced at will by re- 

 moving the sterile fronds early in the season. Eight plates, 

 showing the more striking forms developed, are included. 



—A most important contribution to the literature of American 

 botany has recently appeared in the shape of the first volume of 



An Illustrated Flora of the Northern United States and Canada,' ' 

 by Dr. N. L. Britton and Hon. Addison Brown. The authors of 

 this work have attempted the great task of -representing every 

 species in the territory covered, by accurate drawings, and have 

 also added concise and full descriptions for their identification. 

 Other points that make the work of value are the excellent Keys 

 to the Genera and Species, the Synonymy of each species and the 

 common names that are given. The nomenclature is also brought 

 up to date. The present volume contains 625 Royal octavo pages 

 with 1425 illustrations Among the families included are the 

 ferns, conifers, sedges, rushes, grasses, orchids, lilies, willows, 

 pond -weeds, etc. Two more volumes of like size will be issued 

 sometime this year, completing the work. Some idea of the es- 

 timation in which this work is held by botanists may be gleaned 

 from the fact that in less than six months nearly two thousand 

 copies have been sold We can supply the first volume, bound in 

 cloth, for $3.25. and will give a year's subscription to the Ferx 

 Bulletin with every order. Those who are now subscribers 

 may have their time extended one year with each order. Address 

 the editor of this journal.
