Winter Botany, by Prof. Trelease (price 2S 50, postpaid) is 

 published by the author at Urbana, Illinois, and is described on the 

 title-page as "a companion volume" to his Plant Materials of 

 Decorative Gardening, which we have not seen. In this, we learn 

 from the introduction, " an unusually full account was given of 

 characters that are not mentioned in the usual handbooks, but the 

 keys were based in large part on differences used by the old herbalists — 

 position and other peculiarities of the foliage : the key of the present 

 volume utilizes leaf-scar and bud differences in the same manner." 

 It is a well-printed well-arranged book; there is a full description 

 of each genus, with illustrations of the characters above indicated, 

 followed by a clavis of the species : of the genera themselves a pre- 

 liminary key is given. Beferences are made to the works, of which 

 a bibliography is given, in which the " winter-character " is stated ; 

 " questions of nomenclature are waived " — the American practice of 

 trinominals is followed ; useful information is introduced, and there 

 is a glossary, followed by an index. The book is a model of concise- 

 ness and of a size convenient for the pocket. 



The part of The Essex Naturalist published in October contains 

 the interesting presidential address " On the Haunts of the Myce- 

 tozoa," delivered by Miss Lister in April last, and the conclusion of 

 her history of their study in Britain, to which is added a list of the 

 species found in Essex ; an excellent paper on the Ecology of Lichens, 

 with special reference to Epping Forest, by Mr. II. Paulson ; and 

 "some local anecdotes and reminiscences " of E. G. Varenne (1811- 

 87) by Alfred Hills, which — in view of Mr. Boulger's biography 

 already published in the E. Naturalist, of the present shortage of 

 paper, and of the very trivial and not always edifying natui'e of the 

 " reminiscences " — we are surprised that the editors should have 

 considered worthy of publication : we have seldom seen nine pages 

 less usefully occupied. 



At the meeting of the Linnean Society on Nov. 7 there was 

 read a paper by the late Prof. Arber and Mr. F. W. Law field on the
