3© rnOCEEDINGS OF THE 



roua drift-travels of tlic Sierra Nevada ; " and Part i. of Heer's 

 ' Flora fossilis Grcculaudica.' 



Occupying a position by itself, I must next mention M. Alph. 

 de Candollc's ' L'Origine dcs Plautes cultiveea,' itself an cxpan- 

 siou of a portion of his ' Greographie botanique ' of nearly thirty 

 years before. 



The i)roductions ostensibly arising from Botanical Gardens 

 are the following : — The s-econd volume of Prof. Eichler's ' Jahr- 

 bueh des K. bot. Gartens zu Berlin,' in continuation of the volume 

 I cited last year ; Signer Todaro's ' Hortus botanicus Panormi- 

 tauus ' has entered upon a second volume, two fasciculi having 

 ap2)eared since I last spoke of the book ; Heer Treub has brought 

 out vol. iii. of the ' Annales du jardin botanique de Buitenzorg ;' 

 and M. Lavallee has issued the fifth livraison of his exquisitely 

 illustrated ' Arboi'ctum Segrezianum.' 



Turiiing to Vegetable Physiology, I would first remind you of 

 the publication of the second English edition of Sachs's ' Textbook 

 of Botany,' under the editorship of Dr. Vines. A portion of 

 Sachs's original work has been amplified by Dr. Goebel under the 

 title of ' Pfianzenmorphologie.' Sachs himself has edited Heft 4 

 of the second volume of ' Arbeiten des botanischen lustituts in 

 Wiirzburg ; ' and Pringshcim's ' Jahrbuch ' has continued to bring 

 papers of sterling value and interest before the botanical world. 

 Dr. E. Grassmann has brought out the second volume of the 

 boolv I mentioned at the last Anniversary, styling it ' Buch ii. Der 

 Lebeuslehre.' 



Of particular interest I may specially allude here to Mr. 

 Gardener's paper in the Proc. Koyal Society on the continuity of 

 Protoplasm in the motile orgnns of plants ; and to Mr. Hill- 

 house's observation on the intercellular connection of Protoplasm 

 — the latter essay being in German in the ' Botanisches Central- 

 blatt.' Herr Vcichting has published a treatise, ' Die Bewegun- 

 gen der Bliithen und Priichte,' at Bonn ; and Prof. Strasburger 

 has issued his furchur researches on the origin and growth of 

 the merabraue of the ceil, and the processes which precede the 

 division of the cell-nucleus. Dr. Herman Mueller has produced 

 lurther researches on the Fertilization of Flowers by Insects — 

 a topic which has been also handled at one of our own meetings 

 by Mi\ A. W. Bennett. Count Solms-Laubach has devoted 

 much attention to the process of Caprification and its antiquity. 

 It may De of interest here to remark that the first Italian trans- 

 lation of Mr. Darwin's classical ' Fertilization of Orchids ' has 

 just a])peared. Dr. Schmitz on the chromatophores of Algae, 

 and J. Moller's ' Anatomie der Baumeriuden ' may probably be 

 fitly introduced here ; and Mr. Penhal Ion's ' Tables for Students 

 and Beginners in Vegetable Histology ' leads me to the subject 

 of elementary books. 



Under this heading I may specify the fourth edition of Prof.
