 (Hoernes) The Gastropoda and Pteropoda of the Tertiary hasin of Vienna; 

 with a map and fifty-two plates on India paper — pp. 736. Five hundred species, 

 one Pteropod Vaginella depressa, the rest Gastropoda, from nearly two hundred 

 different localities in this district are here figured, many of them in various 

 aspects and ages. The plates are beautiful specimens of Lithographic art. The 

 illustrations further comprehend a Latin diagnosis, the measurement after 

 D'Orbigny's method, the Synonyms in Chronological order, a particular enume- 

 ration of localities, and the description of the species in detail with especial 

 reference to living forms. The area of diffusion of every species is further 

 shown in one view, by means of a table of sixty-six columns, filled up for the 

 Tertiary Deposits elsewhere, which have been investigated hitherto.

Vol. I. ; with twenty-three plates. A.D. 1856. 

 (Bernard) Essay on the Pancreas, and function of the Pancreatic juice in the 

 digestive process, especially in the digestion of Adipose substances — p. 379- 

 563. (Derbes and Solier) Essay on some points of the physiology of Algae — 

 p. 1-120. The classification of Algae, based on the observed phenomena, is as 

 follows: — 1. Spores having motion (zoospores) : Antheridia none or undis- 

 covered. A. Zoospores produced in all the cells of the frond ; or in special 

 cells, but developed simultaneously with the others, and resembling them, or 

 more rarely differing in form. Fam. 1. Nostochineae : Nostoc, Sphaerozyga. 

 Fam. 2. Uivaceae : Tetraspora, Ulva, Colpomena. Fam. 3. Conferveae : Hy- 

 drodictyon, Hormiscia, Tribonema, Tiresias, Conferva, Chaetophora, Drapar- 

 naldia, Bretonia. B. Zoospores produced in particular and localised organs 

 (cystocarps) ; developed at a determinate period of the vegetation, a. Cysto- 

 carps in communication originally, and sometimes permanently, with the rest 

 of the frond. Fam. 5. Siphoneae: Bryopsis, Derbesia, Codium, Dasycladus, 

 Halymeda. d. Cystocarps separated, from the first, from the rest of the frond. 

 Fam. 4. Ectocarpeae : Ectocarpus, Sphacelaria, Giraudia. Fam. 6. Mesog- 

 loivae : Liebmannia, Stylophora, Castagnea, Nereia. 11. Spores destitute of 

 motion; Antheridia producing Antherozoids. A. Antherozoids furnished with 

 Endochrome. Fam. 7. Cutleruae : Cutleria. Fam. 8. Fucaceae : Cystoseira. 

 B. Antherozoids hyaline, a. Reproductive corpuscles produced in all the cells, 

 or in cells resembling those of the rest of the frond, and developed simulta- 

 neously with them. Fam. 9. Bangieae : Porphyra, Bangia, d. Reproductive 

 corpuscles produced in localised organs, which are developed at a determinate 

 period of the vegetation, a. Fruit capsular (poly spore); with a continuous 

 membranous coat Fam. 10. Delesserieae : Aglaophyllum. Fam. 11. Cera- 

 mieae : Callithamnion, Gnffithsia, Ceramium, Wrangelia. b. Polyspore with 

 a cellular coat. Fam. 12. Rhodomeleae : Polysphaeria, Rytiphlcea. Fam. 13. 

 Chondrieae : Laurencia, Bonnemaisonia.
