account of the tertiary flora of Java, with a Hst of 38 species all 

 marked as new. Dr. Ettingshausen has published a finely illustrated 

 memoir on the Fossil Flora of the Monte Promina in Dalmatia, mainly 

 of an eocene character. Out of 4.5 species enumerated, one is con- 

 sidered .identical with a Sheppey species. Leaves referred to Pro- 

 teacese and to tropical Leguminosee and Laurinese are among the 

 more curious forms. But the objections I have made to the definitelj^ 

 naming of fragments must be held good against all these papers, and 

 to the extensive and in many respects highly valuable memoir of 

 M. Heer upon the tertiary flora cf Switzerland. 



Dr. Ettingshausen has made the tertiary flora of Haring in the 

 l^rol the subject of a finely illustrated and elaborate monograph, one 

 of the many beautifully got-up scientific publications that have of late 

 been issued at the cost of the Austrian government. He describes 

 no fewer than 180 so-called 'species,' or, more properly speaking, 

 portions apparently of different plants. Of these 73 are common to 

 the floras of other localities; out of this number 41 are eocene, 9 

 miocene, and 23 species common to eocene and miocene. Proteacese, 

 Myrtacese, and Leguminosse form as much as a third part of this 

 flora. The Flabellarise and Chamsecyparites remind us of certain 

 eocene plants of the Hampshire basin. Compared with existing 

 floras the general aspect is Australian. The author infers that the 

 climate was tropical, and ventures to pronounce on the probable mean 

 annual temperature of the region in which these plants lived, deter- 

 mining it to be 18° to 21° Reaumur. In this conclusion, as well as 

 in the decisions about species and genera, there is a degree of over- 

 precision assumed to which fossil botany can justly lay no claim. In 

 a previously published memoir on the tertiary flora of the A^'ienna 

 basin, the age of the latter is stated to be miocene and the climate 

 subtropical. In these determinations scarcely sufficient allowance is 

 made for difference of locality and A-arying conditions, such as time 

 of year of deposit and local elevation. The botanical diff'erences be- 

 tween the plant-bearing beds of our own eocenes might lead to con- 

 flicting conclusions were we not well acquainted with their geological 

 affinities. 



M. de Zigno has announced the discovery of a new locality in the 

 Vicentin for fossil fishes of the Monte Bolca type, and a rich tertiary 

 flora probably of somewhat later age. Of greater consequence and 

 general geological interest are his investigations in a stratum of grey 

 Jurassic limestone containing vegetable remains at JNIonte Spitz de 

 Botzo in the Sette commune of the Vicentin, first indicated by Fortis 

 towards the close of the last century. The bed lies ujjon oolitic 

 strata containmg Terehratula sjjherotdalis, and is covered by others 

 containing Ammonites athleta and viator, Terehratvla diplvja, and 

 other organic remains indicative of the horizon of our Oxford clay 

 and Kelloway's rock. M. de Zigno regards the plant-bearing bed as 

 the equivalent of the Great Oolite, or thereabouts. He has obtained 

 more than 400 sjiecimcns from the localities where it appears. All 

 the plants are of terrestrial origin, and bear the strongest analogy to 

 the oolitic floras of Scarborough and INIamers. The number of spe-
