of Canada, with a Relief Map of North America." This is on a scale 

 of 200 miles to an inch, and shows elevations at 100, 1000, 5000, 

 10,000, and above 10,000 feet, and does not seem to be generally 

 known. 



10. Pkimitive Fossil Fishes. — M. Ad. Kemna contributes to 

 the Bull. Soc. Beige Geol., xvii, 1903 (1904), a general i-evievv of 

 recent discoveries in fossil fishes of the earliest period. The writer 

 bases his review on the papers of Dr. Traqiiair and Dr. Smith 

 Woodward, and after pointing out the importance of the more 

 ancient fishes, refers to their zoological position, and sketches in 

 «oiiie detail the families Heterostracidee, Osteostracidae, and Anaspidse. 



11. Excursions in Belgium. — M. Eutot has provided a full report 

 of the excursion of the Belgian Society of Geology, Palaeontology, 

 and Hydrology to Hainaut and the environs of Brussels in 1902. 

 It is published in the Bulletin, xvii (5), 1904. The district traversed 

 was from Erguelinnes to Leval - Trahegnies, Mous, Vaulx lez- 

 Tournai, Blaton and Hautrage, Brussels and environs ; and the 

 jaded British geologist might do worse than spend his four days 

 over this ground. The geology covers the Landenian, Bruxellian, 

 Ypresian, and Montian, and fossils are abundant. 



12. Oligocene of Poland.--M. K. Wojcik has found in a small 

 valley in Kruhel Maly, near Przemysl, on the northern border of the 

 Middle Carpathians, a dark clay or sandy clay-bed with Mollusca and 

 Foraminifera. Of the forms found 46 out of 60 belong to the Lower 

 Oligocene of North Germany, as described by Von Koenen, and 

 8 of the 14 remaining species are found in the Vicentinian beds 

 described by Fuchs and Oppenheim. The whole fauna is com- 

 parable to that of the Clavulina szaboi beds of Von Hantken. 

 Accompanying the paper, which appears in the Bull, intern. Ac. Sci. 

 Cracovie, 1893, No. 10, are two plates of shells and Foraminifera. 



13. Minerals of Colombia. — A new journal has reached us 

 from the Eepublic of Colombia, "Trabajos de la Oficina de Historia 

 Natural," Bogata, 1904. This tract of 27 pages contains an account 

 of the alkaline and earthy minerals of Colombia, by Kicardo Lleras 

 Codazzi, chief of the section of Mineralogy and Geology. 



14. Cinnabar from Peru. — Augusto F. Umlauff publishes in the 

 seventh "Boletin del Cuerpo Ingenieros de Minas del Peru" a long 

 account of the Huan Cavelica mercury deposits, with map and 

 sections. The ore seems to occur indiscriminately throughout the 

 mass, as at Santa Barbara it is described and figured as occurring 

 in Andesites, Amphibolites, Basalts, Sandstones, Limestones with 

 Oretaceous mollusca, and Conglomerates. No description of the 

 fossils is given ; it being merely stated " molluscs and others very 

 abundant." 



15. 'Exotic Blocks' of the Himalayas. — In theComptesEendus 

 of the Ninth Congress of Geologists held at Vienna in 1903, just 

 published, we find Dr. C. L. Griesbach's note on the ' exotic blocks ' 

 of the Himalayas. These are masses of limestones of Nummulitic
