Geology and Mineralogy. 73 



some recent geological publications; and,, following, the names 

 and addresses of tbe geologists and mineralogists of the world. 

 It is a very convenient office companion for all workers in geology 

 and mineralogy. The American part is evidently made up from 

 Cassino's excellent "International Scientist's Directory," but with 

 omissions often of initials and an occasional oversight, that may 

 easily be corrected in another year's issue of the work. 



10. Chlamydoselachus anguineus Garm., a ' living species of 

 Cladodont /Shark; by S. Garm an. Bull. Mus. Com p. Geol. 

 Cambridge, vol. xii, No. 1, July, 1885. — This fine memoir of 

 special geological as well as zoological interest is illustrated by 

 20 plates. 



11. South Carolina : Resources and population, institutions and 

 industries. Published by the State Board of Agriculture ; A. P. 

 Butler, Commissioner. Charleston, 1885. (8vo, pp. viii + 

 726 + 20 unnumbered, 1 plate, 2 folding tables, map 27x34 

 inches.) — The State is divided into seven " agricultural and phys- 

 ical regions," viz : I, the Coast region, II, the Lower Pine belt, or 

 Savannah region, III, the Upper Pine belt or Central Colton belt, 

 IV, the Red Hills, V, the Sand Hills, VI, the Piedmont region, 

 and VII, the Alpine region ; and the topography, geology, and 

 agricultural capabilities of each are briefly described. The geo- 

 logic matter is mainly a compilation of well-known facts and prin- 

 ciples from the publication of Tuomey, Bieber, Ruffin and others, 

 but some observations and applications are apparently original. 

 Thus not only is Kerr's generalization of the southward deflection 

 of the North Carolina rivers extended to South Carolina, but it 

 is stated that the coastal islands are triangular, with the apex 

 "directed southwest, often terminating in marshes, while tbe 

 higher and drier base faces northeast," and that in the coastal 

 inlets the "ship channels are always found to 'the south of • the 

 harbors." The map (10 miles : J inch) exhibits, by means of colors 

 and black boundary lines, the fresh water swamps and salt 

 marshes, the two pine belts, the Red Hill and Sand Hill regions, 

 the northern limits of Pliocene, Ashley and Cooper (Eocene), 

 Santee (Eocene), and Cretaceous marls, the Buhrstone (Eocene), 

 formation, and the different lithologic phases of the " Hnronian," 

 " Laurentiau," and " Igneous" rocks. It is embellished by a crude 

 section from Charleston to Ridgeway. The volume contains lists 

 of vertebrate animals by F. W. True, of tbe invertebrate fauna 

 by L. O. Howard, and of the more common native and naturalized 

 plants by H. W. Ravenel, together with abstracts of meteoro- 

 logical observations, etc. w. J. mc g. 



12. Kobellite from Colorado. — Messrs. H. F. and H. A. Keixar 

 have recently given a description of a variety of Kobellite from 

 the mines of the Lilian Mining Co., inPrinterboy Hill, near Lead- 

 ville, Colorado. It occurs in nodules of various sizes up to sev- 

 eral feet in diameter ; they are usually more or less oxidized. 

 The fresh mineral has a fine-grained crystalline structure, a steel- 

 gray color and dark gray to black streak. Three analyses were 

 made with the following results :
