5. Wisconsin Geological and Natural History Survey, E. A. 

 Birge, Director. — The Wisconsin Survey has recently issued four 

 road pamphlets, of 24 to 54 pages each, by the Highway Engi- 

 neer, A. R. Hirst. The topics discussed are : Earth roads, Stone 

 and Gravel Roads, the Earth Road drag, and Culverts and Bridges. 



6. Geological Map of Cape of Good Hope: — Four new 

 sheets of the Geological Map, by A. W. Rogers and A. L. Du 

 Toit, have been issued. No. 42 covers the region between 

 Kimberley and Hopetown, and No. 52 an area from Mafeking 

 westward to longitude 24° and from the Molopo river southward 

 to latitude 26° 30'. No. 49 is the Kuruman and No. 50 the 

 Vryburg sheet. n. e. g. 



7. Variations Periodiques des Glaciers, Xllme Rapport, 

 1906 ; par Dr. Ed. Bruckner et E. Muret. Extrait des Annates 

 de Glaciologie ii, March, 1908, pp. 161-198. (Freres Borntrae- 

 ger !Editeurs). Berlin, 1908. Also Zeitschrift filr Gletscher- 

 kunde; Band II, Heft 3, pp. 161-234. Berlin, 1908.— The report 

 on glaciers for 1906 presents facts similar to those of the last 

 live years. In the eastern Alps, of twenty-six glaciers reported 

 three remained stationary and one was advancing. The Italian 

 glaciers are all in retreat, and in Savoy and in the Pyrenees many 

 small glaciers and even certain neve fields have disappeared. In 

 the Bukhara mountains one glacier in the Pierre le Grand chain 

 has a marked advance. In the glaciers of North America there 

 has been a decided shrinkage, with the exception of the remark- 

 able glacier in Yakutat Bay, described by Tarr. h. e. g. 



8. The Ceratopsia ; by John B. Hatcher, based on prelimin- 

 ary studies by Othniel C. Marsh. Edited and completed by 

 Richard S. Lull. Monograph XLIX, IT. S. Geological Survey, 

 pp. 198, pis. 51, and 125 figures in the text. Washington, 1898. — 

 This volume constitutes the third of six extensive monographs 

 planned by the late Professor O. C. Marsh on the extinct verte- 

 brates of North America. One, on the Odontornithes, or toothed 

 birds, was published in 1880 ; a second on huge horned mammals, 

 the Dinocerata, in 1 884, while the present volume on the horned 

 dinosaurs has just appeared. The remaining three are in course 

 of preparation. 



Under Professor Marsh's direction, many of the illustrations 

 for these volumes were made both lithographic and on wood, and 

 a series of preliminary notices, largely descriptions of new species, 

 were published from time to time in this Journal. In the present 

 instance, the notices were 16 in number, the lithographic plates 

 19, while of the woodcuts there were 28. 



After Professor Marsh's death, in 1899, Professor H. F. Osborn, 

 who succeeded the former as Vertebrate Paleontologist to the 

 U. S. Geological Survey, assigned the Ceratopsia volume to Mr. J. 

 B. Hatcher, the discoverer and chief collector of this remarkable 

 group of reptiles. Hatcher in turn carried the work forward, add- 

 ing many of the remaining text-figures and plates as well as 15V 

 printed pages of the text. After having completed the morphol- 

 ogy and specific descriptions, Mr. Hatcher died on July 3, 1904, 

 and it became necessary for a third author to pick up the threads
