4. La Science S'eismologique. Les Tr emblements de Terre par 

 le Comte de Montessus de Ballore, Directeur du Service seis- 

 mologique de la Republique dn Chili, avec une preface par M. 

 Ed. Suess. Pp. vii + 579, maps and figs. 222. Paris 1907 

 (Librairie Armand Colin). — This is a work of still wider scope 

 than the recent volume by the same author upon la Geographic 

 s'eismologique. The introduction consists of two chapters. The 

 first upon the present standing and tendencies of the science and 

 its two divisions, — the study of the nature of earthquake waves, 

 a. branch of physics; and the study of their causes and effects, a 

 branch of observational geology. The second introductory 

 chapter is on the history of seismology and indicates the extreme 

 i*ecency of the science as a subject of exact study and its present 

 increasingly great importance. 



The body of the work is divided into three portions, the first 

 being devoted to macroseisms, or perceptible earthquakes, the 

 second to microseisms and to instrumental or theoretic seismol- 

 ogy, the third to megaseisms, or destructive earthquakes, followed 

 by a discussion of means designed to minimize the disastrous 

 results. 



As is to be expected from this author, the work is one of great 

 value and completeness and will not fail to interest all students 

 of seismology. J. b. 



5. The Lotoer Paleozoic Fossils of the Northern Shan States, 

 Burma ; by F. R. Cowpee Reed, Mem. Geol. Surv. India, Pal. 

 Indica, New Series, ii, Mem. 3, 1906, pp. 154, pis. 8. — As yet 

 little is known of the older Paleozoic rocks of Asia, and it is 

 therefore very gratifying to find so much that is new in a recent 

 paper published by the Survey of India. 



Ordovician (Naungkangyi formation). From twenty localities 

 48 species have been obtained ; of these, 28 are specifically 

 named and 19 are restricted to Burma. The following are the 

 more important forms from a stratigraphic standpoint. Of the 

 Bohemian genus, Aristocystis, there is a new species ; of the 

 widely distributed European Heliocrinus 3 (new), and of Echi- 

 noencrinus 2 are compared with north European forms. The 

 genus Caryocrinus is said to be present in 3 new species, but 

 these seem to the reviewer to be nearer Hemicosmites in having 

 but three pairs of closely set brachioles, while the Silurian genus 

 has 13-14 in five widely separated bases. The Baltic Protocri- 

 nus is represented by a new form and Cyclorinus by a form near 

 C. sp>asski Eichwald. 



Of brachiopods, there are Rafinesquina imbrex Pander, R. 

 subdeltoideii (a new form closely related to American Trenton JR. 

 deltoidea). Orthis subcrateroides (a new JRafinesqui?ia near JR. 

 ■mini lesotaen sis but larger), Leptaena ledetensis (new, near L. 

 charlottae W. & S., of the Black river), Plectambonites quinque-
