 1902. — The great Mino-Owari and other recent destructive earth- 

 quakes have given Dr. Omari the data necessary for an exhaus- 

 tive study of the "Deflection and Vibration of Railway Bridges " 

 (No. 9). Dr. Omari also continues the unfinished work of the 

 late Professor Sekiya, in a paper on " Macro-Seismic Measure- 

 ments in Tokyo" (Nos. 10 and 11). Professor Tanakadate 

 describes a "Vertical Motion Seismometer" (No. 7), and A. Ima- 

 mura the "Seismic Triangulation in Tokyo." 



5. Phycologia B or eali- Americana. Fasc. xix, xx ; by F. S. 

 Collins, W. A. Setchell and Isaac Holden. — This valuable 

 work now includes twenty fascicles comprising one thousand 

 numbers besides three fascicles of larger size with 75 numbers. 

 This series of algae exsiccate has never been surpassed in value 

 by any similar work, and, if we consider not only the large num- 

 ber of species issued, the excellence of the specimens themselves 

 and the remote and little explored regions from which in many 

 cases they were obtained, but also the accuracy of the determi- 

 nations and the detailed synonymy given on the labels, it is 

 doubtful whether the series has ever been equalled. Fasc. xix is 

 devoted to algae from our Pacific coast as far north as Alaska, 

 which were collected mainly by the botanists connected with the 

 University of California. There is a short preface by Prof. 

 Setchell describing the different regional divisions of the West 

 coast with notes on the collectors of algae on that coast. Besides 

 such novelties as Anatheca furcata and Fauchea Gardneri and 

 other characteristic western species, the series of species found 

 also in other regions is important for a comparative study. Fasc. 

 xx includes a new Pithophora varia Wittroch, Phizoclonium 

 erectum and Dichothrix rupicola, species recently described by 

 Collins, and an interesting set of marine Cladophorae and other 

 green algae. The Phycologia is indispensable to all who study 

 the algae of North America and the authors are to be congratu- 

 lated on the extent and high quality of their undertaking.

6. Fungus Diseases of /Stone-Fruit Trees in Australia and 

 their Treatment ; by D. McALpine. 165 pp., 54 pis. Melbourne, 

 1902. — Although the study of the plant-diseases of Australia is 

 of comparatively recent date, a number of important contribu- 

 tions to the subject have appeared in the last few years, the latest 

 being that of Prof. McAlpine of the Department of Agriculture 

 of Victoria. The volume, which is very fully illustrated, a num- 

 ber of the plates being colored, brings out the unpleasant 

 fact that, even in a country so remote from Europe and North 

 America as Australia, there is no exemption from the diseases 

 which infest older countries. The leaf-curl of peaches, the 

 prune-rust, the shot-hole disease and numerous others are pests in 

 Australia as well as with us. Nor, unfortunately, is Australia
