as to make noteworthy contributions to the 

 science of industrial hygiene. Dr. T. M. 

 Legge's section on Arsenic Poisoning is the 

 best brief treatment of this subject known to 

 the reviewer. Dr. E. E. Hayhurst's discussion 

 of brass and zinc poisoning, Dr. G. L. Apfel- 

 bach's treatment of carbon monoxid poisoning, 

 Dr. Hamilton's review of lead poisoning in the 

 United States and Dr. Louis Casamajor's sec- 

 tion on manganese poisoning all embody in 

 compact form original researches of the 

 authors which have been made imder Amer- 

 ican conditions and with such thoroughness as 

 to be of substantial and permanent value. 

 Professor P. S. Lee's chapter on Fatigue and 

 Occupation is a notable contribution to the 

 subject, and Dr. J. T. Bowen's discussion of 

 occupational affections of the skin contains 

 much valuable material. Dr. L. Devoto's ac- 

 count of his famous clinic for occupational 

 diseases at Milan, Professor G. C. Whipple's 

 brief discussion of the use and the fallacies of 

 statistics, and the sections on factory legisla- 

 tion by Mr. John B. Andrews, by the late 

 Professor C. E. Henderson and by Mr. 0. H. 

 Crownhart, are deserving of specially favor- 

 able mention. 



With the virtues of an encyclopedic work 

 prepared by many authors there necessarily 

 goes a certain lack of balance and proportion, 

 aggravated in this ease by the somewhat arti- 

 ficial separation of the diseases themselves 

 from their etiology and prophylaxis which 

 leads to the discussion of arsenic poisoning, 

 brass poisoning, etc., in two different places 

 in the book and often by different authors, 

 with some consequent repetition and confu- 

 sion. The sections on etiology and prophy- 

 laxis, as a whole, show a painstaking study of 

 the literature but do not suggest an intimate 

 first-hand contact with the inside of a factory. 



Perhaps the most striking evidence of this 

 academic attitude is the small amount of space 

 devoted to dust, ventilation and general factory 

 sanitation as compared with the industrial poi- 

 sons. The most serious problems of industrial 

 life are accidents and tuberculosis, the indus- 

 trial poisonings (except plumbism) being by 

 comparison relatively unimportant. Accidents 



presumably fall outside the scope of this work 

 but certainly industrial tuberculosis does not; 

 yet dust removal and factory ventilation are 

 scantily treated, while pages are devoted to 

 rare intoxications, of interest only as medical 

 curiosities. 



Dr. Gilman Thompson's " Occupational Dis- 

 eases " while preeminently medical in its view- 

 point, includes excellent chapters on factory 

 sanitation and dust removal, is in general far 

 better balanced and should prove more valu- 

 able for the physician and the average 

 worker in industrial hygiene; Dr. Price's 

 " Modern Factory," while much more ele- 

 mentary and necessarily superficial in certain 

 details, gives by far the clearest picture for 

 beginning students of the entire subject, in- 

 cluding accident prevention, and remains the 

 best text-book for social workers, factory 

 superintendents and others who may be inter- 

 ested in the general aspects of the question. 

 " Diseases of Occupation and Vocational Hy- 

 giene " contains much material which will 

 make it a valuable reference book for the 

 specialist; but it is not likely to supplant 

 either of the two earlier works, each of which 

 so well fills its special field.

The Origin of Veins of the Ashestiform 

 Minerals: Stephen Taber, Department of Geol- 

 ogy, University of South Carolina. Cross- 

 fiber veins are formed through a process of 

 lateral secretion; the fibrous structure is to be 

 attributed largely to the mechanical limita- 

 tion of crystal growth through the addition of 

 new material in only one direction. 



A New Test of the Subsidence Theory of 

 Coral Reefs: Eeginald A. Daly, Department 

 of Geology and Geography, Harvard Univer- 

 sity. Existing coral reefs are new upgrowths 

 on platforms which have been formed before, 

 and independently of, the reefs. The sub-
