[N. S. Vol. XVII. No. 427. 



This voluminous work is from the brain 

 and pen, not of a teacher, but of the chief 

 chemist in the Great Northern Railway 

 Shops, St. Paul, and naturally reflects the 

 practical experience of its industrious author. 

 To attempt to review in a conscientious man- 

 ner a closely printed volume of more than six 

 hundred pages, estimated to contain over four 

 hundred thousand words, is impossible in the 

 time and space that can be given. The au- 

 thor states that the ' volume is intended for 

 the aid of students who have a fair acquaint- 

 ance with the elements of general chemistry 

 and can devote a limited time to quantitative 

 analysis concurrent with or following the 

 usual qualitative course.' At the same time 

 it will form ' an introduction to the mono- 

 graphs on special departments of technical 

 analysis for those purposing to engage in 

 some particular branch as a future occupa- 

 tion.' 



After outlining the general principles of the 

 subject and describing tte operations usually 

 employed, the book presents a graded series of 

 exercises for practice; these comprise twenty- 

 four examples of great diversity, alcohol, fer- 

 rous sulfate, coffee, cast iron, ether, vinegar, 

 hydrastis, metol, steel, barium chloride, lard, 

 air and woUastonite, with others, in the se- 

 quence here given. 



Then Part III. begins, at page 259, and 

 deals with the analytical behavior of articles 

 of commercial importance; these embrace, 

 among others, iron ores, coal, natural water, 

 fertilizers, alkaloids, tannins, carbohydrates, 

 soap, milk and butter, and urine, besides 

 methods based on colorimetry, electrolysis, 

 and organic analysis both proximate and ulti- 

 mate. 



Part IV., beginning at page 521, gives notes 

 and observations relating to the art in gen- 

 eral. The volume closes with an appendix on 

 ' Technical and Industrial Analysis,' and an 

 index. 



This work is in some degree encyclopedic; 

 the author shows familiarity with many 

 branches of the subject, and the numerous 

 citations show a wide knowledge of the litera- 

 ture, especially American. He has rescued 

 from the pages of periodicals many good 



methods little used in laboratories, giving 

 their authors due credit. He shows through- 

 out ability, thoughtfulness and universality. 

 The arrangement of some of the matter is 

 open to criticism. The book adopts the mod- 

 ern spelling of ' sulfur ' ; it is freely illus- 

 trated; its rather small type was probably 

 necessitated by its length; there are about 

 seven hundred words on each page. The 

 paper, type and binding are hardly up to the 

 high standard adopted for other works of like 

 character. 



This comprehensive treatise of Mr. Julian 

 contains many processes, as well as specific 

 details of ordinary methods, not easily found 

 elsewhere, and ought to be serviceable in the 

 libraries of technical schools and universities 

 as a work of reference. H. C. B.

 Gonionema.' 



A rgsumS of experiments conducted at the 

 Marine Biological Laboratory, Woods Holl, dur- 

 ing the summer of 1901, and extending the previ- 

 ous work of C. W. Hargitt and Morgan. 



2. C. W. Hargitt, ' Notes on a few Medusae new 

 to Woods Holl.' 



This paper is part of the synopsis of the medu- 

 soid fauna of the region which it is hoped may be 

 ready within the year. 



3. Walter S. Sutton, 'On the Morphology of 

 the Chromosome Group in Brachystola, magna.' 



The conclusion is that the association of paternal 

 and maternal chromosomes in pairs and their 

 subsequent separation during the reducing division 

 may constitute the physical basis of the Mendelian 

 law of heredity. This subject will be continued 

 in" a later number of the Bulletin.
