perienced field student and collector. The book ought to be especially helpful 

 to high school and college botany teachers who include some field work in their 

 courses, as they should. And whereas, at present, the moss students in any one 

 state can, on the average, be counted on the fingers of one hand, Mrs. Dunham's 

 book is likely to increase them to hundreds. 



The book does not pretend to take up the pigmy genera like Archidium, 

 Astomum, Bruchia, Ephemerum, Micromitrium, Phascum, and Sphaerangium. 

 It even omits Ptychomitrium, Rhahdoweisia, Seligeria, Zygodon, Coscinodon, Dicra- 

 nodontium, and Dicranoweisia, genera represented by species in the geographic 

 area treated; still, the stimulus from it should be felt in every state east of the 

 Rocky Mountains. 



The typography is clear and excellent. The illustrations scattered through 

 the book are helpful to beginners. The accents for the frequently long technical 

 names are given with great fidelity to classical principles. However, I wish here 

 to correct two errors in accent. One is on page 156: Catharinaa needs to be 

 accented on the penult, because this is long, being a diphthong. The other is 

 on page 213: Drepanbcladus must get the accent on the antepenult, because the 

 "a" of the penult is short in quantity, as given in the Greek lexicons, in xXaBoq, 

 a shoot or branch. On page 220, the varietal name Mackayi ought by rights also 

 to be accented on the penult; but here usage has probably some claim to fix the 

 accent on the antepenult.

Mosses, in the Natural History of Madagascar 



By Renauld and Cardot 



"Histoire physique, naturelle et politique de Madagascar, publiee par A. et 

 G. Grandidier: Vol. xxxix. Mousses, par F. Renauld et J. Cardot. I vol. gr. in 

 4to, de 560 pages et atlas de 187 planches. Prix: 467 fr, 50. Librairie Hachette 

 et Cie., 79 boulevard St. Germain, Paris. " 



After the death of M. Renauld, M. Cardot was forced to continue this great 

 work alone, but fortunately it was finished a few weeks before the opening of the 

 war. In consequence of the outbreak of the war, the printing of the work which 

 was started near the close of 1913, has just been completed. The systematic 

 portion is preceded by two chapters dealing with the topography, climate, geol- 

 ogy and bryo-geography of Madagascar. The systematic portion itself includes 

 the description of nearly 550 species, of which more than half are endemic. Each 

 description is accompanied by the necessary synonomy, and by more or less ex- 

 tended critical notes. A rather large number of species are described for the 

 first time, as well as one new genus upon the authority of M. Cardot alone, since 

 it was only recognized after the death of his collaborator. In the 187 plates, 360 

 species are figured. 



Only 150 copies are placed on sale, 100 of which are reserved solely for the 

 subscribers to the complete work.
