Aquatic Plants of Iowa.— R. I. Cratty has published in the 

 Bulletin of the Laboratories of Natural Science of the University of 

 Iowa (Vol. Ill, No. 4) some " Notes on the Aquatic Phenogams of 

 Iowa," which will be useful in recording the past and present distribu- 

 tion of plants which are fast disappearing. It is a pity that author 

 and editor permitted the antiquated spelling of Phanerogam to be 

 used. There can be no valid excuse for " Phenogam." The species 

 noted are Arisaema triphyllum, A. dracontium, Symplocarpus fcetidus, 

 Acorus calamus, Lemna minor, L.trindca, L. polyrrhizu, Woftfia hra- 

 ziUmsi*, Tupha httifofia, Spn-goxhon simp!,,,; $. andmeladum, S. eury-

Another Elementary Botany. — Professor MacBride has re- 

 cently brought out a little book on botany for secondary schools, under 

 the title of " Lessons in Elementary Botany," issued by the house of 

 Allyn and Bacon of Boston. The author presents in small space es- 

 sentially that phase of botany with which we have long been familiar 

 in Gray's " Lessons," Miss Voumans's " First Book," " Second Book " 

 and "Descriptive Botany," and Wood and Steele's "Fourteen 

 Weeks in Botany." Whatever merits and demerits these works have 

 are here reproduced, somewhat modified of course. The lessons begin 

 with " buds," followed by " stems," " roots," " the leaf," " inflores- 

 cence," " the flower," " the fruit and seed." These topics occupy about 

 eighty-five pages, and while the subject matter is essentially similar to 

 that in Gray's " Lessons," the treatment resembles that of Youmans's 

 books, considerably simplified. The pupil is required to work out the
