telling the student what to see and expecting him to see it. In- 

 stead, after directing the student how to manipulate his material, 

 there is a series of questions in each paragraph which requires his 

 original investigation to answer. The author has gone into the 

 work most thoroughly, and the book should have a wide vogue 

 among teachers and students. 



The guides to our wildflowers continue to multiply, and one 

 of the best of recent works is F. Schuyler Matthews' "Field-book 

 of American Wild-flowers. "t This book has one merit that none 

 of the others possess, namely, its size, which adapts it for carry- 

 ing in the pocket. There are twenty-four plates in color and 200 

 full page illustrations in black and white by the author, in ad- 

 dition to descriptions of nearly five hundred characteristic wild- 

 flowers of the northeastern States. These descriptions are in 

 plain English, so far as the limitations of the subject permit, and 

 one will find interspersed with the descriptive matter many ob- 

 servations of interest. Special attention has been paid to the in- 

 sects which pollenate the different species. Being artist as well 

 as author, Mr. Matthews has attempted to name more correctly 

 the colors of our flowers, and his book will certainly be a refer- 

 ence book on this subject. The rest of the text is accurate and 

 conservative and will delight the rambler who goes afield with a 

 book in his pocket. 



Dr. D. T. MacDougal's "Experimental Plant Physiology," 

 issued in 1895, having gone out of print, the author has replaced 

 it with a volume entitled "Elementary Plant Physiology"t which 

 follows very much the lines of the earlier volume. Directions 

 are given for performing various experiments to show che 

 phenomena of growth, nutrition, respiration, etc.. etc. There a^e 

 108 illustrations. The experiments requiring to be made are such 

 as can be made with the cheapest and simplest apparatus.
