reagents. This arrangement is a new one for works on this subject, 

 and is, we think, excellent. Turning to the important subject of 

 albuminuria, as an example, we find a fairly satisfactory article. 

 Functional albuminuria receives marked attention, and all the new 

 tests for albumin are considered and their value discussed. 



In addition to the ordinary methods, directions are given for 

 testing urine with tablets and test-papers. This will be a welcome 

 addition to those who wish to make use of these convenient methods. 

 The book is fully illustrated and fairly well bound and printed. The 

 book is concise, practical and thoroughly up to the times and we 

 heartily commend it to the student and busy practitioner. The 

 publishers have generously undertaken to furnish all the reagents and 

 apparatus which the work calls for, a great convenience to those liv- 

 ing away from centers of chemical supplies. 



Ihtroduction to the Study op Lichens, with a supplement and ten plates. 

 By Henry Willey, New Bedford, Mass. pp. 272. Published by the 

 author, price $1.00. 



In publishing this Introduction Mr. Willey has rendered a ser- 

 vice alike to beginners and advanced lichenists. The object of the 

 work, as the author says, " is to prepare the way in some measure for 

 the study of the great v^iters on the subject," and in this he has suc- 

 ceeded most admirably. The plates, ten in number, in black and 

 white are placed at the end of the book, and serve their purpose in 

 illustrating the text. We trust that this excellent introduction may 

 lead to renewed interest in this greatly-neglected branch of botany, 



A Primer op Botany, by Mrs. A. A. Knight, pp. 115. Boston: Ginn & Co., 

 1887. 



Little Flower People, by Gertrude Elizabeth Hale, pp. 85. Boston: Ginn 

 & Co., 1887. 



These two little books are sure to find a welcome in the school 

 room and in the home, and not only will they recommend themselves 

 to the teacher, but, if properly used, will be readily accepted by the 

 youngest pupils. Mrs. Knight teaches her lesson by a series of 

 short and comprehensive questions, leading the pupils to examine 

 and think for themselves, and supplying whatever information and 

 practical demonstration may be necessary to fix the ideas in the 

 youthful mind. Miss Hale, on the other hand, appeals to the imagi- 

 nation, and in clothing the flowers in the garb of fairy-folk, teaches 

 an equally acceptable lesson, which will prove attractive either to old 

 or young. Both books are well illustrated. We commend them to 

 all who have young children in their charge.
