No. XIV. Hints for Teachers of Physiology. 



By H. P. BOWDITCH, M. D., Professor of Physiology, Harvard Medical School. 

 Paper o 58 pages. Price 20 cents. 



IN this little book an attempt has been made to show how a teacher 

 may supplement his text-book instruction by means of simple ob- 

 servations, and experiments on living bodies or on organic material, 

 thus imparting to his pupils a knowledge of the foundation on which 

 Physiology rests, and at the same time bringing the impressions made 

 on the senses to aid the memory in retaining the facts communicated 

 in a purely didactic way. 



No. XV. Observation Lessons on Common Min- 

 erals. BY HENRY LINCOLN CLAPP, Master of the George Putnam School, 

 Boston. Paper. 80 pages. Price, 30 cents. 



THIS little book is not an epitome of any work on mineralogy, nor 

 simply a collection of suggestions, but a specific, practical guide 

 for the use of the ordinary teacher. It contains many transcripts of 

 the pupils' records of their own personal observations, showing what 

 can be done by ordinary pupils under ordinary circumstances. The 

 lessons will lead the pupils to see the truth, state it, and at the same 

 time to become practically acquainted with common minerals, and to 

 make collections of their own. The errors in language, too, can be 

 detected and remedied by carrying out the design of these lessons. 

 They can be given in forty weeks, by devoting one hour each week to 

 the work. 



A list of simple apparatus needed, names of reference books, infor- 

 mation on additional minerals, and a chapter on methods of forming a 

 mineralogical cabinet, are added. 



Pupils* Note Book to accompany No. XV., 10 cents. 



Specimens to Illustrate, from 50 cents to $10.00. 



Asa Gray, Incite Prof, of Natural 

 History, Hamard Univ.: Those who 

 have not had the advantage of the course 

 of lectures should study these primers 

 thoroughly, and follow the directions they 

 give. 



Dr. Wm. T. Harris : I commend 

 the series for the kind of work which 1 

 think ought to be done in the lower 

 grades. 



Albert H, Tuttle, Prof, of Zoology^ 

 Ohio State Univ., Columbus: I have a 

 high esteem for the whole series.
