SCIENCE.

Mary A. Spear, late principal of the Model School of West Chester 

 (Pa.) State Normal School. These plant studies combine drill in 

 reading with sound botanical information, calculated to serve as 

 a useful basis to later study. At the same time care is taken that 

 the information shall be obtained by actual observation of leaves, 

 stems, and flowers. A feature of this book is its arrangement, 

 which enables it to be taken up in the autumn, if the study cannot 

 be begun in the spring. 



— Neptunia, January, 1892, contains a map showing the dis- 

 tribution of Plankton, in the North Atlantic, as far as it was 

 ascertained by the expedition of the Humboldt Stiftung. In an 

 accompanying paper, Herr F. Sohtitt discusses the result of the ex- 

 pedition. 



— We learn from the Scottish Geographical Magazine that two 

 handbooks of professional instructions for the trigonometrical and 

 topographical branches of the Indian Survey Department have 

 just been issued from the office of the former at Dehra Dun, in 

 the North-West Provinces. They have been prepared by Colonel 



G. Stahan, R.E., under the direction of Colonel H. R. Thuillier, 

 R.E., the Surveyor-General, and will prove most useful to the 

 numerous officers of that department, as well as to students 

 and others in this country who contemplate joining the service. 

 Some of the miscellaneous chapters, such as those on the care and 

 treatment of elephants and on the health and management of a 

 party, will be found to have a good deal of interest for the gen- 

 eral reader, while the more purely technical parts contain full 

 and instructive information as to the important and miscellaneous 

 scientific tasks which fall to the lot of the Indian surveyor. 



— Bret Harte's young daughter. Miss Jessamy Harte, will make 

 her literary debut in the July Ladies' Home Journal with a most 

 entertaining description of "Camp Life in the Adirondacks," in 

 which it is claimed every evidence shows itself of inherited literary 

 tendencies not unlike those evidenced in Bret Harte's earlier work. 

 Miss Harte is a girl still in her teens and has artistic as well as 

 literary proclivities, as one of the illustrations accompanying her 

 first article shows. 



Exhaustion 



A wonderful remedy, of the 

 highest value in mental and 

 nervous exhaustion. 



Overworked men and women, 

 the nervous, weak and debilitat- 

 ed, will find in the Acid Phos- 

 phate a most agreeable, grate- 

 ful and harmless stimulant, giv- 

 ing renewed strength and vigor 

 to the entire system. 



Dr. Edwin F. Vose, Portland, Me., says: 

 ' 'I have used it in my own case when suffer- 

 ing from nervous exhaustion, with gratifying 

 results. I have prescribed it for many of 

 the various forms of nervous debility, and it 

 has never failed to do good."
