— The University of Pennsylvania is about to begin the issue 

 of a series of monographs representing work done in the fields 

 of philosophy, psychology, and ethics. The first number 

 is announced for April, and is a work on "Sameness and 

 Identity," by Professor FuUerton. Following this num- 

 ber will be a series of studies from the laboratory of ex- 

 perimental psychology, and an edition of Descartes' "Medi- 

 tations," with Latin and English texts, and philosophical 

 commentary. The series will be published by the University of 

 Pennsylvania Press, under the editorship of Professors Fuller- 

 ton and Cattell. Dr. E. J. James, professor in the "Wharton 



School of Finance and Economy, is preparing for the American 

 Economic Association a paper on the "Canal Question in the 

 United States." He will show how great a mistake the Amer- 

 ican people have committed in allowing its canal system to 

 fall into decay. He is warmly in favor of the construction of 

 a new system which shall urite the great water-ways of the 

 West to the Atlantic seaboard at various points. Dr. Simon N. 

 Patten, professor in the Wharton School of Finance and Econ- 

 omy, has in press a book entitled "The Economic Basis of 

 Protection." He "re-examines the whole question of free 

 trade versus protection in the light of modern economic the- 

 ories, and shows how the free-trade theories are inconsistent 

 with the best results of late economic thought."

DICTIONARY 



OF 



ECONOMIC PLANTS, 



BY JOHN SMITH, 



Associate of the Linnman Society, author of 

 " Historia Filicum, " " History of 

 Bible Plants," etc., etc 

 For more than forty years Mr. Smith was 

 connected with the Royal Gardens, Ken., 

 which gave him remarkable opportunities for 

 becoming acquainted with the largest collec- 

 tion of living plants, native and exotic, ever 

 brought together; and from 1846, he was 

 associated with the late Sir. W. Hooper in 

 building up the Kensington Museimi of Eco- 

 nomic Botany. Based on all this experience, 

 Mr. Smith has produced this Dictionarj' which 

 gives under their popular names information 

 about plants that furnish the wants of man, 

 their history, products and uses. Having 

 received a large invoice of this book from 

 the London publisher, we offer to mail copies 

 postpaid at a discount. 



List price, $3.50 : our price, $2.80.

A New Method of Treating Disease. 



HOSPITAL REMEDIES. 



What are they ? There is a new departure in 

 the treatment of disease. It consists in the 

 collection of the specifics used by noted special- 

 ists ofEurope and America, and bringing them 

 within the reach of all. For instance, the treat-i 

 ment pursued by special physicians who treat 

 indigestion, stomach and liver troubles only, 

 was obtained and prepared. The treatment of 

 other physicians celebrated for curing catarrh 

 was procured, and so on till these incomparable 

 cures now include disease of the lungs, kidneys, 

 female weakness, rheumatism and nervous de-, 

 bility. 



This new method of " one remedy for one 

 disease " must appeal to the common sense of 

 all sufferers, many of whom have experienced 

 the ill effects, and thoroughly realize the ab- 

 surdity of the claims of Patent Medicines which 

 are guaranteed to cure every ill out of a single 

 bottle, and the use of which, as statistics prove, 

 Aas I uined more stomachs than alcohol. A cir., 

 cular describing these new remedies is sent free 

 on receipt of stamp to pay postage by Hospital 

 Remedy Company, Toronto, Canada, sole pro- 

 prietors.
