254 THE MICROSCOPE. — 
THE ENGLISH SPARROW IN NORTH AMERICA; ESPECIALLY IN ITS RELATION TO 
AGRICULTURE. Prepared under the direction of Dr. C. Hart Merriam, Orni- 
thologist, by Walter B. Barrows, Assistant Ornithologist. 
This rather bulky pamphlet of 405 pages forms bulletin No. 1 
of the division of Economic Ornithology and Mammalogy, U. 8S. De- 
partment of Agriculture. It is a history of the importation of the 
sparrow, together with a record of its habits, increase, checks, ete. 
The English-sparrow question, as Dr. Merriam says, has grown to 
be a serious problem in economic science, and the government has 
done well in thus collecting the evidence against this pest, with 
suggestions for its extermination.

THE TREATMENT OF THE MoRPHIA DiszaseE. By Dr. Albrecht Erlenmeyer. 
Physicians’ Leisure Library, Detroit; Geo, S, Davis, publisher. Pp. 113; 
price, 25 and 50 cents. 
This little book is a chapter taken from the well-known work of 
Erlenmeyer on the morphine habit, and contains an epitome of the 
three methods of treatment in vogue—the gradual, the sudden and 
the rapid modes. The author’s own preference is for the last-named 
method, but we hardly think that the majority of those who have 
had experience in the treatment of this habit will agree with him on 
this point. It is rarely the case that a patient is so low physically 
that the sudden method, the immediate withdrawal of the drug, will 
not prove the most successful plan to pursue. The first twenty-four 
hours will usually break the back of the habit, and although the 
delirium maniacale may be severe, the habit is pretty effectually
