EDITORIAL COMMENT. 
Death of Dr. Lütken. — Copenhagen advices notice the death 
of Dr. Christian Frederik Lütken, the honored Emeritus Professor 
of Zoólogy in the University at Copenhagen and one of the most 
eminent of modern zoólogists. Dr, Lütken was born in 1828, and 
was seventy-three years of age at the time of his death. He is the 
author of many scientific papers, the most important being on fishes, 
and his best work being on the fishes of the open sea and the changes 
passed through in their development. The most extensive of these 
is a series called *Spolia Atlantica," discussing the rich material 
brought in by Danish seamen. Other notable papers are on the 
lantern fishes, the flying fishes, the remoras, the sculpins, the fishes 
of Greenland, and the fresh-water fishes of Brazil. 
In all his work Dr. Lütken was extremely conservative, never 
jumping at a conclusion, and content to leave a question unsettled 
in default of adequate material to form an opinion. Thus few scien- 
tific men have had fewer errors to correct than he. 
-= Dr. Lütken at fifty-five is remembered as a large man with a fine 
face, hale and hearty, and one of the most genial and helpful of 
all European ichthyologists. 
School Science is the title of a new journal devoted to the interests 
of science teaching in secondary schools. Itis published in Chicago, 
and edited by C. E. Linebarger, with the assistance of a number of 
science teachers scattered over the country ; and is intended by the - 
editors to be conducted by and for the science teacher. 
Within the last few years, largely because of the employment of col- 
lege-trained teachers in the secondary schools, the quality of the work 
done in these schools has been vastly improved, especially in the line 
of science, and for its grade no better work is done in science to-day 
than that done in a few American high schools. To enlarge the 
field of the teachers to whom this success is due, and to widen their 
influence, is the mission of the new journal, which merits the support 
of all who see the desirability of having science scientifically taught.
