will probably reach St. Johns about the 26th of this month, and by 
the 4th of July, it is thought, the Falcon will sail for the far North. 
It is hoped that Peary's headquarters in Bowdoin Bay will be 
reached by July 25. If assured of the safety of Peary's party, some 
of the members of the expedition will then pay a brief visit to Elles- 
mere Land in their search for the missing naturalists, Bjorling and 
Kallstenius, who were ship-wrecked on the Carey Island two years 
0. 
The auxiliary expedition and the Peary party, it is expected, will 
leave Bowdoin Bay, September 1, and sail on the Falcon for this city, 
arriving here probably by the 15th of that month. 
The Retirement of Professor Dana.— The resignation of Pro- 
fessor Dana from the position he has long held in Yale University is 
announced. 
Professor Dana is eighty-one years of age, and is compelled to aban- 
don further active work by feeble health. His resignation has just 
been accepted. He graduated from Yale in the class of 1833, returned 
to college as tutor and succeeded to a full professorship fifty years ago. 
Since then he has had charge of the department of natural science. 
Born in Utiea, N. Y., February 12, 1823, Dr. Dana early became 
interested in the researches of Professor Benjamin Silliman, and 
through them was attracted to New Haven. Under his guidance he 
was graduated from Yalein 1833 and immediately appointed instructor 
of mathematies to midshipmen in the United States Navy, and in this 
capaeity visited the seaports of France, Italy, Greece and Turkey 
while on board the warships Delaware and United States. In 1836-38 
he was assistant to Professor Silliman in the department of chemistry 
at Yale, and while thus engaged was appointed mineralogist and geol- 
gist to the exploring expedition to the Southern and Pacific Oceans 
under Captain Charles Wilkes. He was on the corvette Peacock, 
wrecked at the mouth of the Columbia River. He returned in 1842 
and spent some years on his portion of the report, which was partly 
prepared in Washington. In 1844 Dr. Dana married Professor Silli- 
man's daughter, Henrietta Frances, and he has since continued to 
reside at New Haven. In 1850 Dr. Dana was appointed Silliman- 
Professor of natural history and geology at Yale, and the same year 
became associate editor of the American Journal Science and Arts, 
founded by the elder Silliman in 1819., Later he became editor-in- 
chief, with his son, Edward S. Dana, as assistant. In 1872 the Geo- 
logical Society of London conferred on Dr. Dana its Wollaston med-
