_erer of Bering Strait. By Peter Lauridsen (ete.). Revised by

This edition is a good deai condensed, especially in the matter of 
references, and does not have all the illustrations of the original. There 
are also a good many slips or typographical errors, which affect its 
value as a work of reference. Some of those important in connection — 
_ with the present paper are as follows: page 31, line 4, ‘‘ 60° 50’ N.” 
latitude should be ‘‘ 62° 50’.” On the last line of the same page ‘‘longi- 
tude” should be ‘‘latitude.” Page 32, after ‘‘ cloudy weather” in the 
second line from the bottom, the whole remaining record of August 
15th is omitted altogether. The sentence beginning ‘‘From noon” 
relates to August 16th, nautical reckoning. Page 38, line 5, ‘‘30° 19’ 
east” should be ‘30° 17’ east ;” line 20 after ‘“‘half west” should be 
inserted ‘*south by east, by compass.” Page 51, line 4 from bottom, 
‘‘latitude” should be ‘‘ longitude.”

I may add that a number of references to Russian articles 
treating of Bering will be found in my Bibliography of charts 
and publications relating to Alaska and adjacent region, published 
by the U. 8S. Coast Survey in 1879.
