U. S. Commission of Fish and Fisheries, 
Washington , March 6, 1896. 
The Bulletin of the United States Fish Commission for 1895 was completed during 
the early part of the year 1896, and subsequent to the death of Commissioner Marshall 
McDonald, which occurred in Washington on September 1, 1895. As the investigations 
covered by the papers appearing in this volume were mostly made under the adminis- 
tration of Mr. McDonald, and during his occupancy of the Commissionership, it is 
deemed right that he should be credited with the same by the retention of his name 
on the title page of the volume, although none of the papers included was issued prior 
to his death. 
Herbert A. Gill, 
A cti ng Commissioner.
