14.—DIGEST OF THE APPENDICES WHICH ACCOMPANY THIS REPORT. 
The appendices which accompany this report consist of thirty-two 
papers, all of which have a more or less direct bearing upon the work 
of the Fish Commission. <A large proportion, moreover, relate to the 
work accomplished at the stations of the Commission and by the vessels 
in its service during the current year. Several of the longer papers 
will be published in pamphlet form for separate distribution. The ar- 
rangement of the appendices is as follows: 
A.—THE FISHERIES, 
This appendix consists of a comprehensive report by the Commis- 
‘sioner, Prof. Spencer F. Baird, upon the Sea Fisheries of Lastern North 
America. ‘Fhe paper was mostly prepared in 1877 and 1878, but was 
withheld from year to year for revision and completion, until it became 
evident that the author’s declining health would prevent his giving the 
subject further attention. It is an important contribution to the liter- 
.ature of the American fisheries, and shows much careful research and 
thoughtful study. 
B.—ScIENTIFIC INVESTIGATION. 
Four papers are included in this appendix, two relating to fishes and 
two to marine invertebrates. ‘Lhe first is by Prof. D.S. Jordan and Mr, 
D. K. Goss, his assistant, upon the flounders and soles of America and 
Europe; the second is by Professor Jordan and Mr. C. H. Eigenmann, 
upon the Scienide (drum-fishes, etc.), of the sameregion. The former 
‘is illustrated by 23 figures the latter by 12 figures. Prof. Edwin Linton 
reports upon the Entozoa, or intestinal worms of the marine fishes of 
New England, and Mr. J. Walter Fewkes, upon the medusz collected 
‘by the steamer Albatross during its cruise to the Gulf Stream in the 
winter of 1885-86.
