 upon the methods of preparing various marine foods. 

 Owing to serious delay on the part of the manufacturers, 

 this apparatus was unfortunately not installed until late 

 in the season. 



4. Running fresh water was introduced into each of 

 the large investigation rooms upon the second and third 

 floors of the building, and enameled iron sinks were like-

5. A contrivance was designed and constructed for the 

 purpose of de-aerating the salt-water supply of the labora-

 1. Biological Survey.— Much progress was effected 

 during the summer, as well as during the preceding 

 winter, in the preparation of the report upon the bio-

 necessary to extend this work through the present winter; 

 and the director is again in residence at Woods Hole, 

 engaged in the completion of this project. At the present 

 time it may be stated that the plotting of the distribution 

 charts, several hundred in number, has been nearly com-

 annotated list of the local fauna and flora (based both 

 upon original observations and published records) is not
