length of fifteen feet ; but the difficulty in this comparison 

 would be that the undulations of this latter fish would be 

 from side to side, and not in a vertical direction. The con- 

 ger, too, when swimming, would move its body in horizontal 

 curves. Flat fish, however, have a motion in the vertical plane, 

 and it is therefore suggested that this may be a ground fish 

 of some sort which occasionally comes to the surface. 2 A,

AQUARIUM AT MANCHESTER. 



The interest excited by the successful opening to exhibi- 

 tion of the great aquarium at Brighton, England, has led to 

 the adoption of measures for a corresponding establishment, 

 although possibly on a smaller scale, at Manchester. The 

 permanent building will be completed and opened some time 

 during next year, and arrangements have already been made 

 for securing and preserving, at once, such marine animals and 

 plants as can only be obtained during the summer season. 



PROGRESS OF THE NAPLES AQUARIUM. 



According to the report of the committee upon the estab- 

 lishment of zoological stations in different parts of the world, 

 as presented at the meeting of the British Association, the 

 zoological station at Naples, under Dr. Dohrn, will be com- 

 pleted and in working order by the beginning of January, 

 1873. Of this undertaking we have already spoken in our col- 

 umns, and trust that it will meet the expectations of its dis- 

 interested founder. It has already become an institution of 

 international importance, and is receiving gifts of books and 

 money from various sources, although the great body of the 

 expense is supplied by the private means of Dr. Dohrn, who 

 has already laid out nearly $40,000. The object, as hereto- 

 fore stated, is to furnish to naturalists conveniences for inves- 

 tigating the marine animals of the Gulf of Naples, by supply- 

 ing comfortable working rooms, fitted up with instruments, 

 books of research, and aquaria with an ample supply of sea- 

 water, together with all the necessary boats, dredges, and the 

 like. It is announced that some steam-ship companies are 

 prepared to grant free passage to the naturalists of this estab- 

 lishment, with their goods and collections. 



With the station is connected a magnificent aquarium for
