SECOND DAY. 



j The President, Dewey, took the chair, and among the distin- 

 guished savans present (new arrivals) were President Day, Prof. 

 Hitchcock, Prof. Bailey, of West Point, Prof. Coffin, of Nor- 

 iwalk, Ct., Dr. S. Bacon of Boston, Dr. Jackson of Boston. 

 I Prof. Rogers, from the committee on business, said they had 

 prepared a programme ; the report was rc;id of the committee ap- 

 pointed last year, on addressing a memorial to the Secretary of the 

 Navy on the subject of the Gulf Stream. Lieut. Maury is chair- 

 man of the committee ; the report is but provisional, and the com- 

 mittee desire to be sanctioned in a continuance of functions. It 

 :ontained a copy of instructions to officersof the navy for making 

 i)bservations on the Gulf Stream, and a letter of the Secretary of 

 the Navy, who wishes these instructions to be given to the officers 

 )f the Columbus now going out, in order to further the views of 

 he Association in a thoroughly analytical examination of the Gulf 

 5tream. The nature of the instructions may be gleaned from the 

 bllowing subjects to be inquired into : 



i Course and set of the stream. 



Temperature of the water at different depths. 



Depth of current and velocity at different depths. 



Fluctuations of the current in gales of wind. 



Character of the bottom in various places. 



The diderence between the eds;es and centre of the stream. 

 I The limit, force and set of dili'erent currents. 



I The line of deep-sea soundings to be noted between the coast and Gulf Stream 

 |11 along the coast ; which would be of great value to vessels approaching the 

 oast in bad weather. 



', The nature, extent and course of the Gulf Weed. 



' The places, appearances, &c., of any drift wood; some of ^\hich drifts from 

 le Mississippi and is lodged on the Tortugas. 

 I Icebergs and the currents around them. 

 I The strength and durability of storms. 



Meridian altitudes of the stars. 

 ; Sights on the instruments to take P. M. as well as A. M. observations. 



Streaks of warm and cold water ; their limits and breadth. 



Formation of shoals and spits of land. 

 I Fishes of various Islands, and what are preferred for food. 



Volcanic regions, their altitude, appearance, &c. &.c. 



Geological structure of all islands. 



Rise and fall of tides at all places. 



Corals, mollusca, fishes, &c., at all places. 



And for all this an abstract log is to be kept. 



. The committee also say that the prismatic azimuth compass is 



|) be employed mounted on its tripod and placed abaft the binna- 



le, and to be placed as free from the influence of the guns and 



|l other ferruginous matter as possible ; and the difference between 



and the ordinary compass, to be also carefully noted. The entire 



Dsence of coralinc in the Gulf, which is always found in simi- 



r latitudes in Asia, &c. is to be carefully noted ; as this is 



ipposed to indicate counter currents of hot and cold water, at 



fferent depths and on different sides ; for this it is proposed to
