Thi-: research vessel of the Association for the 

 Advancement of Scientific In^•estigation in the 

 Adriatic, was built on the D'Este shipvards hv the 

 Stabilimento Tecnico of Trieste. Though being of 

 rather modest dimensions, she is most sea-worthv 

 and. on account of her excellent appointments, 

 can he considered a model of her kind. The 



for covering the rooms located in the hull are only 

 •70 metres in height, which greatly reduces the 

 side-pressure of the wind. Ample space is provided 

 on the plane deck plates, for installing all kinds of 

 apparatus and doing scientific work. These 

 structures are fitted sideways with c]uadrangular 

 skylights and protectiw gratings as well as with

Adna, 



" Adria "' is mainh- intended for the oceanographical 

 and biological in\estigation of the .\driatic. working 

 in conjunction with the Austrian Zoological Station 

 at Trieste. 



The chief measurements of the ship are as follows : 

 Length over all ... ... 20-5 metres. 



Maximum width ... ... 4 



Height -'-4 „ 



Draught ... ... ... 1-5 ,, 



Capacity ... ... ... 45 tons. 



The hull is made of wood, the frame and kuel 

 being of oak. and the inside and outside planking of 

 pitch-pine. A skin of copper plate protects the hull 

 below water against the attack of ship worms. 



The various teak wood structures erected on deck 



hinged hatch lids. The deck is encircled by an iron 

 railing, the lower apertures of which are closed b_\- 

 netting : the upper bars are fitted w ith pulle}s for 

 lowering oceanographic instruments. The front part 

 ot the bow (as far as the mast) is set apart for 

 fishing operations and. therefore, is equipped with the 

 most warious outfits, comprising a winch for the 

 rapid hoisting of instruments and nets able to raise 

 a weight of several hundredweight from the bottom 

 to the surface of the sea. While being generally- 

 operated bv electricitx', this winch can as well be 

 worked hv hand. On its axle are mounted four 

 drums actuated separately and which are designed 

 for plain ropes, cables, piano wires and anchor 

 chains respecti\'el\'. The rope carrying a net or
