412 NATURAL SCIENCE. Dec, 



In the south-west part of the lower storey is a general working 

 room (GR), 7'34m, by 4-401. with three windows and with exits to 

 the washing-room and the south entrance-hall (5 F). It has three 

 work-tables (bb), and in the middle a large aquarium-table (ab). 

 This room is set apart for younger students, who stay at the place 

 in order to get a general idea of the flora and fauna of the sea. 



From the south entrance-hall, which is more spacious than the 

 other, and which has doors into the general room and the washing-room, 

 a stair leads to the upper storey, which contains the laboratories 

 proper. A long corridor (A') divides this storey into two halves, and 

 from it doors open into the seven studies {I. -VII.), which face north 

 and east, into a smaller store-room (F) for glass and reagents, and 

 into a large common room (G S), lit by three windows facing south, 

 and opening into a small corner room (B), also facing south, which is 

 intended to contain the library of the station at some future day. In 

 the common room is a work-table, reserved for emergencies, a 

 warming oven, microtomes, a named collection of animals from the 

 neighbouring sea, and so on. This room is principally to be regarded 

 as a common study for those who wish to use the collection for 

 comparison, to use the warming oven for imbedding in paraffin 

 and such like work, and to use the microtomes. Each private study 

 has on an average an area of twelve square metres and a height of a 

 little over three metres. Each contains a large, excellent work-table (b) 

 with solid oak top, a treadle arrangement for the lens-stand after 

 Sven Loven's model, and a set of drawers. Each is provided with a 

 dissecting microscope, a bookshelf, a copper-covered aquarium-table ((/) 

 with waste pipe, a sink (s), water supply to the aquarium-table and 

 sink, a set of glass vessels and aquaria of different sizes, a lift (h) 

 from the washing-room, and all necessary reagents, which are sup- 

 plied on demand. Microtomes, balances, warming ovens, a Hartnack 

 microscope of high magnifying power, and similar apparatus, are kept 

 for the common use and are lent out as required. 



From the upper storey a staircase ascends to a light and spacious 

 attic. 



Altogether the laboratory furnishes working room for ten persons 

 at once, the common room not being included, since it ought to be 

 accessible to all, and its only work-table is kept in reserve in case 

 some eminent naturalist should turn up unexpectedly. 



The whole building is traversed by pipes, which supply the 

 aquaria and the studies with fresh sea-water ; the supply to the upper 

 storey and to the large cement aquaria consists of iron pipes 

 enamelled on the inside. The supply of the lower storey, which was 

 installed in 1894, consists of very wide, thick-walled glass tubes sur- 

 rounded by a somewhat larger cover of brass, while the space between 

 the two is filled with a mixture of wax and Venetian turpentine All 

 the T-pipes and angle-pipes of this new supply are constructed of 

 well-tinned brass, and the cocks are of ebonite.
