178 PROCEEDINGS OF SECTION B. 



they have been retained, but to prevent splashing as much as 

 possible, a small inverted flower-pot, without a bottom, is placed 

 in the sink, and an inward projecting rim of sheet indiarubber is 

 placed round the basin's edge ; this also tends to prevent breakage 

 against the earthenware basin. 



The lower end of the inverted flower-pot, i.e., the real top, is 

 closed by a perforated wooden or lead disc, so that the flower-pot 

 can be used as a receptacle for matches, filter paper, &c. The 

 ordinary earthenware rubbish receptacle is too large, takes up too 

 much space, and is the cause of much broken apparatus in 

 washing up. 



The space in front of the basin is utilized as a cupboard for the 

 two students in common. 



Each student's table-top space is five feet by two feet three 

 inches in the main laboratory, and if the laboratory is not full he 

 can have a space ten feet long. For every four students there is 

 a double draught cupboard on the working benches, two feet nine 

 inches square, divided down the centre (Plates XV. and XVI.), 

 afibrding sufiicJent space for all the ordinary operations of boiling, 

 evaporation, &c., so that he has no need to leave his bench for 

 such purposes. These draught cupboards are glazed at top and 

 sides, and have draught flues leading downwards. But it will 

 probably be found more convenient to use the upcast flue as in 

 Plate VII. 



The plan shows down draught tubes from the bench draught 

 closets, as well as the upcast ones, so that the alternative arrange- 

 ments may be fully considered before the final selection is made, 

 and the fittings proceeded with. 



Where these draught cupboards have moveable sashes, the 

 weights are attached by copper-covered steel tapes, passing over 

 pulleys down into tubes in the central longitudinal space, between 

 the two halves of the cupboards left for the draught flue, gas and 

 and water pipes, thus avoiding the necessity of reducing the 

 openings of the cupboards by having weight boxes in the front. 

 The front framing can thus be made solid and correspondingly 

 narrower. 



Attached to each bench is a small leather-covered iron seat, or 

 rest, like a bicycle seat. This is supported on a strong iron 

 bracket, moveable so that it can be turned on one side out of the 

 way. The drawers are reduced to two, with suitable subdivisions, 

 for it is found that tlie average student does not want more, and 

 if he has more drawer space he does not properly use it, his 

 apparatus is too scattered, and he wastes much time searching 

 through all the drawers for some small article. The drawers are 

 subdivided for corks, tubes, &c., and there is one provided with a 

 moveable tray for blowpipes, files, and similar small articles, 

 which can, if necessary, be taken out and placed on the bench. 

 By this means the two drawers afford nearly as much real 

 accommodation as the half-dozen usually provided.
