There is about fifty feet of Fitter's benching, provided with 

 tool drawers, etc., and plenty of shelving. There is also a 

 gas oven, a very large and deep sink, and racks for holding 

 materials. The space beneath the raised seating in the Lecture 

 room is utilised for keeping timber in, and is therefore provided 

 with a door in the east wall and a port hole in the northern wall. 

 The arrangements adopted in the workshop for bringing machines 

 in and out of gear have been carefully planned and erected, and 

 consist partially of friction clutches and partly of fast and loose 

 pulleys. The details however having a merely mechanical interest 

 will not be pursued further. The walls of all the rooms are 

 kalsomined a faint green ; and painted dark green up to about 

 the height of four feet above the skirting boards which are dark 

 red. The top of the painting is picked out by a square border in 

 red. The wood work being mostly of cedar and colonial pine is 

 not painted but varnished ; the elfect on the whole is very 

 satisfactory. 



November 2nd. — A good deal of work has been done in the 

 Laboratory during the six months we have been in possession, 

 the electric light is still unfinished, but the electric supply and 

 the moveable storage cells have done good service. One drawback 

 of the enormous ventilation which the Sydney summer demands 

 is that the building is apt to be cold in winter. The small Peat's 

 valves are not quite satisfactory, and the engine exercises a variable 

 magnetic influence in the room next to it. By an oversight the 

 doors in the non-magnetic part of the building have been supplied 

 with ordinary iron locks and these have given some trouble. They 

 will however be replaced shortly by brass locks. We have had to 

 contend with several severe dust storms, to which, from its situa- 

 tion the building is much exposed — the result has been that a 

 good deal of cleanine: has had to be "one throuijh.
