350 DRAWING WITH HOUSE CURRENT AVOIDANCE OF HEAT [CH. X § 504. When the small currents from the house circuit are used the heat is not great enough to injure most specimens mounted in balsam. For live objects and objects mounted in glycerin or glycerin jelly, etc., it would be wise to place a water-cell in the beam before it reaches the microscope (see § 364, 394a, fig. 206). FIG. 196. DRAWING OUTFIT FOR THE HOUSE LIGHTING SYSTEM WITH A BLACK CLOTH TENT OVER THE MICROSCOPE. This arrangement answers well for a moderately lighted room. Naturally the opening for drawing should face toward some dark furniture or the dark side of the room, not toward a window. 5 Separable cap to attach to the separable plug in a socket of the house lighting system. w r One of the supply wires cut and inserted into the binding posts of the rheostat (see fig. 188). / Small arc lamp for supplying the illumination. It is at the level of the mirror and at right angles to the microscope. m Mirror of the microscope. t Cloth tent over the microscope. It appears semi-transparent as it was left in position during but part of the time when the photograph was taken.
