ACKLAND’S MICROSCOPIC LAMP. 
Tuts Lamp is offered to Microscopists as thoroughly 
all the latest improvements, and is furnished with 
HaIce's Porcelain Shade, which, whilst shielding the 
observer’s eyes from the glare of the Lamp, aéts asa 
reflector to increase the brilliancy of the illumina- 
tion. The giass reservoir is shallow, so that the 
paraffin rises freely and feeds the wick regularly. The 
reservoir rotates in the arm, B, so that the flat or edge 
side of the flame can be used. The shade can be 
adjusted to a proper position, as regards the flame, by 
sliding up or down the arm D, and the lamp fixed at 
any required height by the clamping screw,c. Asthe 
tube E carries the tube D, when the Lamp and shade 
are properly adjusted, the whole may be raised or 
depressed without deranging that adjustment by 
_ Sliding up or down the arin B. The brass wick-mount 
is hinged, so that the gallery or chimney can be 
turned back to faciiitate turning and lighting.
