DESCRIPTION OF TEST. 
(i) Five pieces of wire, 20 mm. long and 1 mm. 
thick have to be bent into certain shapes, then 
hammered straight again. 
(i) Long box in which 15 blocks of wood are 
placed side by side like drawers in a chest of 
drawers. Blocks vary in weight between 20 and 
60 gm. Handles are attached by which blocks 
can be raised but not pulled right out. Adjacent 
blocks are raised, two by two, one in each hand, 
and the candidate has to say in each case whether 
the right or left hand block is the heavier. 
Board with 60 holes, 20 measuring 5 mm., 20 
3 mm. and 20 2 mm. across. Mounted needle 
1 mm. in diameter has to be placed in all holes in 
turn without touching sides, first in the candidate’s 
own time, and then in time with a metronome 
set at 60. Contact with sides automatically 
recorded. 
Candidate has to file with right hand, keeping 
pressure steady, and file in one vertical plane, 
while with the left hand he moves a shutter up 
and down as quickly as possible. Number of 
movements of shutter automatically recorded, 
while electric contacts register if the pressure 
falls below or rises above a certain range, or if the 
file leaves the correct vertical plane. 
A metal sheet with about 20 irregularly shaped 
openings is held in the smoke of a lamp. The 
surface is rubbed clean, and the candidate cleans 
inside the openings. 
Candidate holds an old photographic plate be- 
tween his hands for two minutes, and the amount 
of staining is investigated.
