Translocation of Latex and the Multiple Razor. 195 
cutting a leaf or stem simultaneously into a given number of parts. 
The instrument described below has been successful in some 
preliminary experiments. 
This “ Multiple Razor” is composed essentially of a number of 
wooden blocks threaded on two bolts, some of the blocks having 
just the two holes necessary for the bolts and others being sawn 
half-way down and fitted with small screws which, when tightened, 
grip a safety razor blade inserted in the cut. The razor blocks are 
fitted with the blades and the ‘ blind ’ blocks may he inserted between 
them on the bolts. When the razor blocks alone are used there is 
half an inch between the blades, and this can be increased by half¬ 
inches up to any required distance. The holes for the bolts should 
be bored a little larger than the diameter of the bolts so that each 
block moves a little. When all the required blocks have been 
threaded in their proper positions on the bolts they are tightened 
up with butterfly screws and a final adjustment of each razor block 
must be made to bring all the razor edges level with each other. 
Then by means of the butterfly screws they can be screwed tightly 
so that no movement of the individual blocks is possible. 
It has been found convenient to use the single-edged blades 
supplied with the Christy Safety Razor. Plane or lime wood forms 
satisfactory material for the wooden blocks. The instrument could 
be varied to suit any particular requirements, but the following 
details may be of use as showing a medium size ‘multiple razor’ 
for general use. The letters refer to Figs. 1—3.
