Court without hesitation.
This
point is noteworthy, because evidence
of this nature has always been given in the past by an expert in his own
particular professional field, such as a fingerprint expert, gun expert,
pathologist, etc. Such a situation, however, did not arise in this
instance because this appears to be the first occasion upon which a
crepe-rubber-soled footwear impression has been positively identified
and accepted in a court of law.
Both the prisoners pleaded guilty at their trial, when Mwas given
eighteen months imprisonment, and W, who had previously borne a
good character, was Bound Over in the sum of £5 for two years.

IT will be agreed
that
the main classes of photographic work done at
Police Headquarters are fingerprint photography; the copying of
photographs, documents, plans, etc. ; the production of enlargements
of fingerprints and of small objects such as bullets, bases of cartridges,
fragments of glass, etc. ; the photographing of prisoners, and occasion-

camera should be large enough to take a
12
X
10
inch nega-

matched right angle prism, and the other a 6- or 7-inch lens; have a
bellows extension of about 4feet; must have racking movement
so
that
the camera can be moved laterally on its stand for at least
12
inches, or be so fitted that it can be turned at right angles to its
stand and locked in
that
position.
The
stand to which the camera is
attached must be fitted with a smoothly controlled rack and pinion
movement to allow the camera to be raised or lowered at least 2feet;
the camera and stand
must
move backwards and forwards smoothly,
but
must also have some arrangement whereby they are held rigid
at any desired distance from the object being photographed.
A camera embodying all these essentials has been in use at the
headquarters of the Aberdeen City Police for the past twelve months,
during which time it has been well tested on all classes of work and
found to be satisfactory. As new apparatus is meantime both difficult
to obtain and very highly priced, all the parts required were purchased
