MANUFACTURE OF PHOTOGRAPHIC SENSITIVE PLATES.

Quite recently Messrs. Marion & Company, London, began on their own
account to manufacture sensitive photographic plates by machinery, and
the operations are exceedingly delicate, for a single minute air
bubble or speck of dust on a plate may mar the perfection of a
picture. Their works for the purpose at Southgate were erected in the
summer of 1886, and were designed throughout by Mr. Alexander Cowan.

[Illustration: Fig. 1.]

Buildings of this kind have to be specially constructed, because some
of the operations have to be carried on in the absence of daylight,
and in that kind of non-actinic illumination which does not act upon
the particular description of sensitive photographic compound
manipulated. Glass and other materials have therefore to pass from
light to dark rooms through double doors or double sliding cupboards
made for the purpose, and the workshops have to be so placed in
relation to each other that the amount of lifting and the distance of
carriage of material shall be reduced to a minimum. Moreover, the
final drying of sensitive photographic plates takes place in absolute
darkness. Fig. 1 is a ground plan of the chief portion of the works.
In this cut, A is the manager's private office, B the counting house,
C the manager's laboratory, and D his dark room for private
experiment, which can thus be conducted without interfering with the
regular work of the establishment. E is the carpenter's shop and
packing room, F the albumen preparation room, G the engine room, with
its two doors; the position of the engine is marked at H. The main
building is entered through the door, K; the passage, L, is used for
the storage of glass, and has openings in the wall on one side to
permit the passage of glass into the cleaning room, M; this room is
illuminated by daylight. The plates, after
