Alb. Stille in Stockholm; this table is considered as attaining the highest
degree of perfection known.
The. Halda Watch Factory.
Scientific instruments (mathematical, optical, physical, etc.) made in
Sweden have attained a vers^ high standard of technical perfection.
Several of Fr. J. Berg’s instruments are renowned. Mention may be made
of the levelling instruments, constructed by the founder of the firm
and highly esteemed for their easy manipulation and strength. The
låte instrument-maker to the Royal Academy of Sciences, P. M.
Sörensen, of Stockholm, has manufactured a number of exceedingly fine
scientific instruments, among which may specially be remarked A. G.
Theorell’s meteorograph, which registers temperature, barometric
condition, and the velocity and direction of the wind, by means of an
automatic pressure apparatus, giving the result, not by means of curves, but of
ordinary figures. The apparatus, which is one of the most marvellous
of inventions, has come into use in several countries; for example, Brazil
has 4; but, on account of the considerable cost of manufacture, its more
general use is hindered. — The total number of factories employed in the
manufacture of scientific instruments amounted to 15 in 1912, employing
178 hands, and with a value of output of 420 600 kronor.
Among the watch and clock manufactories, mention may be made of
the Halda factory, illustrated above. Tn Stockholm there are the well-
