It appeals especially to Colleges and Schools for Demonstration purposes.
The construction is on that of the well-known" Fortino principle. The level of the cistern mercury is reducible to zero, in exactly the same manner as in the more expensive forms.
The diameter of the mercurial column is 25 inch, and affords a bold, well-defined reading. The scales, by means of the double vernier, are capable of being read to 'or inch and '1 millimetre. It is mounted on a wellpolished, solid mahogany board, with plates for attad. ment to wall, opal glass reflectors for reading off, and screws for vertical adjustment.
The metal portions are all well bronzed and lacquered, and the scales are silvered brass.
We confidently recommend this Instrument for ose as "Standard" in Colleges and Schools, private Observa. tories, and by Gas and other Engineers. Price, complete, mounted as illustrated,
£3 7 6 each, or may be had with one scale (either inches or milli metres), and with thermometer on other scale, at sans price.
