The display of marine chronometers by this maker, with the Observatory
ratings, was of the very first order. Every part of those instruments
was remarkably well made, and the modifications of some of the balance
wheels worthy of special attention. Adjudged a first-class award.
The display of watches by the same maker, although small, commanded
attention from their very nice finish in all parts. As will be seen
from the report and diagram of Professor Russell, they are good
timekeepers, especially the one having the chronometer escapement.
This style of watch, however, is of too delicate construction and too
costly to fully meet the requirements of any considerable public want.
The same objection will hold good as to the lever escapements as far
as cost or economy is concerned, they being comparatively too high
priced. Representing a certain class of manufacture, they are of the
first order of merit, and adjudged a first-class award.
The "gas governor" exhibited by the same maker, an instrument for
regulating the amount of heat in the testing of chronometers, is
commended as a useful invention.
