exhibit a class of watches possessing many elements of merit, and

of superior finish in many respects and at a cost which is quite

reasonable. That the watches are constructed upon scientific

principles and are intended as reliable timepieces, is shown from

Observatory tests. The variations show that care has been taken to

approximate a perfect adjustment, and that a partial success has

been attained. A peculiarity in the construction of the balance

wheel--having a horizontal split from the timing second holes each

way--is noticeable, which we fail to understand. This exhibit was made

expressly for this Exhibition, and Observatory rates sent with each

watch, and, as a representative exhibit, although small, was the

second best examined, and is, in its class, of the first order of

merit, and adjudged a first-class award.
