CHRONOMETERS, 
WATCHES and CLOCKS, have long held 
pre-eminent rank, as may be seen from 
Reports of various scientific persons :— 
THE ASTROMOMER ROYAL (Sir G. B. AIRY), in his Report 
to the Admiralty (13th of August, 1870) on forty Chronometers i 
entered for annual competition, says of M. F. Dent’s Chronometer :— 
“THIS IS THE FINEST CHRONOMETER WE HAVE EVER 
HAD ON TRIAL.” 
N.B.—The late Astronomer Royal (J. Pond, Esq.), reporting, in 1829, on the 
celebrated public trial, by order of the Lords of the Admiralty, which lasted thirteen 
years, during which nearly five hundred Chronometers were tested, says :— 
“ Your Chronometer, No. 114, is entitled to the First Premium. Actual variation 
in the year, 54-hundredths of a second. This is superior to any other yet tried.” J 
THE RUSSIAN IMPERIAL ASTRONOMER (M. struve, 
of St. Petersburg), reporting upon eighty-one Chronometers tested 
by the Russian Chronometrical Expedition in 1813, says:— 
“The Dent Chronometers have held first rank in a brilliant manner 
They contributed, beyond dispute, the most effectually to the exactitude 
of the results. “ m. STRUVE.” 
%* By Command of the Emperor , the Russian Gold Medal of the Highest Order of Merit 
was presented to Mr. DENT. 
SIR H. M. STANLEY’S TESTIMONY. 
To the excellence of Chronometers supplied to him by M. F. Dent, 
and used in finding his longitude in his last Expedition, Mr. Stanley 
says in a letter, 5th duly, 1890 : — 
“ The Chronometers supplied by you, and which were taken across Africa 
in ir y late Expedition, proved of very great service to me, and were in every 
way thoroughly satisfactory and reliable.”
