HISTORY OF THE
[1830-40
in the then recently discovered art of photography. While the
telescope was yet standing, John Herschel secured a photograph
of it, using a glass negative, which is still in existence and from
which paper prints were successfully made many years later. *
How many glass negatives have been taken since then to depict
the stars and nebulae, first systematically explored by the two
Herschels ? It was fitting that what became afterwards a powerful
adjunct to astronomical telescopes should first have been fashioned
by a Herschel, and should first have been directed to the earliest
of modern giant telescopes.
Of private observers with more modest instrumental means
at their disposal, there were as yet very few. Instruments from
the collection formed by the Society were freely lent to such
Fellows as were expected to make good use of them. Among the
earliest donations to this collection were a 4-foot transit instrument
and a small altazimuth, given by the son of Colonel Beaufoy.
These were lent to Captain W. H. Smyth, R.N., who had won a
name by long-continued hydrographic work in the Mediterranean,
and on leaving the sea had settled at Bedford. The altazimuth
was soon exchanged for another (by Troughton) presented to the
Society by Dr. Lee. But the most important instrument in Smyth’s
Observatory was an equatoreally mounted refractor by Tulley,
of 5 9 inches aperture and nearly 9 feet focal length, mounted in
1830, and supplied with a clock movement designed by Sheep
shanks. With this, Smyth, during the next nine years, measured
hundreds of double stars and examined clusters and many of the
brighter nebulae. When he had completed these observations,
Smyth parted with his telescope to his friend Dr. Lee, who erected
it in an observatory he had built at Hartwell House, Bucks.j*
Here it seems to have been only occasionally used ; but though
never engaged in regular astronomical work, Lee was a generous
patron of science on many occasions and very liberal to our Society,
as we shall see further on.
Another private observatory in the early thirties was that of
Thomas Maclear, at that time a physician at Biggleswade, Bed
fordshire, J where he observed and computed occultations and
other phenomena. But his activity there was not of long duration,
as he was appointed to succeed Henderson at the Cape in 1833.§
* The writer is indebted to the late Sir W. J. Herschel for one of these
prints, mounted in a frame made from the ladder-rungs of John Hersehel’s
20-foot telescope. The negative is in the South Kensington Museum.
f Hartwell House had been a very well-known place early in the century,
as Louis XVIII. lived there from 1808 to 1814.

§ It is not a little remarkable that, of four Directors appointed to the Cape
Observatory in fifty years (1830-80), three had already acquired a name as
amateurs.
