HERSCHEL'S TELESCOPE.

(_To the Editor of the Mirror._)

Your article on the "Patrons of Astronomy," in the Mirror, No. 328,

brought to my recollection the following anecdote, for the truth of

which I can answer, having received it from Mr. Watson, well known as

the most celebrated private optical instrument maker in Europe, and at

the time living on intimate terms with the late Mr. Arnold, the most

eminent watchmaker of the day. When the late Sir William Herschel's

great telescope was first exhibited at Slough, among other scientific

men who went to see it was Mr. Arnold, who took Mr. W. with him. Neither

of them thought much of it, though it was praised by the multitude; as

it was, with its constructor, patronized by the late king and his

consort, for Herschel was a German, as you well know. A few astronomical

amateurs, who thought as Mr. Arnold did, proposed to Mr. Adams, of

Fleet-street, then astronomical instrument maker to the king, (by whom

Mr. Watson was employed,) to get Watson to make an instrument in

opposition to Herschel's. The order being given by Adams, Watson set

about the work, and had made some progress in the construction of the

instrument, when the circumstance found its way to the ears of royalty.

Orders were immediately sent to Mr. Adams to put a stop to the work, or

he should no longer be optician to the king. Watson did not proceed, but

could never learn the cause of the counter-order, till after a lapse of

several years, when a stranger called on him, in Valentine-place,

Blackfriars-road, and after putting several questions to him about his

instruments, related to him the cause of the counter-order; upon which

Mr. Watson showed him the progress he had made, and which I have also

seen. This story I heard related by Mr. Watson at a dinner party at Mr.

Arnold's, at Well Hall, near Eltham, where were also Mr. Dollonds, and

Mr. J. R. Arnold, the son.

Our Correspondent will perceive that we have qualified some phrases of

his letter, but that all the facts appear.

The _Quarterly Review_, No. 75, from which our notice was taken, is

tolerably plain upon the lack of patronage towards astronomy in this

country, and seems disposed, in enumerating the state of astronomical

knowledge in civilized Europe, to place Great Britain beside Spain or

Turkey![4] We chance to know that one of the most able and enterprising

astronomers of the present day relinquished a lucrative profession, that

he might be more at leisure to indulge his philosophical pursuits; so

that, if patrons be wanting, this apathy does not appear to have

entirely destroyed the taste for the divine study. This gentleman, in

concert with another, ascertained, in the course of three years, the

position and apparent distances of 380 double and triple stars, the

result of about 10,000 individual measurements, and for their Memoir,

they received the astronomical prize of the French Academy of Sciences.

In the following year, the former individual communicated to the Royal

Society the apparent distances and positions of 458 double stars, of

which 160 had never before been observed.

[4] We feel as if it were a species of treason to record the

fact, that, within the wide range of the British islands, _there

is only one observatory, and scarcely one, supported by the

government_! We say scarcely one, because we believe that some

of the instruments in the observatory of Greenwich were

purchased out of the private funds of the Royal Society of

London. The observatories of Oxford, Cambridge, Dublin,

Edinburgh (except a grant of 2,000_l_.), Armagh, and Glasgow,

are all private establishments, to the support of which

government contributes nothing. The consequence of this is, that

many of them are in a state of comparative inactivity; and none

of them, but that of Dublin, have acquired any celebrity in the

astronomical world. Such, indeed, was the state of practical

astronomy in Scotland, that within these few years, a Danish

vessel, which arrived at Leith, could not obtain, even in

Edinburgh, the time of the day for the purpose of setting its

chronometers.--_Q. Rev._

Of course, our correspondent does not impeach the talent of HERSCHEL;

but it is lamentable to reflect that no attempt has been made to repeat

or extend the labours of that indefatigable astronomer.--ED.
