P.S. I received some years ago, through the R.A.S., № 5 of the Numbers of
your "Memorie" and dated 1859, containing Measures of Double Stars, pages 33 to 40;
and I earnestly looked for succeeding numbers,—but none arrived, or at least,
were forwarded to me. My excellent old friend, Admiral Smyth tried about
2 years ago, to get the Volume for me, but without success.— He lives about
four miles from me.— The volume was lent me for a few days by
a friend who had procured it in Rome; and in looking over the measures
of double stars I found that under the Star ξScorpee A and B (erroneously
included by Flamsteed in Libra, and termed by him 51 Libra and ξLibra,—which
has caused much confusion),—you have done me the honour of quoting an
observation of mine dated 1834·5; but the distance is quoted 1"·66 instead
of 1"·166. This is of some importance—See Memoirs R.A.S. Vol xix.p.199
which you have referred to. My measurement was made with the same
5-foot refractor by Dollond, with which I first saw the solar granulations.
Hence you may judge of its equality.—I also measured with it ζ Cancri,
A and B.—P=30°·8 - Dist. 1"·09; 1831·30. This star I have observed these two years
with my 8-inch refractor—
1864·29-P=253·18; D=0"·707; on 2 nights
1865·30 243·42; —0.631; — 3 ————.
