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 ————.
