Quarter cloth. Condizione: Fair. Condizione sovraccoperta: No dj. First Edition. Presentation inscription, "Presented by Order of the Syndicate of the Cambridge Observatory to the Observatory at Glasgow". The handwriting does not appear to match another sample of Challis' writing we have seen. Front hinge sprung, holding by one binding tape. Rear hinge the same. Pages clean, minor foxing to prelims, general shelfwear and splitting to cloth , basically a wreck but text block firm. With Glasgow Observatory stamp to title page. Mostly transit observation tables, rear section contains observations in 1848 of the recently discovered Neptune, in the prior search for which Challis played a role. He had actually recorded Neptune twice, a month before its official discovery date in September 1846, but did not follow up with charts and make the connection. This volume contains transit observations from the month in question, though not the Neptune record. Quite a detailed section on the reduction of the observations, which makes more interesting reading than the observations themselves. LXIX+357pp. Size: Folio.

green cloth. Condizione: Fair. Condizione sovraccoperta: No dj. First Edition. Presentation inscription, "To the Observatory at Glasgow from the Author" not signed, but handwriting does not match another presentation sample of Challis' writing we have seen. Either one could be real or written by a proxy, and it was common in those days to have a copperplate style and plain style which could look very different from the same hand. Front hinge sprung, rear hinge firm. With Glasgow Observatory stamp to title page. Green cloth spine very shelfworn, paper covered boards very grubby and shelfworn. Acceptable reference copy and could be re-backed or re-cased as the text block is sound. Mostly transit observation tables plus a detailed section on reduction techniques. lxiv+2pp corrigenda+160pp. Size: Folio. Signed by Author.
