Local DescriptionFair to good condition. Pages are clean, sound. Inscription on front inside cover. Cover is faded, especially on spine, and spine has some rubbing at edges. Tanning marks on first and last pages and on page edges, but does not obscure text. Description"Means of working a Sun "Chronometer" arithmetically have been for many years a desideratum. The book, as a substitute for or a check on logarithmic calculation, is almost a necessity, and is especially useful in latitudes less than 46. A comparison has been made in actual work of the tabular results with those obtained in the ordinary way, showing practically identical results'." |
