Abstract
THE errors found in the British tide-predicting machines referred to in the article were more serious than those described by Mr. Manner. The machines were of the curve-tracing type, and therefore inevitably less accurate (with the time and height scales ordinarily used) than direct-reading machines; they had zero errors, and also diminished the apparent range of the tide. The direct-reading machine used by Mr. Marmer is both more accurate and quicker in use; for manv purposes, though perhaps not for all, such a machine is a valuable substitute for numerical computation.
