APPENDIX V. A. T I D A L S U R V EY. |By ('. E. Adams, M.Kc. K.R.A.S.] Harmonic ANALYSIS. The records for the year beginning 1908, December 1, of the Auckland self-registering tide-gauge have been harmonically analysed from the hourly ordinates measured to the nearest one-eighth of a foot, using the tidal abacus of Sir G. H. Darwin, X.C.8., F.R.S. The period for the analysis was selected to give as complete a series of observations as possible, the total breaks in the record aggregating about six days> and ranging from five hours to two days. The missing records were interpolated, using the method described in last year's report. The scales of the Auckland tide-record were— vertical 1 in. to 1 ft., and horizontal, 1 in. to 1 hour. Generally, the same methods and equal care were taken as in the analysis of the Wellington records, and the whole work was done in duplicate. It is hoped therefore that no serious errors remain undetected.
