(Nos. 233(a) to 247(a).) Addendum to Zone No. 8.-Continued. RELATIVE PREVALENCE AND FORCE OF WINDS FROM THE DIFFERENT POINTS OF THE COMPASS. Ratio of resultant to sum of winds. ZONE No. 9. LATITUDE 45° To 50° NORTH. The data for the study of the winds of this zone consist of observations made at 342 permanent stations on land, where the observations were regularly recorded, or during journeys and travels, where, for the most part, only a transient sojourn was made at any one place, for an aggregate period of over 1696 years; and for about 17 years at sea. The distribution is as follows: Computed from observations for an aggregate period of six years, collected and classified, from the logs of numerous sailing vessels, at the United States Naval Observatory, under the direction of Capt.
