Table VII. exhibits the velocity of the wind in miles and its direction in points (1-32). T velocity is measured from half an hour before to half an hour after the hour named, but the directi is read off at the hour.
Table VIII. exhibits the amount (0-10), name (Howard's classification) and direction whe
Where the names of upper and lower clouds are given, but only one direct coming of the clouds, this refers to the lower clouds. With regard to the naines of clouds nimbus (nim) is only enter when the rain is seen to fall; when no rain is seen to fall cumulo-nimbus (cum-nin) is entered, as this name is also used to indicate clouds intermediate between cumulas and nimbus. Cumulo-strat (cum-str) is the well known thunder cloud, and strato-cumulus (str-cum) signifies a cloud intermedig between stratus and cumulus.
Table IX. exhibits for every hour in the day the mean velocity of the wind reduced to 4 as wa as 2 directions, according to strictly accurate formula, and also the mean direction of the wind.
Below this is printed a list of the phenomena observed.
17. The following annual Weather Report for 1897 is arranged as follows :-
Table VI. exhibits the mean values for the year (or hourly excess above this) obtained from monthly reports. The total duration of rain was 1036 hours. There fell at least 0.01 inch of mi on 166 days.
Table VII. exhibits the number of hours during a portion of which at least 0.005 inch of nå (or dew) was registered.
Table VIII exhibits the number of days with wind from eight different points of the compus The figures are obtained from the mean daily directions in Table VII. of the mouthly reports. Day with wind from a point equi-distant from two directions given, are counted half to one of these half to the other, e.g., half of the days when the wind was NNE are counted as N, and the other is as NE.
Table IX. exhibits the number of days on which certain meteorological phenomena were registered and also the total number of thunderstorms noted in the neighbourhood during the past year.
Table X. shows the frequency of clouds of different classes.
Table XI. is arranged as last year.
Table XII. exhibits the monthly and annual extremes. The extremes of humidity and vapor tension are only approximate as the hourly values are not calculated.
Table XIII. contains five-day means.
Tables XIV., XV., XVI. contain magnetic observations.
18. Observations of magnetic declination and horizontal force were made with the auth magnetometer Elliott Brothers, No. 55, and the dips were observed with dip-circle, Dover No. 71.
The methods adopted in making the observations and in determining and applying the correcikl
"On the verification are explained in Appendia G. of Observations and Researches meide in 1885:
the unifilar magnetometer Elliot Brothers No. 55." The value of log 2 K was 3.44905 at 24°. T value of P was +5.818. The mean value of the magnetic moment of the vibrating needle was 0.448) in English units and 585.84 in C.G.S. units.
The times of vibration exhibited in the table are each derived from 12 observations of the tiss occupied by the magnet in making 100 vibrations, corrections having been applied for rate of chronousl and are of vibration.
The observations of horizontal force are expressed in C.G.S. units (one centimeter, one gramin one second), but the monthly synopsis exhibits X, the horizontal, as well as Y, the vertical, and to forces, which have been computed by aid of the observed dips, and their values are also given in Englis units (one foot, one grain, one second) and in Gauss's nuits (one millimeter, one milligram, one second
