28 EIGHTH REPORT — 1838. 



Tables, fyc, of Observations made with Professor Whewell's 

 Anemometer at Mount Tfise, Devonport. From November 

 1837 to June 1838, inclusive. 



These Tables comprise: — 1. The observations as daily re- 

 corded. 2. The reduction of these observations. 3. A sum- 

 mary Table, in which the general result is condensed. Lastly, 

 The charts and general type of the wind, as shown by the re- 

 spective reductions and summary. 



Plate 13, contains the general summary : the month of No- 

 vember 1837 is coloured blue, and marked 11 ; December is red, 

 and marked 12 ; January 1838 is again blue, and marked 1. The 

 remaining months continue to be marked 2, 3, &c. The breaks 

 in the continuation of the lines show when the instrument was 

 under repair. The direction of the wind is here only recorded 

 and indicated by dotted lines. 



The black dotted lines show the resultant magnitude and di- 

 rection for each month ; the five black lines are continued re- 

 sultants, viz., that marked 1, 2, is the resultant of 11 and 12, 

 that marked 1, 2, 3, of 11 and 12, and so on to the last marked 

 1 to 8 ; which is the resultant of 8 months. The scale of this 

 Plate is that of the 400 equal parts to the inch.
