Anemonal Curves during Nov. Dec. and Jan. 1836-37. 211 



the river ; and they also thought, by the appearance of fish 

 on the Corrie River, that more salmon were also there than 

 what we carried up this season ; and, after I returned, the 

 watchmen saw a large salmon near the foot of the Fiag ; but 

 those which they formerly saw were some miles up the river. 

 Therefore we can no longer doubt of the salmon returning to 

 the same rivers where they spawn or were spawned ; and that 

 each river has a particular breed of salmon of its own also." 



Art. IX. On the Anemonal Curves described during November 

 December, and January, 1836-37. By R. Birt, Esq. 



Upon carefully observing and tabulating the direction of 

 the wind, we find it describes various curves, and exhibits, to 

 a certain extent, a degree of regularity which, perhaps, may 

 not be generally suspected ; especially as the wind is usually 

 employed to represent fickleness and inconstancy. It is not 

 my intention, on the present occasion, to draw any conclusions 

 from the anemonal phenomena hitherto observed, but simply 

 to lay before the reader the facts that have come under my 

 observation during November, December, and January last, 

 and point out the probable utility that may arise from an 

 accumulation of observations arranged in a similar manner. 



I shall present the reader with the observations arranged 

 in the form of curves, which are obtained by regarding the 

 direction of the aerial currents as ordinates, the east point 

 being, in the present instance, zero. During the months of 

 November, December, and January, three well-marked curves 

 were described ; the first (Jig. 20. 1.) extending from Oct. 31. 

 to Nov. 22. ; the second (Jig. 20. 3.), from Dec. 1. to Dec. 23. ; 

 and the third (Jig. 20. 5 and 6.), from Dec. 30. 1836, to Jan. 

 25. 1837. On Oct. 31. the wind was observed from north by 

 west ; and it had a tendency to approach the south-east point 

 during the next eleven days, it being observed in that direc- 

 tion on Nov. 11. The continuous line exhibits the actual 

 curve described, while the dotted line shows the general 

 tendency of the wind. After Nov. 11., the tendency is re- 

 versed, the direction of the dotted line being from south-east 

 to north by west during the next eleven days. On Nov. 22. 

 the wind was observed from the latter point. 



The curve described during December is, in many respects, 

 similar to that observed in November, particularly in the 

 direction being south-east on the eleventh day from its com- 

 mencement, and its subsequent approach to the north point. 

 One of the most interesting features of these curves is their
