Mr. J. B. N. Hennessey. 



[May 25, 



October 11. — Wind in low puffs from S. Air and sky beautifully clear, except 

 occasional small patches of c.c. which kept rising to W., and floating up to some 30° 

 of sun, when they became invisible and could no longer be followed. 



October 12. — As on 11th ; except that the small patches of c.c. passed along a 

 track some 8° to 20° below sun. 



October 14. — A very favourable day. Light wind from S. Not even a speck of 

 cloud visible ; light haze towards plains S., and also slightly visible by dimming 

 hills to N. 



October 15. — A very favourable day and exactly like 14th, with one exception, 

 i.e., small light c.c. floated up from W. in a course passing some 15° to 25° below 

 sun and disappeared when some 30° W. of sun. Wind S., at first very low, later on 

 in somewhat fresh puffs. 



October 16. — A very favourable day, except that c.c. (from very small up to 10° 

 in diameter) kept passing at intervals in a track 10° to 20° below sun. Haze over 

 plains more than yesterday, but no increase up here. 



October 17. — A very still day, very clear, but small c.c. keep occasionally floating 

 W. to E. in track about passing through sun ; invisible near sun. Haze over plains 

 rather increased since yesterday ; haze is not visible overhead. 



October 18. — Sky clear but for small c.c. floating about and disappearing 15° to 

 40° from sun ; haze over plains increased. Hills some 30 miles to S. just visible ; 

 to JN". view fine and clear. Wind S., in gusts but not strong. It is impossible to 

 say how far, if at all, the clouds interfered. 



October 19. — Sky beautifully blue and clear, but observation spoiled by a few 

 patches of c.c. floating W. to E. across sun from time to time. Haze to S. over 

 plains. A thunderstorm to N. last evening. Wind S. and low. 



October 20. — A very fine day marred by not more than half-a-dozen c.c. floating 

 about, some of which interposed. Sky otherwise blue and clear. All doubtful ob- 

 servations rejected. Wind in rather fresh gusts and southerly. Observations 

 rejected when c.c. visibly interposed. 



October 22. — A most brilliant day. Sky blue and without cloud or haze. Wind 

 S. and rather fresh. 



October 24. — Sky beautifully clear, except half-a-dozen small streaks of cir-strati 

 about 10° above S. horizon, far from 0. Wind S. and sometimes in gusts, other- 

 wise day highly favourable. 



October 25. — Day beautifully fine. Wind S. and in gusts low and fresh. 



October 26. — Day beautifully fine : two or three (only) small patches of c.s. 

 moving W. to E. some 25° below sun. Wind S. and in rather strong gusts. 



October 28. — To-day is peculiar. Strati and cumuli run along horizon for some 

 10° height from S. by E. and N. to S.E., besides a few small cirri to N. some 60° 

 from sun ; and in addition a few small c.c. kept floating up from W. to some 25° of 

 sun (in track which would pass say 15° to 20° under sun) and then disappeared. 

 Wind S. and in rather fresh gusts. No visible clouds approached the sun. Sky 

 generally blue and bright. 



October 29.— Sky deep blue, for about 10° below to 7° above sun. A little haze 

 .to S. over plains, c.c. along horizon from S.E. to N.W. A most perfect day for 

 observations. 



October 30. — Day beautifully fine. Not a speck of cloud except some cumuli on 

 the snows (N) up to some 4° altitude only. Wind S. and occasionally in fresh 

 gusts. Haze (smoke, vapour, and dust) over plains to S., but hills to N. quite clear. 

 Weight for day 1 - 0. 



October 31. — Day beautifully fine, as nearly as possible like yesterday (30th) , 

 except wind slightly stronger and haze over plain slightly increased.
