 29.47 ; at midnight 29.45 ; ship running S. W. to 3 p. m., then South, 5 to 7 

 knots, to midnight. 



13th October. — Blowing fearfully from N. N. W. (11) with torrents of rain 

 more like hail, but we cannot say if it was so, the atmosphere appears closed in 

 as dark as possible although moonlight ;3a.m. wind N. W. b. N. (10), 6 a. m. 

 N. W. (7), N. W. b. W. (8), 9 W. N. W. (8) and at 11 W. b. N. (8). At 4 

 if possible much worse weather in the squalls, lost a Jolly boat. By 8 less wind 

 but so fearful a sea that we cannot haul the ship to the wind yet. Noon more 

 moderate, but the same sea, ship running to the South and S. E. Noon Lat., 

 by Acct. 17° 17'; Long. 88° 5. The Barometer as follows; 1 a. m. 29.48; 

 at 2 to 4 2942, 29.37, 29.40 ; at 5, 29.45; at 6, 29.50; at 7, 29.51 ; at 8, 

 29.52; at 9, 29.55; at 10, 29.56; at 11, 29.57; and at noon 29.57. p. m. 

 moderating, made a little sail, a dark heavy leaden bank of clouds away to the 

 N. b. W. ; a cross confused sea lifting the ship up and then letting her fall 

 as if it would jerk the masts out of her. To midnight wind from West to 

 S. W. and S. W. b. S. ; at 10 p. m. heavy squalls with dreadful thunder and 

 lightning. At midnight moderating fast. 



OntheUth Oct. — The weather became fair. Noon Lat. Obs. 17° 15'; 

 Long. 88° 26'.

-To this very valuable log Captain Andrew adds, in his remarks in a 

 letter written from Aden, " I do not think we were within the revolving 

 disk till we got the wind at N. N. E. Consequently I do not think 

 by any manoeuvre I could have got better weather than I had. I made 

 a sort of diagram at the time and made the track of the Cyclone about 

 N. W. b. W. J W."
