which, when measured on the cord is equal to 45 miles. The letters A. B. C. &c., on the line A. G. correspond to the same letters on the broken curve, marking the ship’s track on the starboard tack, and point out the particular part of the storm that passed over the ship in her place on the curve, as indicated by such corresponding letter. The line A.G. also shows the ship's track through the last half of the storm-circle, and measures 314 miles corresponding toa distance on the cord equal to 300 miles. The diameter of the storm-disc is computed at 588 miles, and its rate of travelling 8.4 miles per hour.
It is here made evident that the “Argyleshire” passed through a distance in the storm-circle equal to 530.7 miles, contained within an angle of 115°, the cord of which runs nearly parallel with the course of the gale and measures 496 miles. The “Argyleshire,” during the first half of the gale experienced the winds, as follows: N.N.E., N.N.E. 18 E., N.N.E. 14 E., N.N.E. 12 E., N.N.E. 34 E., when the ship was hove to on the port tack, and the wind soon began to veer more rapidly, and in a short time veered to N.E. 12 N. The reason why the wind veered so slowly previous to heaving to was because she was running nearly direct for the centre, and therefore chaning the bearing of it but slightly; and this circumstance ought to have attracted the attention of the captain to his mistake in supposing the gale to travel to the Northward; for in that case, running as he was to the S’d and E’d, he should have changed the wind to the left—that is—from N.N.E. to N. by E. N. N. by W. N. N. W. &c. &c. &c. until eventually, when he should have reached the Southern portion of the Storm-disc, he would have had the wind from the W’d, and gradually changing to the S’d and W’d.
