At 8h. 40m. the Superb was gaining fast upon us, and the Admiral ordered me to hail Captain Keats, directing him to engage the ship nearest to the Spanish shore. the three French ships in the van, the Spanish squadron in the rear.
Deduct this volume from the amount of permanganate solution used in the titration. From the data obtained, calculate the relation of the permanganate solution to the normal. The reaction involved is: 5Na C O + 2KMnO + 8H SO > 5Na SO + K SO + 2MnSO + 10CO + 8H O !Method A!
On this he writes: "This gentleman has figured so prominently in our national affairs for the last few years, that it may not be out of place if I give a few remarks on his horoscope. The time of his birth is stated to have been January 17th, 1863, 8h. 55m. A.M., but neither myself, nor other Astrologers, are satisfied with this hour. I think he was born some minutes sooner.
At 8h. it fell calm; at 8h. 20m. the Pompée and Audacious, bringing up the breeze, passed us to windward, when the enemy's ships opened their fire on us; at 8h. 14m. a light air sprung up, passed the Audacious to leeward, at which time the Pompée and Audacious opened their fire; at 8h. 20m. the breeze dying away, came to with the sheet-anchor, as did the Pompée and Audacious, hove in the spring; and at 8h. 30m. opened our fire on the French Admiral's ship: at 10h. the Cæsar anchored on our bow, and sent a spring on board of us; at the same time the action became general, and the Hannibal got on shore, after attempting to cut off the French Admiral's ship.
P.M. up mainsail and in royals; at 2h. made the signal for the squadron to prepare for battle, and, anchoring, bent the sheet cable through the larboard gun-room port to the sheet anchor; at 4h. set steering-sails, fresh breezes and fair; at 8h. moderate breezes, Cape Moulinau E.N.E. seven or eight miles; at 12h. At 12h. 30m.
As soon as it was finished, my uncle took from his pocket a notebook destined to be filled by memoranda of our travels. He had already placed his instruments in order, and this is what he wrote: Monday, June 29th Chronometer, 8h. 17m. morning. Barometer, 29.6 inches. Direction, E.S.E. This last observation referred to the obscure gallery, and was indicated to us by the compass.
I forced myself, therefore, to sup and to slumber, resorting for the first time in many years to the stimulus of brandy for the one purpose, and to the aid of authypnotism for the other. When I woke it was 8h. by my chronometer, and, as I inferred, about 5h. after midnight of the Martial meridian on which I lay.
Mistakes of this sort are easily made and constitute one of the most frequent sources of error. 5Na C O + 2KMnO + 8H SO > 5Na SO + 10CO + K SO + 2MnSO + 8H O.
At 8h., I employed for the first time the apparatus which I may call my window telescope, to observe, from a position free from the difficulties inflicted on terrestrial astronomers by the atmosphere, all the celestial objects within my survey. As I had anticipated, the absence of atmospheric disturbance and diffusion of light was of extreme advantage.
The correction is given by the following table Thus at a port where the establishment was 3h. 25m., let us suppose that the transit of the moon took place at 6 P.M.; then we correct the establishment by -60m., and find the luni-tidal interval to be 2h. 25m., and accordingly the high water takes place at 8h. 25m. But even this method is only an approximation.
