^6 Ohfervaiioris u^nn an unnfual 



manner, all tlie phoenomena which he has obfervcd. But 

 effefts very different from thole- which have been defcribed 

 by Mr. Huddart are fometimes found to lake place. Thefe 

 I had an opportunity of obferving at Ranifgate, lad fumnier, 

 on Auguft the tirft, from about half an hour after four 

 o'ckx:k in the afternoon till between feven and eight. The 

 day had been extremely hot, and the evening was very fultry; 

 the Iky was clear, with a few flying clouds. I (hall defcribe 

 tlie phaenomena as I obfen,'ed them with a terreftrial tele- 

 fcope, which magnified between 30 and 40 times ; they 

 were vifible, however, to the naked eye. The height of the 

 eve, above the furface of the water, at which moll of the 

 obfervations were made, was about 25 feet ; fome of them, 

 however, were made at about 80 feet from the furface ; and 

 it did not appear that any of the phsenomena were altered 

 from varying the height of the eye, the general efle6l remain- 

 ing the fame. 



The firll unufual appearance which I obferved, was that 

 which is reprefented in Plate II. fig. i. Dire6ling my tele- 

 fcope at random, to examine any objeiSls which might happen 

 to be in view, I faw the top of the mafts of a fliip A, above 

 the horizon, xy, of the fea, as {liown in the figure; at the 

 fame time alfo, I difcovered in the field of view, two com- 

 plete images, B, C, of the fhip in the air, vertical to the fliip 

 itfelf, B being inverted, and C ereft, having their hulks 

 joined. The phrenoriienon was fo ftrange that I requefted a 

 perfon prefent to look into the telefcope and examine what 

 was to be feen in it, who immediately defcribed the two 

 images, as obferved by myfelf ; indeed they were ^o perfect, 

 that it was impoffible we could differ in our defcription. 

 Upon this, I immediately took a drawing of the relative 

 macnitudes and dlliances of the fliip and its images, which, 

 at that time, were as reprefented in the figure, as near as it 

 was poffible for the eye to judge; and it was very eafy to 

 cftimate them to a very confiderable degree of accuracy. As 

 the (hip was receding from the fliore, lefs and lefs of its malls 

 became vilible ; and, continuing my obfervations, in order 

 to difcover whether any, or what variations might take place, 

 I found that, as the ihip defccnded, the images B,C afcended; 



but.
