10 The Rev. W. SCORESBY on some remarkable 



ern part of Bridlington Bay) was slightly influenced by the same 

 refraction. The air on this occasion was clear and calm, occa- 

 sionally there was a gentle sea-breeze. 



Twelve days after this (June 24th), the phenomena were re- 

 peated with several new peculiarities, especially in regard to the 

 land, as hereafter noticed. The interval between the true and 

 refracted horizons (measuring between one and two minutes of a 

 degree) was, as before, of a bluish-grey colour, and resembled a 

 thin mist. But, besides the usual appearances of the ships, there 

 were many erect images perched, as it were, upon the upper line 

 of the horizon, and belonging to vessels that were evidently far 

 out of sight ! This occurred at noon, when the temperature was 

 80 in the shade. In the afternoon, the temperature becoming 

 more equable, most of the phenomena disappeared ; but in the 

 evening, with the change of temperature, they were renewed in 

 their principal varieties. On this day the sky was again cloud- 

 less, with a slight breeze from the eastward, though occasionally 

 it was quite calm. 



The following day there were very beautiful repetitions of 

 the phenomena. The upper horizon was occasionally double and 

 broken. A second erect image, of some of the ships, appeared 

 between the two upper lines. 



Again, there was a renewal of these interesting appearances 

 on the 26th of June. The day was, as before, clear and hot ; 

 but with a smart sea-breeze. The horizon began to separate 

 about 10 A. M., and between 11 and 12, every object at sea, be- 

 yond the distance of six miles, became influenced by the une- 

 qual refraction. There were, on this occasion, several instances 

 of a single inverted image of a ship, clearly defined, though the 

 ship to which it referred was altogether out of sight ! 



Two or three days after this I left the coast, and had no 

 other opportunity of looking out for these phenomena until the 

 middle of August ; and after that time I could never perceive 

 any recurrence of them.
