II. A Description of some Remarkable Effects of Unequal Refraction, observed at Bridlington Quay, in the Summer of 1826

Extract

In the session of 1820–21, I had the honour of communicating to the Royal Society, a description of some remarkable atmospheric refractions observed in the Greenland Sea. Since that period, additional opportunities for observation, under circumstances peculiarly favourable, afforded a great number of other examples of a similar kind, along with some still more singular. Among these, the most extraordinary was the inverted image of a ship, which appeared in the lower part of the atmosphere, so distinctly and beautifully defined, that I could venture to pronounce it to be the representation of my father's ship, as, indeed, it proved to be, though we were then distant from each other about 28 miles, and some leagues beyond the limit of direct vision. But an account of the principal of these extraordinary appearances is already before the puplic, and I merely allude to them, in consequence of their similarity to the refractions I have now to describe, that occurred upon our own coasts.

These phenomena occurred during the last summer about Bridlington Bay, and were seen from my residence at Bridlington Quay.
