Iguana, the back of the animal was armed; but at the same time he 

 mentioned many anatomical peculiarities, which led him to hesitate 

 in determining positively that these bones had formed such appen- 

 dages. He next entered upon a careful examination of the reasons 

 why they could not be processes of the vertebrae. Many dermal 

 bones, which served to support the large scales, were discovered by 

 the author in the stone. The author proposed forming a new genus 

 for this animal, the characters of which would depend on the pecu- 

 liarity of the sternal apparatus and the spinous processes ; and he 

 suggested the name of Hylaeo.saurus, or Forest-Lizard, to indicate 

 its locality, the Forest of Tilgate. In the conclusion of this memoir, 

 the author made some observations on the character of the district 

 at the Iguanodon era. FYom the condition of the organic remains, 

 which with the exception of the beds of shells, and the vegetable 

 stems of the fossil Equiseta Lyellii, bore marks of transport, he 

 contended that the river which had formed the ancient delta, the 

 Wealden of geologists, must have had its source far distant from the 

 beds which it had formed ; and from the state of some of the spe- 

 cimens (and he instanced particularly that of the Hylaeosaurus), he 

 inferred, that the bones of the reptiles must have been broken and 

 dislocated while covered with muscles and integuments, otherwise 

 the broken parts and the displaced bones could not have maintained 

 the relative situation in regard to each other which they are now 

 found to maintain. He concluded with an eulogium on the late 

 illustrious naturalist Baron Cuvier, many of whose observations, 

 from his correspondence with the author, were introduced in various 

 parts of the memoir.

SINGULAR FOG-BOW SEEN ABOVE OLD MELROSE. 



ON the evening of Monday the 12th of November between 1 1' 1 and 

 I2' 1 p.m. there was seen from Gateheugh near Bemerscale, a 

 very luminous fog- bow, produced by the reflexion of the moon's rays 

 from the globules of water suspended in the air, and constituting a very 

 dense fog which extended over the whole valley of the Tweed from 

 Old Melrose up to Ahbotsford. Owing to the state of the moon, the 

 colours of the bow could not be recognised. 



The bow was extremely luminous, and every part of the arch was 

 distinctly seen. It was thrown like an arch over the peninsula of 

 Old Melrose, and, in one position of the observers, its two extre- 

 mities appeared singularly luminous, which arose from their happen- 

 ing to coincide with the two branches of the river, above which the 

 fog was more dense than above any part of the ground. 



A little above the south side of the bow, the Eildon Hills raised their 

 triple crown, entirely free from haze, and finely illuminated by the 

 moon, like a distant island in the ocean of fog which had settled round 

 their base.
