feet. All these gliding animals inhabit trees, and it is a life among 

 trees that makes their power of taking very long gliding leaps of 

 use to them. The flying fish is another animal with imperfect 

 power of flight, but it is not a gliding animal, according to Mr. 

 Wallace, an excellent observer — it really flies. Birds have no 

 vestige of a side membrane, and therefore most probably never 

 were gliding animals, but moved their wings from the first, as also 

 did insects. 



On Wednesday evening, 15th December, Mr. W. J. Knowles 

 read a paper, entitled, " Works of Art found in the Boulder Clay 

 at Cullybackey." He described a number of curiously-shaped 

 stones found in a road-cutting, at a depth of 18 feet, near Cully- 

 backey, a few years ago, some of which were so perfectly formed 

 that they looked like works of art ; also, some stones of nearly 

 similar shape found in a well sunk for the Rev. Mr. Gray, in the 

 end of the past Summer, at the U. P. Manse, Cullybackey, and a 

 piece of wrought wood, found in the same well, at a depth of 32 

 feet. The stones found in the cutting are of soft, finely-laminated 

 sandstone. The majority of them are evidently waterworn, but 

 some of them have the appearance of having received an artificial 

 finish, especially one circular stone, and another of globular shape, 

 with a knob on it, which he described minutely and exhibited to 

 the meeting. Wrought wood was said to have been found in the 

 same cutting, and one piece was exhibited ; but, owing to the 

 workmen having cut it in various places, the marks of original 

 workmanship, if any were on it when it was found, could not be 

 distinguished from the recent markings. 



The stones from the well are of similar material to those from 

 the cutting. Some of them are grooved and scratched, showing 

 signs of glacial action, and some of them when broken up have 

 impressions of leaves between the layers. 



The well had to be sunk to the rock before water was procured, 

 and the depth is 37^ feet. There was the ordinary unstratified 

 Boulder Clay, or Till, passed through to the depth of 30 feet,
