have been downwards as well as upwards, thus increasing 

 indefinitely the already almost inconceivable vastness of the 

 time necessary for these processes. And yet, as I have 

 already stated, this is but the modern period, and in refer- 

 ence to the preceding eras of geology, may be said to be but 

 of yesterday. 



From the foregoing remarks we may conclude that there 

 was "a time when the Firth of Clyde was a sea several 

 miles wide at Glasgow, covering the site of the lower districts 

 of the city, and receiving the waters of the river not lower 

 than Bothwell Bridge." And we may imagine that at the 

 time when the beds of sand, which I have already referred to, 

 were being laid down in the hollow of Sauchiehall Street, the 

 waters of this noble estuary eddied around the various 

 eminences which mark the physical geography of Glasgow. 

 Garnet Hill would stand out conspicuously, a rounded island 

 of mud, separated by a narrow and not deep channel from 

 Blytheswood Hill. A broader and deeper current would 

 flow on the side towards the hill w^iere Port Dundas now 

 stands, finding its way into the main channel somewhat 

 farther westward, while to the south, the wide expanse of 

 water would sweep on towards the southern hills with per- 

 haps Camphill and Hillhead, and the other knolls on the 

 south side of the river, appearing as islets here and there. 

 The scene would wear more the aspect of a land-locked bay 

 or inland sea than of an estuary. 



V. On Species of Ehadinichthys from the Coal Measures. By 

 Kamsay H. Traquair, M.D., F.G.S. 



In a paper recently communicated to the Geological Society 

 of London,* I proposed to establish the new genus Ehadin- 

 ichthys for the Falceoniscus ornatissimus of Agassiz, and those 

 species which are allied to it in certain points of structure. 

 The fishes which may be included in this genus are of com- 

 paratively small size, the largest (B. ornatissimus) attaining a

 Pygopterus'^ {Qu. Journ. Geol. Soc. London, xxxiii., 1877, pp. 548-578).
