was one of the group that contained the roptilo referred ta 

 So that both speciinena are of unugual interest. The rcptilo 

 was described by Professor Owen and named Dendrerj^eton 

 (tree reptile) aradianfnm }. In the Museum we have a 

 restoration of it bj Waterhinise Hawkins, — the size of it is 

 about 2 feet 9 inches. The hirgest amphibian of its form that 

 we now have in Nova Scotia is the violet Salamander, wlloso 

 Jength is 6 to 7 inches. The reptile seems to have been a 

 lizard. 



If you look into Lyell's Elements of Geology, Dawson's 

 Acadian Geology and Dana's Manual and Text Book of 

 Geology you will see erect columns, which represent trees in 

 position, the greater part of them are Sitji/lana ; many of 

 them may be sepulchres of reptiles. At the time when the 

 creatures found their way into tiiem, they seem to have been 

 hollow. 



Our Rhizodus tooth is conical, recirrveJ, stout, its length 

 is 1 1 inch, its root is | inch wide. From this it has its 

 name— r/ii2a a root and odiis a tooth. The tooth of our 

 Ilorton Bluff ganoid is pigmean compared with it. Its pro- 

 portions approximate those of the great Holopfi/chius of the 

 Scotch Old Eed Sandstone and Carboniferous formations. 



Prof. Marsh of Yale College found two large vertebrae ai 

 the Joggins, and published a description of them in 1862. 

 In this he referred them to the enaliosaurs or sea-lizards, and 

 nimed their original owner Eo-saurus, — Dawn-lizard — aca 

 dianua. Thus Nova Scotia at this early period had the pre- 

 cursor of those great sea monsters which culminated at a later 

 period, the Jurassic. 



11, Before my first visit to the Joggins I had collected 

 specimens on the north side of the Pictou coal field. 

 At Deacon McKay's mine. New Glasgow, I found singular 

 teeth in clay slate that had fallen from the roof of the 

 mine. With the teeth were small spines and ganoid scales of 

 various forms and sizes, — some of them large and beautiful. At 

 Patrick's mine on the south-west side of the same coal field I 

 found similar teeth, subsequently. From a mine next McKay's
