CIATTTS AND riUMIES.

I received from a miner another kind of a tooth. Of the first 

 I collected about 30 of various sizes. Tliewe are shark's teeth — ' 

 hijhodont. Tlu»y are called />//>/w/«i* — (d«mble tooth). Each 

 tooth is double. One single is upri<^ht, the otlicr curv^is bn';k- 

 ward ; a short cusp is between ; the root is largo. The teelb 

 are lancelate and crenulated ; llio largest trmth is formidable. 

 When I showed it to Professor l^liiliips at the London Exhibi- 

 tion of 18G2, he was astonished at its size and remarked that 

 it was much larger than the tooth of the British Diplodtta. 

 Our sharks of the Coal Period must have been formidable. 

 The ganoids, whose scales accMiipany the teeth, when once 

 <;aught by the Diplodm, waxq doomed. The odd tooth is about 

 I of. an inch in leiiglh ; it is conical, recurved and striated. 



In this field we have also an amphibian, a frog whose name 

 18 Buphctes planiceps. This was found by Sir J. William 

 Dawson, and described m Aca'fian Geology. This frog was a 

 giant when compared with the existing race of Nova Scotia 

 (frogs ; it was even much larger than the fiogs of the West 

 Indies. The specimens of those in our Provirniial Museum are 

 •certainly not pigmies, as they astonish visitors by their dimen- 

 sions. The Bajjheteti, too, has teeth wliich ccfuld hold on to a 

 palaeoniscus, although clad in ganoid coat of mail, tdr it in 

 (pieces and nmke a meal of it. At the London Exiiibition oi 

 1862 there was a live frog exhibited in a block of English coal, 

 and said io have been found in it. It was the subject of dis- 

 -cussion in the newspapers. It died during the controversy. 

 Visitors seeing our 30 feet Pictou coal column^ expected to see 

 the wonderful frog in it. If the Baphetes had been alive, and 

 ■exhibited in our coal column it would have astonished and con- 

 vinced t^e most incredulous " without centrov-erey " as trae and 

 jiot false. 



12. We would yet look at a few individuals whicli we 

 'have passed in our previous examinations. 



There is -the foot-print of a large Sauropus. This deep 

 ampression was found by J. M. Jones, "F. L. S., in the Carbonifer- 

 ous formation of Parrsboro*. Then a plaster cast in the Webster 

 .colleclion of a row of ioot-jprints found by Mr. Harding at
