Grass. I, Sky) A Tae 
vaft creature is found in the Norwegian feas, we 
think it not improbable but that it may have ap- 
peared on the Scottifh coafts,; but having no better 
authority for it, than what is above-mentioned, we 
dare not give ita place in a Brita Zoology. The 
teeth of that animal are as white and hard as ivory ; 
but whether the ercodyrma bdna, ivory bits, which 
Strabo * mentions among the articles of the Britifh 
commerce, were made of them, or the tooth of 
the Narbwal, or of fome of the toothed whales, 
is not at this time eafy to be determined. But we 
may here remark that Solimus, in his account of 
Britain, informs us that the fine gentlemen of our 
ifland adorned the hilts of their fwords with the 
teeth of fea beafts, which were as white as ivory 
itfelf +.
