QUADRUPEDS. 275 



Rhinoceros. Figure 12, PI. XVII, is a molar tooth of the 

 rhinoceros, corresponding with that figured by Mr. Parkinson, III. 

 PI. XXI, Fig. 2. The masticating surface is above two inches long, and 

 nearly two broad. Perhaps No. 7, PI. XVII, may be a smaller grinder 

 of the same animal; to which also several of the large bones belong. 



Hippopotamus. We are not sure whether any of the teeth 

 which we have obtained belong to this animal. Some of the large leg 

 and thigh bones, that are very short in proportion to their thickness, 

 may fairly be assigned to it. The existence of its relics in the cavern, 

 we state on higher authority than our own, viz. on that of the Author 

 of the Organic Remains, of whose valuable researches we have so 

 often availed ourselves.* 



Horse. The grinders of the horse have been found in consider- 

 ble quantity ; and several of them are in a state so sound and com- 

 plete, that on receiving some of them, we at first suspected that a trick 

 had been played by some relic-monger, till we ascertained them to be 

 genuine. — No. 14, PI. XVII, is a bone analogous to one of the 



* Among those who explored the cavern, Mr. Gibson of Stratfoi-d, Essex, took an active 

 part; and that gentleman having shewn his large collection of bones and teeth to Mr Parkin- 

 son, the latter politely favoured us with his opinion of some of them. We are indebted also to 

 the Rev. Jos. Smyth, A. B., the Rev. Wm. Eastraead, and Mr. Harrison, Surgeon, all of 

 Kirkby Moorside, for many interesting specimens from the cavern, and much valuable in- 

 formation respecting it. 



Here we may lake occasion to observe, that all the Figures in the sixteen Lithographic 

 Plates, illustrating the Organic Remains of the district, were drawn from specimens examined 

 by the authors. Most of these are in their own possession ; and for the use of others they have 

 been principally indebted to Mr. Geo. Watson, and Mr. Henry Weatlierald, Whitby ; Thomas 

 Hinderwell, Esq., Scarborough; and Mr. Waters, Bridlington Quay. The stone used for the 

 Plates is that of the district, being partly from the Hildenley limestone, but chiefly from the blue 

 limestone connected with the oolite at Pickering. The Figures, if inferior in beauty to those in 

 some Geological Works, are on the whole superior in accuracy ; as might be expected from 

 this circumstance, that the whole process of drawing, engraving, printing, and colourings 

 has been done under the eye of Mr. Bird, and chiefly by his own hand.
