palceotherium, were both incisors and canine teeth, but it 

 had one molar tooth less, and no space between the first 

 molar and the canine tooth. The other characters leave no 

 doubt that this animal approached to the palceotherium. 



The anoplotherium was traced from several grinding 

 teeth having been found which appeared to belong to an 

 animal which had no canine teeth : it indeed appeared, that 

 in the lower jaw of this animal there had been fourteen 

 grinding and six incisive teeth, without any canine tooth or 

 intervening space. The teeth of the upper jaw appear to 

 correspond with those of the lower jaw; there not being 

 any canine tooth, or any space between the incisors and the 

 grinders. 



Besides other particularities of structure, it was found 

 that, in this animal, the hind leg had two perfect toes arti- 

 culated with two metatarsal bones, which remained distinct 

 and separate through life : a structure unknown among 

 living animals. 



The most common species of this animal, An. commune, 

 appears to have rather exceeded, in its size, the wild boar. 

 The foot of A. medium was of a size which would have 

 agreed with that of a sheep of a middling size. A. minus, 

 reckoning from the size of its foot, was about the size of 

 the hare. 



After the examinations of various specimens of separate 

 bones, during eight years, two skeletons were fortunately 

 obtained which were nearly complete. The first was of an 

 animal of nearly the size of a small horse. The ribs were 

 found to be twelve, and the tail was ascertained to be of 

 vast magnitude, being formed of, at least, twenty-two 

 vertebrae ; and equalling, if not surpassing, the body in 

 length : there were reasons also for supposing that the thick- 

 ness of the tail must have been as enormous as its length. 



Half the jaw of a small carnivorous animal of the genus 

 canis, of an unknown species, was also found in these
