nuda, glabra, et depili contectum, in aquis perpetuo degens, nee 

 unquani sponte in siccum exiens." To Linnaeus belongs the 

 credit of disuniting for ever the whales from the proper fish, 

 and of establishing the connexion which naturally exists between 

 iiiem and the other mammalious beasts : on this subject he 

 ^iriost justly writes, " Hos a piscibus divulsos jussi mammalibus 

 associari ob cor biloculare calidum, pulmones respirantes, pal- 

 pebras mobiles, aures cavas, penem intrantem foeminana 

 mammis lactantem, idque ex lege naturae jure meritoque." 

 But the Linnaean dental system of subordinate arrangement 



*jdkused him still to keep them widely separated from the Du- 

 gongs, the Walruses, and Seals, their natural allies ; and which 

 are surely the ascending grades by which the pisciform mam- 

 malia become connected with the truly four-footed beasts. 

 Save Pennant, whose term Quadrupeda of course excluded 

 whales, all modern zoologists of note since Willughby and Ray, 

 have maintained the Linnaean doctrine, and classed the cetacea 

 with the other mammalious beasts, yet none have ventured 

 sufficiently to insist on their close affinity with the Seal and 

 Morse, although the Dugong, which forms the connecting link, 

 has been by some allied with the Cetacea, and by some with 

 the Trichecus. The old Celtic nomenclature would seem, in 

 part, to adumbrate this natural connexion between the wal-rus, 

 liox-whal, ivhale, and others ; and Blumenbach partly favoured 

 such an association, by subdividing his digitate and palmate 

 beasts into three sections each, viz., Glires, Ferae, Bruta; and 

 placing the latter next his ninth order, containing the dolphins, 

 the narwhal and the whales : but the distribution was marred 



^'oy associating the ornithorhynchus and the beaver, with the 

 ■walrus and the seal ; and this much more closely than either of 

 these latter with the dolphin and their natural allies 5 these 



''t'eing in' a different order, while those are in the same. Illiger 

 ialso placed his fin-footed beasts, the seals and morses, next to 

 iiis swimming beasts, i. e., the dugong, porpoise, whale, &c., 

 Ill like manlier as Lamarck and Carus have made their orders 

 Cetaicea and Amphibia contiguous; in which schemes, 

 although imperfect, and the term amphibia exceptionable, (it 

 having previously and more appropriately been apphed by those 

 %vriters, as well as by most other zoologists, to a quite different
