With respect to the Kerkadan [rhinoceros] chewing the cud, it is to be observed, that all the ruminating animals, except the camel, lama and musk deer, want the canine tooth altogether, and have no incisor teeth in the upper jaw; and although the system of dentition of the rhinoceros is different in different species, as far as regards the incicors, none of the genus have any canine teeth, and the R. Africanus also wants the incisors in both jaws. No inference, therefore, as to the Kerkadan's chewing the cud or not, can safely be drawn from its teeth, unless the form and structure of its grinders have been carefully and minutely observed.
