XXXIII. ON THE STRUCTURE OF HAIRS AND OTHER CUTICULAR AP- 

 PENDAGES IN VARIOUS CLASSES OF ANIMALS. No. 2. 



By George Busk, Esq., Surgeon to the Hospital Ship, 

 Dreadnought, #c. 



THE hairs figured in Plate 2. accompanying the present number of 

 the Journal, are those belonging to animals in the following classes of 

 Mammalia : 



I. RODENTIA. 



Rabbit figs. 5, 7, 15, 24. 



Rat figs. 14, 18. 



Musquash (Mus. Zibeth. Gm.) figs. 13, 22, 23. 



Hare fig. 10. 



II. CARNIVORA. 



1. Digitigrada. 



a. Viverrine. 



Ermine (Putorius. Cuv.) figs. 1, 2, 12. 

 Stoat or Fitch (Putorius ? Cuv.) figs. 4, 6, 9. 

 Sable (Mustek. Zibell.) figs. 3, 21. 



b. Feline. 



Cat fig. 17, 20. 



Ocelot (F. Pardalis) fig. 11. 



Tiger (F. Tigris) fig. 16. 



c. Canine. 



Dog (Canis Fam.) fig. 19. 



2. Insectivora. 



Mole (Talpa) fig. 8. 



The hairs of the Rodents here figured, farther corroborate what was 

 advanced in the former notice on this subject (p. 33), namely, that in this 

 class the hairs are furnished in the interior, with distinct, regular, colour 

 cells, in which only, is the colouring matter of the hair deposited. In 

 fig. 15, the white hair of a rabbit, the cells will be observed to be quite 

 empty; and in fig. 24, which is taken from a hair partly black and 

 partly white, some of the cells are empty, while others are more or less 

 filled with black matter.
