Art. L— DISSECTIOxN OF TWO ADULT DROMEDARIES; A 

 MALE AND A FEMALE. By J. B. S. Jackson, M. D. 



The animals which are the subjects of this paper, died in 

 this city within a day or two of each other, having been 

 well, so far as was known, till within a few days before 

 death. They were about six years old, and weighed, by 

 estimate of their keepers, about 850 lbs. each. Most of the 

 organs were carefully examined, but some, though not over- 

 looked, were not particularly noted, and have therefore not 

 been recorded. 



The Hump on the back of the female consisted principal-

 and a half thick. Masses of fat, of a very regular and oval 

 form, were found in the soles of the feet, apparently intend- 

 ed to give elasticity to the step. 



Tongue of the male, sixteen inches long and two and one 

 half wide at the tip. Anteriorly thin, and covered by a 

 rough cuticle. Thickened portion, posteriorly, seven inches 

 long and two wide ; on each side of it a row of five or six 

 glands, from two to seven lines in diameter and remarkably 

 developed. 



The Soft Palate of the female was seven inches in length. 



To its under surface was attached that remarkable organ, 



which has been often described by naturalists, but of which, 



so far as I am aware, there has been no anatomical descrip-
