tion given, except that*of''^ro.f. Sayi,^of Pisa, (Edinburgh 

 Phil. Journal, Vol. XII.) ^Ir consistQji of a duplicature of 

 mucous membrane hanging in loose folds, extremely soft and 

 flaccid to the feel, and held together by a very lax cellular 

 tissue ; the surface had rather a dark red color. On cut- 

 ting it through, there was no appearance of a cavity, neith- 

 er of glands nor muscular fibres. It descended into the 

 cavity of the mouth three and a half inches, and arose by a 

 broad base, of a triangular form, having its apex posteriorly, 

 and measuring two inches transversely in front ; it commen- 

 ced one and a half inches from the anterior extremity of 

 the soft palate and did not reach its posterior or free edge 

 by three and a half inches. Above it, and as if forming a 

 part of the soft palate, is a firm and highly vascular tissue. 

 Anterior to it there is, beneath the mucous membrane, a 

 great number of glands, of a very regular, flattened oval 

 form, of the size of large apple seeds, and situated close to- 

 gether, as they are often found about the lower extremity of 

 the oesophagus of birds. On each side of it, and occupying 

 about the seat of the tonsils in man, are numerous glands of 

 a rounded form and about the size of peas ; from the large 

 and open orifices of the ducts of many of these there project- 

 ed, sometimes one or two and sometimes several light colored 

 fibres, which looked like coarse hairs or bristles, about two 

 or three lines in length, and easily withdrawn, not seeming 

 to be attached within the cavity of the follicles ; what these 

 were was by no means apparent. Between this organ and 

 the posterior edge of the soft palate there were no glands to 

 be seen, except a few towards the sides; the upper surface 

 of the palate, however, within the posterior nares was cover- 

 ed with them, though they were not larger than pins' heads. 

 Prof. Savi, who made his observations upon the large col- 

 lection of dromedaries near Pisa, remarked, as naturalists 

 generally have, upon the rattling sound which the palatine 

 organ produces in the throat when the animal is excited, 

 especially during the rutting season, and that during the 

 act of copulation it is even protruded externally from the 

 mouth, in the form of a deep red, vascular, membranous bag
