XXII. An Account of the Organs of Generation of the Mexican 

 ProteiiSy called by the rfatives AxolotL By Sir E. Home, Bart. 

 VPRS. 



The author of this paper considers thatCuvier has proved that 

 the Proteus of Germany, as well as that of Carolina, are actually 

 animals in a perfect state, and not larvae. The discovery that 

 the vertebraj of the Mexican Proteus were cupped in the" same 

 manner as those of the two other species, had already convinced 

 him that it also belonged to the same tribe, and was conse- 

 quently an animal in a perfect state. To place this question, 

 however, beyond all doubt, Sir Everard obtained from Mr. Bul- 

 lock several specimens, having the organs of generation in a 

 developed state, brought from a Lake three miles from the city 

 of Mexico. The temperature of this lake is never below 60°, 

 and its elevation above the sea is 8000 feet : in the month of 

 June, the Protei are so abundant in it as to form a principal part 

 of the food of the peasantry. Three plates of these animals, 

 with dissections of their generative organs, are given from draw- 

 ings by Mr. Bauer. The female organs in their developed state 

 are beautifully shown, and there is every probabihty, from the 

 appearance of the ova contained within them, that they pass out 

 singly. 



XXIII. An Account of Experiments on the Velocity of Sound, 

 made in Holland, By Dr. G. Moll, Professor of Natural Philo- 

 sophy in the University of Utrecht, and Dr. A. Van Beek : com- 

 municated by Capt. H. Kater, FRS. 



In our next number we shall give an abstract of these import- 

 ant and accurate experiments; together with remarks on the 

 questions involved in the subject of the velocity of sound, and on 

 some late investigations of them 



XXIV. A Catalogue of nearly all the principal fixed Stars 

 between the Zenith of Cape Town, Cape of Good Hope, and the 

 South Pole, reduced to the 1st of January, 1824. By the Rev. 

 Fearon Fallows, MA. FRS. 



The nature of this first contribution to science from the new 

 Observatory at Cape Town, renders it, of course, unsusceptible 

 of abbreviation. The same may be said of the concluding 

 paper in the volume ; viz. 



XXV. Remarks on the Parallax of a Lyrre, By J. Brinkley, 

 DD. FRS. Andrew's Professor of Astronomy in the University 

 of Dublin.
