Home’s zealous and earnest interposition, his labours would 
have been confined to that less interesting and useful branch of 
human knowledge. With the exception, perhaps, of Mr. Clift, 
whose accuracy and rigid adherence to nature and to truth can 
never be too highly estimated, Mr. Bauer has shewn himself, 
under the auspices of our author, the most correct and able 
anatomical draughtsman in Europe, while the dexterity and 
skill with which he uses the microscope, confer a peculiar cha- 
racter and unrivalled value upon many of his graphical con- 
tributions. The engravings annexed to this paper, were they 
the only produce of Mr. Bauer's pencil, would amply justify 
the above remarks ; they are not only executed with infinite 
taste and delicacy, but when minutely compared and examined, 
they carry with them entire conviction as to their accuracy, and 
conformity to nature, qualities which the works of Mr. Bauer’s 
microscopical predecessors very rarely possess. Sir Everard’s 
paper consists in a minute detail of the phenomena of the in- 
cubation of the egg, every statement that is advanced being 
verified by reference to the annexed drawings, so that any 
abstract, without such aid, would scarcely be intelligible. Itis a 
curious contribution, and fills a gap which has long existed 
in this department of physiology. 
8. Some Observations on Corrosive Sublimate. By John Davy, 
M.D., F.R.S. , 
The object of this communication is to rectify some errone- 
ous statements which have prevailed in chemical and pharma- 
ceutical writers, respecting the solubility and other chemical 
habitudes of corrosive sublimate. It is shown that light slowly 
decomposes the aqueous solution of corrosive sublimate, as 
also the liquor hydrargyri oxymuriatis of the Pharmacopeeia ; 
but that the solutions in alcohol and in ether, and those in 
water acidulated by muriatic acid, or containing a little muriate 
of ammonia, are not thus affected. That water at 57° dissolves 
about 5.4 per cent; alcohol at 60°, 50 per cent., and ether 
about 33 per cent of this substance. That corrosive sublimate, 
and the volatile and fixed oils, mutually decompose each other. 
That muriatic acid, sp. gr. 1.158, at 74°, dissolves twice its 
weight, forming a solution of a sp. gr. =2.412, which suddenly 
solidifies when cooled a little, but again liquefies in the warm 
hand. That it is insoluble in concentrated nitric and sulphuric 
acids, even at the temperature of 90°. That muriate of ammo- 
nia and corrosive sublimate unite, and form double salts, 
That a saturated solution of muriate of ammonia, at 60°, dis- 
solves its own weight of corrosive sublimate. That a saturated 
solution of common salt, composed of 20 grains of water and 
7 of salt, dissolve 32 grains of corrosive sublimate, at 60°.
