times in small, at others in very diminutive reddish brown and 

 brownish red crystals, specifically different from the basaltic, is 

 exclusively peculiar to this stone. 



III. New Species of Honey. 



In the kingdom of Imerethi, which constitutes a part of Georgia, 

 and lies at the east end of the Black Sea, at present subject to 

 Kussia, there is found a kind of wild honey, which is called by the 

 inhabitants stone-honey, because it is quite solid, brittle, and not 

 viscous. It has a pleasant and aromatic flavour, and is found in the 

 clefts of the rocks. Honey and wax form one mass, and are as 

 hard as sugar-candy. The cakes are commonly white, but turn ' 

 yellow with age, and will keep for a long time. The lmcrethians 

 carry it with them in their pockets. 



IV. Supposed Urinary Calculi. 



Some weeks ago I received from a surgical friend a paper con- 

 taining some specimens of stones, which, he informed me by 

 letter, had been passed by a boy of about ten years of age. On 

 opening the packet, I was very much surprised at the appearance of 

 these calculi. They were about twenty in number, the largest 

 about the size of a millet seed, and the smallest not larger than 

 grains of sand ; the shape was irregular ; some of them were 

 rounded, some had sharp edges ; they were mostly all transparent, 

 had a vitreous fracture, could not he scratched by a knife, and 

 readily melted with potash into a glass. In short, they were frag- 

 ments of quartz stones, which the boy had picked up, and which 

 he pretended to have passed, merely to deceive his parents, for 

 some purpose or other, which may easily be conceived. 



V. Substance extracted from the Vagina of an old Woman, 



From the same gentleman I received a specimen of a substance 

 which had been extracted from the vagina of an old woman. It is 

 of a yellowish white colour, smooth upon the outer surface, has the 

 hardness of bone, and easily breaks. When heated it gives out the 

 smell of burning feathers, and becomes black ; but if it be kept for 

 some time red-hot, it becomes quite white, and has the aspect of 

 burnt bone. It dissolves slowly, and without effervescence in 

 muriatic acid, from which it may be again precipitated by caustic 

 ammonia. These properties leave no doubt that it consists of 

 phosphate of lime, cemented together by an animal substance, 

 which is probably of the nature of mucus. When a portion of this 

 matter is kept for some days in a weak acid, almost the whole dis- 

 solves, and the undissolved portion is in a state of white flocks. 



VI. Prince Rupert's Drops. 



Dr. Brewster has discovered the existence of three cleavages in 

 the .glass tears, well known by the name of Prince Rupert's drops,
