216 Notice of some Recent [March 



He analyzed a tumor from the kidney of a woman, and 

 obtained an albuminous liquid in which Cholestin was con- 

 tained. 



Wiggers found a concretion from the uterine portion of 

 a woman's placenta to contain fibrine, with some fat and 

 albumen 46*1645, phosphate of lime with traces of mag- 

 nesia 43-6709, carbonate of lime 3*1646, water 7*000.

Calculus from the Kidney. — This calculus was found in 

 the kidney of a male subject, which had been brought to a 

 dissecting room in Glasgow. The quantity procured was so 

 minute, that the tests which I could apply were more limited 

 than could have been wished in the case of this concretion, 

 which appears to have contained at least traces of xanthic 

 oxide. 



Before the blow-pipe it blackens, giving out an odour of 

 animal matter, and fuses into a white enamel, very soluble 

 in nitric acid. When evaporated to dryness the residue 

 has a fine orange colour, and when boiled with water, it 

 does not appear to be dissolved, but tinges it of a hyacinth 

 colour, which is converted into a lemon yellow by the 

 addition of a little nitric acid. Insoluble in caustic am- 

 monia. Not sensibly soluble in caustic potash, by which it 

 is precipitated from the nitric acid solution, the precipitate 

 not being re-dissolved by adding an excess of potash. 



Creatine, (Journal de Chem. Med. viii. 548.) — Chevreul 

 gives this name (from K^a<; flesh) to a crystalline substance, 

 which is obtained by heating with alcohol the extractive 

 residue which remains after the evaporation of the solution 

 of muscle. A substance remains then mixed with the ex- 

 tractive matter, from which it may be separated by crystal- 

 lization. It exists in minute quantity in muscle. It is 

 colourless, crystallizes like common salt, in cubes, has no 

 taste, is neutral, insoluble in alcohol, very soluble in water 

 and nitric acid. 



BOTANY. 



Botany of Wermland and Dalsland, by C. G. Myrin. — 

 Dalsland is a small province of Sweden, on the west of 

 Lake Wener, presenting an undulating surface, and belong- 

 ing to the primitive formations. Wermland lies rather 

 north of Lake Wener, and extends as far north as 61°,
