Wurzer analysed a concretion formed in one of the tonsils : 

 externally it was of a grayish white colour, marked with rose- 

 red spots, and verrucose ; internally it presented no appearance 

 of lamellae, although it contained an oval nucleus. It consisted 

 of phosphate of lime 63-8, carbonate of lime 16-7, animal 

 matter 13-3, ptyalin, with chlorides of sodium and potassium, 

 7*1, iron and traces of manganese, 0-1. Daniel has described a 

 hard and dense tumour, containing, however, traces of fibrous 

 tissue, that occurred in the anterior wall of the uterus of a 

 single woman aged 72 years. It contained 35^ of animal matter 

 and water, 56g of phosphates of lime and magnesia, 5 of car- 

 bonate of lime, and 4 of chloride of sodium and other salts. An 

 earthy deposit in the uterus, analysed by Wiggers, contained 

 46-8 of earthy phosphates and carbonates, and 46* Ig of fibrin, 

 with a little fat. Poggiale has examined the muscular tissue of a 

 man in whom ossification of the muscles had proceeded to such 

 a length as almost entirely to prevent any voluntary motion. 

 A portion of the ossified gastrocnemius contained 58 of organic 

 matter, 32'09 of phosphate of lime, 1'25 of phosphate of mag- 

 nesia, and 8*66^ of carbonate of lime. 



Concretions in the brain are very rare. I obtained a con- 

 cretion of this nature that had formed in the cerebellum; 

 it was about the size of a nut, of an irregular angular form, 

 very solid, and both internally and externally resembled a por- 

 tion of bone. The whole concretion was enveloped in a fine 

 coriaceous capsule ; it consisted principally of phosphate and 

 carbonate of lime, with a little cholesterin. A similar con- 

 cretion analysed by John consisted of 75 parts of the phos- 

 phates of lime and magnesia, and 25 of animal matter; another, 

 examined by Morin, was composed of cholesterin, coagulated 

 albumen, and earthy phosphates. In a concretion taken from 

 the brain of a horse Lassaigne found 58 parts of cholesterin, 

 39-5 of coagulated albumen and cellular matter, and 2'5 of 

 earthy phosphates.
