96 Historical Sketch of Improvements in [Aug. 



Animal matter 35 



Phosphate of hme 61 



Carbonate of lime with traces of phosphate 

 and carbonate of magnesia 4 



Too 



So that it contained more phosphate of lime and less carbonate 

 of lime than bone. — (Ibid. p. 233.) 



9. Ptyalism. — There is a cmious case of spontaneous ptya- 

 lism with diminished secretion of urine related by Dr. Prout 

 (Annals of Philosophy, xiv. 474). The saliva was said to have a 

 urinous taste : 1000 grs. of it, when evaporated to dryness, left 

 8*65 grs. of residuum, which consisted of 



Animal matter peculiar to saliva 3*33 



Ditto soluble in alcohol, and similar to those found 



in blood 1-06 



Sulphuric acid 0-90 



Muriatic acid 0*75 



Phosphoric acid 0*06 



Alkali, partly soda, partly potash 2*55

The specific gravity of the urine of this person was 1*0131. 

 It was amber coloured, and contained more acid an\i less urea 

 than usual. Diuretics increased the flow of urine, and diminished 

 that of the saliva. 



10. Urine of the Sow. — M. Lassaigne subjected the urine of 

 this animal to chemical analysis, and found in it the following 

 substances : 



Urea, 



Muriate of ammonia, 



Muriate of potash, 



Muriate of soda, 



Sulphate of potash. 



Sulphate of soda, 



Trace of sulphate and carbonate of lime. 



(Annals of Philosophy , xiv. 146.) 



1 1 . Urinary Calculus. — I subjected to analysis a fragment of 

 a calculus taken after death from the bladder of a person who 

 had been very much afflicted with gout. I found it composed of 



Uric acid, 

 Phosphate of lime, 

 Lime. 



Probably the lime was in combination with the uric acid 

 (Ibid. xiv. 468.)
