of mercury, it will yield a copious milky floccuient precipitate 

 resembling white of egg; and in some cases not in all 

 the albumen contained in it will coagulate on exposure of

This disease is amongst the most frequent ones affecting

 and traumatic. 



The traumatic haematuria occurs as the result of strains
