The hjemaphsein left upon incineration a trace of peroxide of 

 iron, and some carbonate of soda; the alcohol- extract left 

 chloride of sodium and carbonate of soda ; and the water-extract 

 left chloride of sodium, carbonate of soda, sulphate of soda, and 

 phosphate of lime. 



The blood discharged in hsematemesis is, according to Schon- 

 lein^s observations, either clear and very fluid, or black and 

 coagulated ; sometimes the two forms are mixed. The taste of 

 the blood is bitter if any bile is mixed with it, acid if the spleen 

 is affected. 



Ancell^ states that vomited blood is often coagulated, of a 

 dark brown or blackish colour (in consequence of the acids of 

 the stomach) ; in other cases it resembles coffee-grounds. 



In a girl, who brought up enormous quantities of blood, I 

 found that it occurred, for the most part, in rather large brownish 

 red coagula : the fluid had a faintly acid reaction, but on 

 touching a section of a clot with red litmus paper, a blue tint 

 was produced. The microscope revealed the presence of cor- 

 puscles in a state of good preservation. 



In haematuria the blood is mixed with urine. If the quan- 

 tity of the blood is very small, all the blood-corpuscles may be- 

 come dissolved, as I have frequently observed. The urine, how- 

 ever, coagulates on heating, and the colour disappears after 

 boiling, while discoloured flocculi are thrown down. The cor- 

 puscles are frequently preserved entire, and form a sediment, 

 on allowing the urine to stand for some time. In this case 

 they can be detected by the microscope.
