3. Blood of a patient labouring under Hcematuria. The re- 

 markable circumstance in the blood in this disease is the total 

 absence of colouring matter, as may be seen by the action of acids 

 on healthy blood, and the blood in a case of ha3maturia.

4. Blood in Scurvy. According to Fourcroy, blood drawn 

 from the gums of a person labouring under scurvy contains no 

 fibrin, does not coagulate, and becomes black on cooling. Ac- 

 cording to Deyeux and Parmentier, the blood of persons ill of 

 scurvy has a peculiar smell. The crassamentum from the blood 

 of three different scurvy patients was as firm, and contained as 

 much fibrin, as that of healthy blood. But the serum was diffi- 

 cultly coagulable by heat. One of the three crassamenta was 

 covered with the buffy coat. These facts are of little value, hav- 

 ing been determined at a time (1793) when the chemical inves- 

 tigation of animal substances had made too little progress to ex- 

 pect accurate experimenting. 



5. Blood in Diabetes. The opinion advanced by Dr Rollo, 

 that the blood in diabetes contains sugar, has not been verified by 

 future experimenters. Since neither Nicolas and Gueudville;
