298 Mr. T. Andrews's Chemical Researches 



In order to obtain the remainder of the saline matter frotn 

 the incinerated mass, it was boiled in acidulated water, "050 gr. 

 of saline matter was obtained, of which '027 gr. dissolved in 

 water. The remainder was dissolved in nitric acid and pre- 

 cipitated by ammonia of a slightly red colour, then redissolved 

 in nitric acid and precipitated by oxalate of ammonia ; but I 

 could not detect any magnesia in it, probably from the minute 

 scale on which the experiment was performed. 

 The serum therefore contained, 



Water 874.-59 



Albumen 116'40 



Chlorides of sodium and potassium^ 



with uncombined alkali J 



Carbonate and phosphate of soda . . 1'36 



Sulphate of potash '25 



Phosphate of lime "71

 Crassamentum. — 23*49 grammes were dried in the same 

 manner as the albumen ; they lost 16'472 gr. of water. This 

 water arose from the serum in the crassamentum, and must 

 have been united, by its analysis, to 2*360 gr. of albumen and 

 salts. Hence the crassamentum consisted of 18*832 serum, 

 and 4*658 red globules and fibrin. 



58*58 grammes of the same crassamentum were washed to 

 separate the fibi'in, but the process was very tedious ; and 

 after persevering for above a week, I did not succeed in ren- 

 dering the fibrin perfectly colourless. It was dried at the 

 same temperature as the albumen and crassamentum. It 

 weighed '52 gr. and was of a dirty green colour. 



From these experiments the composition of the blood was. 



Water 78*43 



Albumen and salts . . . 10*00 



Red globules 11*06 



Fibrin *51

 Specimen 2. Cholera Hospital, Ballymacarrett. — This spe- 

 cimen of blood was taken from a male patient (a;t. 50), who 

 had been seized with cholera the same morning, and died 

 early on the following day. From the commencement of the 

 attack he had passed involuntary stools, and vomited co- 

 piously. The pulse was perceptible before he was bled, but 

 afterwards became very faint and irregular. The blood 

 flowed with difficulty, and was of a vei'y dark colour and 

 viscid consistence. It coagulated perfectly, the serum was
