THE BLOOD.

the blood. The lancet in frequent bleedings, putrid water, 

 the poison of the viper, fumes of charcoal, bicarb, sodae, 

 nitre, digitalis, with many others, have this agency. 



But there are fortunately other agents which have a ten- 

 dency to promote coagulation, and to arrest the disposition 

 to its destruction. Among these stands at the head of the 

 list water, then sulphate of magnesia, nitrate of silver, &c. 



This property of ihe blood being of such great import- 

 ance in the preservation of health and life, we deem it not 

 out of place here to give a brief summary, from the ex- 

 periments of M. Magendie, of all those agents which he 

 found to aid or promote this principle of coagulation, and 

 all those which destroyed it. 



Under the first head of agents promoting coagulation, 

 are arranged: 



Water, 



Sugared Water, 



Hydrochlorate Sodae, 



Potassas, 



Ammonia, 



Baryta, 



Serum of Ascites, 



Boracic Acid, 



Borax, 



Nitrate of Silver, 



Hydrosulphates of Potassa 

 and Ammonia 



Seltzer Water, 

 Vichy Water, 

 Seidlitz Water, 

 loduret of Potass, 

 Tart. Ant. and Potass, 

 Sulphat. Magnesia, 

 Alcohol, 

 Cyanuret of Gold, 



" Mercury, 



Hydrochlorate and Mannite 

 of Morphia. 



Second doss, or agents which destroy coagulation. 



Sulphuric, 



Hydrochloric, 



Nitric, 



Tartaric, 



Oxalic, 



Citric, 



Acetic, 



Tannic, 



Hydrocyanic, 



Lactic, 



Soda, 



Acids. 



Potassa, 



Lime, 



Ammonia, 



Sodaa, 



Potassas, 



Ammoniae, 



PotassaB, 



Lime, 



Strychniaa, ) 



Sulphate Morphia, 



Nicotine. 



Carbonates. 



Nitrates. 



The gases and wines also modify this property.
