liquors, cithi 

 their in qualities. 



Some infufions are made in common water, others in wine, 

 vinegar, milk, fpirit of wine, &c. Boiling water is fome- 

 times efTufed upon any fiihllancc,' and allowed to ftand upon 

 it for fomc time. Water is alfo occafionally effufed cold 

 in the fame manner ; and in this cafe the fpecilic form of 

 cold infufion is ufed. 



The fame operation is applicable to thofe fubftances 

 which contain any parts volatile in the heat of 212 , to the 

 reparation of more readily foluble conllituent parts from 

 thofe which are lefs fo, and to the preparation of flighter im- 

 pregnations than boiling for a length of time produces. The 

 boiling temperature of the water is fo foon loft in this mode 

 of application, that even with the nioft delicate fubftances 

 it does no injury, and it affifts in loofening the texture of the 

 vegetable, and efTei^in-j the folution much fooner than cold 

 vater alone does. InUifions are ufually matters of extem- 

 poraneous prefcription, and cannot generally be kept ready 

 prepared in the (liops without fpoiling. Their number has 

 been extended to moft of the articles in common ufe, and
