a sure indication of danger. ATbuminuria is sometimes in- 

 duced. 



Carbolic acid also leaves the "body by the saliva, which is 

 increased, and it stimulates the flow of sweat although it is 

 not found in it. 



Resorcin. (Not Officinal) A derivative of car- 

 bolic acid by various processes. 



Characters. "White tabular lustrous crystals, with a weak 

 odour like carbolic acid, and a sweetish, somewhat pungeut 

 taste. Solubility, 1 in 2 of water ; 1 in 20 of olive oil. 



Dose. 5 to 30 gr.~ every two hours, or single doses of 60 

 gr. at long intervals. 



ACTION AND USES. 



Externally. Resorcin is antiseptic and disinfectant, with- 

 out being irritant, in ordinary solutions (2 to 10 per cent.) It 

 has been used as a dressing for all kinds of sores and wounds. 



Internally. It passes rapidly through the system, and is 

 excreted unchanged in the urine by the end of one hour. It 

 causes diaphoresis, and reduces the temperature and pulse for 

 a time in conditions of fever ; but has no influence on the normal 

 body heat. Excessive doses cause trembling, singing in the 

 ears, deafness, and mental disturbance. It has been used as an 

 antipyretic in fevers of every kind, and is said to be specially 

 useful in ague ; but the drug is still on its trial.

 15 gr. 



ACTION AND USES. 



Chinolin is antiseptic and disinfectant externally. In-

 for the same class of cases.
