CLASSIFICATION OF MEDICINES. 21 



The second general division, comprising Local Remedies, includes 

 the following orders : 



I. Dia'phoretics, or such as act specifically on the skin, producing 

 perspiration. 



II. Diuretics, or such as act upon the kidneys, increasing the 

 secretion of urine. 



III. Emetics, or such as produce vomiting. 



IV. Cathartics, or such as produce purging. 



V. Expectorants, or such as produce a local impression on the 

 lungs, increasing expectoration. 



VI. Er/imeno.gogues, or such as stimulate the uterine secretion, 

 promoting menstruation. 



VII. Sialogogiies, or such as stimulate the salivary glands. 



VIII. Errhines, or medicines which produce an increased dis- 

 charge of mucus from the nose. 



IX. Ecbolics, or medicines which produce contraction of the uterus, 

 so as to expel its contents. 



X- Epispastics, or such, as when applied to the surface, produce 

 vesication, or blistering. 



XI. Kuhefacients, or such as occasion redness and inflammation 

 of the surface. 



XII. Escharotics, or caustics, — which destroy the life of the part 

 to which they are applied. 



XIII. Emollients, or substances which soften and relax the skin, 



XIV. Demulce7its, — which act by protecting the surfaces, to which 

 they are applied, from irritation. 



XV. Diluents, or such as act by diluting the fluids of the body. 

 Besides the foregoing, the Local Medicines may also include 



ayitacids, or such as neutralize acid ; and anthelmintics, or such as 

 destroy and expel worms from the bowels. 



There yet remain three very important medicines to dispose of, 

 viz. mercury, iodine, and arsenic, — which it is found extremely 

 difficult to arrange under any of the preceding classes, on account 

 of the peculiarity of their modus operandi. Perhaps it will be best 

 to adopt the plan of some authors, and treat of them as a distinct class. 



The following table will present a synopsis of the foregoing 

 arrangement :
