2. Spinal sedatives, chloral hyd. and bromides, belladonna, 

 etc. 



3. Nerve sedatives, bromides of pot. and ammon. 



4. Vascular sedatives, as aconite in small doses. 



5. Cardiac sedatives, as aconite, veratrum, etc. 



Tonics. — Are drugs which neither excite action like stimu- 

 lants, nor depress like sedatives, but produce a permanent though 

 scarcely perceptible excitement of all the vital functions. Their 

 effect being chiefly perceived in the increased tone or vigor of the 

 entire system. (Examples). 



Strych. for spinal cord. 



Iron for blood. 



Digitalis for heart.

They are drugs which so influence nutrition as to increase 

 the vital power. 



THE FOLLOWING CROUPS ARE MERELY SUBDIVISIONS OR LOCAL 

 APPLICATIONS OF THE THREE FOREGOING GRAND DIVISIONS : — 



Drugs acting on protoplasm, blood and low organism or dis- 

 ease germs and parasites are called antiseptics, disinfectants, deo- 

 dorizers, parasiticides and antiperiodics. 



Antizymotics. — Agents which arrest all fermentative proc- 

 esses, and includes antiseptics and disinfectants. 



Putrefaction — To Make Rotten. — Is the decomposition of 

 nitrogenous organic matter under the influence of micro-organ- 

 isms, and accompanied by the development of disagreeable odors, 

 due to the evolution of ammonia and hydrogen sulphide. 



Antiseptics. — Arrest putrefaction on or in the body, or arrest 

 septic decomposition by killing the bacilli which produce it or by 

 arresting their development, examples corros. sub. and carb. acid. 



Disinfectants. — Destroy disease germs and the noxious prop- 

 erties of fermentation and putrefaction (outside of the body), by 

 killing or arresting the development of those germs which pro- 

 duce disease, as lime, sulphur gas, etc. 



Deodorizers or Deodorants. — Destroy smell, either by absorp- 

 tion, as dry earth, charcoal, etc., or by acting upon them chemic- 

 ally, as chlorine and sulphurous acid gases, iron sulphate, etc. 



Parasiticides. — Kill the various animal and vegetable organ-
