9. Physostigmina has been found useful in promoting 

 the action of the bowels in cases of impaction, consti- 

 pation, and arresting indigestion, colic, &c. Dose, 20 

 to 60 drops. 



10. Quina is valuable in the extreme prostration of 

 influenza, parturition fever, septiccemia, &c. Inject 

 direct into the substance of a muscle. Dose, 20 to 60 

 drops. 



n. Strychnia, valuable for overcoming the nervi- 

 muscular weakness of strangles, influenza, lead poison- 

 ing, and spinal meningitis. Used with conia for tetanus, 

 with phosphorus for paralysis from injury, and the 

 early stages of roaring. Dose, h to 2 drams. 



Subcutaneous injections are administered by means of 

 a suitable syringe, armed with a hollow needle. The 

 latter is caused to penetrate a fold of the skin, &c, by 

 which the fluid remedy is passed within the cellular tissue 

 as the piston is forced down the glass tube. It thus 

 enters the circulation at once, and, being unaffected by 

 secretions, as when given by the mouth, also acts more 

 powerfully. 



TONICS. 



Tonics are those medicines which promote strength 

 and vigour — tone — of the constitution. They are always 

 resorted to in recovery from disease, but require care in 

 their prescription, as too early administration has been 

 known to cause fatal relapse.
