(6) By the genito-ueinary passages. — This method of medication 

 is especially useful in treating local diseases of the genito-urinary 

 organs. It finds its chief application in the injection and cleansing 

 of the uterus and vagina. For this purpose a large syringe, or the 

 irrigator described above may be used. 



(7) Bt the blood. — Injections directly into veins are to be prac- 

 ticed by medical or veterinary practitioners only, as are probably 

 some other means of giving medicines — intratracheal injections, etc.
