 cheapness at which they may be purchased.

CAPSTJIAE — CAPSULES 



Capsules are ovoid or cylindrical shells of gelatin used for the 

 administration of various forms of medicines, powders, masses or 

 liquids. They are termed hard or soft according to the amount of 

 glycerin contained in the mass from which they are made. Hard 

 capsules consist of a shell and cap or cover. They are a fairly 

 popular means of administering medicines in veterinary practice. 

 They may be filled with powders by placing the powder upon a 

 clean piece of paper and gently pressing the shell into the mixture 

 when it will gradually fill. In order to get the exact amount in 

 each capsule they should be weighed. This may be easily done by 

 having the weight plus an empty capsule on one scale pan and 

 throwing the filled capsule upon the other pan. If not sufficiently 

 filled a little more pressure will bring the desired amount and if it 

 is already over-filled a slight tapping upon the inverted capsule 

 will throw out the excess. In case of very large capsules the powder 

 may be poured directly into the capsule and cap. Liquids may 

 also be poured into the shell of the larger capsules or dropped into 

 the smaller ones by means of a pipette or burette. It is needless 

 to say that liquids which dissolve gelatin must not be placed in 

 capsules unless they are to be given at once.
