508. Strength of Drvgs. — The most suitable 

 form in which to keep most drugs is that of the 

 fluid extract or in tablets. 



For hypodermic use they should be kept in 

 tablets ; then there is no risk of giving the wrong 

 dose, as there will be no weighing out to be done. 



The dose of the fluid extract is the same as 

 that of the powder, if there is one. 



The dose of the tincture, which is an alcoholic 

 solution of the fluid extract, is eight times that 

 of the fluid extract (F.E.).
