the  work  received,  the  formulas  for  such  galenical  preparations  as 
have  now  received  official  recognition  in  Great  Britain,  with  such 
details  of  manipulation  appearing  desirable  or  necessary.  It  should 
be  remembered  that  the  British  fluidounce  differs  from  that  of  the

ounce  of  water.
