Phenol  Tablets. — Under  this  name  a  firm  in  Germany  is  now 
marketing  a  compressed  tablet  containing  the  oxalic  acid  ester  of 
phenol.  This  substance  contains  32  per  cent,  of  oxalic  acid  and 
68  per  cent,  of  phenol,  has  a  melting-point  of  from  1220  to  1240  C, 
is  non-hygroscopic,  practically  non-caustic  and,  on  solution,  disso- 
ciates into  its  constituents.    (Pharm.  Centh.,  1908,  p.  797.) 
Spivosal  is  defined  by  the  Council  on  Pharmacy  and  Chemistry  of 
the  American  Medical  Association  as  the  monoglycol  ester  of  sali- 
cylic acid.  It  occurs  as  an  almost  odorless  and  colorless  oily  fluid, 
easily  soluble  in  alcohol,  ether,  chloroform  and  benzol  and  soluble 
in  about  no  parts  of  water  and  in  8  parts  of  olive  oil.  It  is  recom- 
mended to  be  used  externally  in  rheumatic  affections.  (Jour.  Am. 
M.  Assoc.,  Oct.  31,  1908,  p.  1513.) 
Tannyl. — This  occurs  as  a  yellowish-gray,  odorless  and  practically 
tasteless  powder  containing  about  50  per  cent,  of  tannin  in  combina- 
tion with  oxychlor  casein.  It  is  only  very  slightly  soluble  in  water 
or  in  alcohol,  but  is  readily  soluble  in  alkaline  solutions.  It  has 
been  recommended  as  an  internal  astringent.
