antiseptic,  aromatic  oils  that  play  an  important  part  in  the  published 
formula,  were  in  reality  only  added  as  flavoring  ingredients. 
From  the  information  thus  obtained,  the  following  formula  was 
adopted. 
Kaolin  1,000 
Glycerin  1,000 
Boracicacid  •   100 
Oil  of  peppermint   1 
Oil  of  wintergreen   1 
Oil  of  eucalyptus   2 
Pass  the  kaolin  through  a  No.  60  sieve  to  free  it  from  sticks  and 
coarse  particles  and  heat  to  ioo°  C.  for  an  hour  or  more  to  sterilize ; 
add  the  glycerin  and  continue  the  heat  for  thirty  or  forty  minutes, 
stirring  the  mass  occasionally  with  a  spatula,  until  a  smooth 
creamy  mass  is  obtained ;  remove  the  heat  and,  when  nearly  cool,  add 
the  boracic  acid  and  flavoring  oils;  mix  thoroughly,  and  preserve  in 
tin  or  glass  boxes  that  are  fairly  tight,  so  as  to  prevent  the  absorption 
of  moisture  from  the  atmosphere.  The  resulting  product  will 
differ  slightly  in  color  owing  to  a  slight  difference  in  the  constitu- 
ents of  the  kaolin,  the  kaolin  sold  in  Philadelphia  not  containing 
any  iron,  while  a  lot  that  was  obtained  through  a  New  York  house 
did  contain  a  trace  of  iron.  This,  however,  does  not  affect  the  effi- 
ciency of  the  product  in  any  way. 
SOME  NOTES  ON  CHONDRUS.1 
By  Henry  Kraemer. 
In  this  paper  I  desire  to  treat  of  some  of  the  morphological  char- 
acters of  chondrus,  its  collection,  as  carried  out  on  the  Massachu- 
setts coast,  and  some  reasons  for  the  modification  of  the  definition  of 
the  US. P.  concerning  this  drug.  Chondrus  belongs  to  what  we  or- 
dinarily consider  to  be  a  low  order  of  plants,  viz. :  one  of  the  algae — 
a  subdivision  of  the  cryptogams.  The  number  of  algae,  like  that  of 
fungi,  is  continually  increasing  either  because  more  formsare  being  ob- 
served or  because  new  forms  are  being  made  with  the  progress  of  time. 
The  algae  are  divided  according  to  whether  they  live  in  fresh 
water  or  salt  water,  and  according  to  the  color  they  possess.  By 
the  latter  division  we  have  green  algae,  blue-green  algae,  brown  algae 
and  red  algae.    In  only  one  of  these  divisions  do  we  have  algae  in
