of  those  which  have  been  held  in  locations  which  are  more  access- 
ible, was  both  interesting  and  profitable  to  all  who  were  present. 
The  fair  weather  which  prevailed  contrasted  strongly  with  the  rainy 
period  which  had  marked  the  week  in  1905,  when  the  Association 
met  at  Bedford  Springs  before,  and  the  Entertainment  Committee 
outdid  themselves  in  their  efforts  to  provide  novel  and  pleasing 
features  for  the  enjoyment  of  the  members  and  their  ladies.

Notes  on  Glycerin  Suppositories. 
H.  C.  Blair. 
The  author  states  that  where  there  is  comparatively  small  demand 
for  glycerin  suppositories  they  can  be  made  extemporaneously  by 
the  U.  S.  P.  formula  in  a  satisfactory  manner,  but  that  for  large  stock 
quantities  the  best  results  are  obtained  by  adding  to  heated  glycerin 
3  per  cent,  of  soap  previously  made  from  stearin  and  sodium  car- 
bonate. This  soap  should  be  as  nearly  neutral  as  possible,  and 
dried  and  powdered.  The  advantages  over  the  official  preparation 
are  a  lower  melting  point,  greater  solubility,  firmer  consistence,  and 
as  there  is  less  water  in  them  they  are  much  more  hygroscopic.  If 
kept  in  well  stoppered  vials  and  in  a  moderately  cool  temperature, 
they  will  remain  in  a  perfect  condition  almost  permanently. 
Is  it  Profitable  for  the  Pharmacist  to  Prepare  Modified 
Milk  Mixtures  for  Percentage  Feeding  of  Infants  ? 
R.  H.  Lackey. 
A  negative  reply  is  furnished  by  the  author,  who  forms  his  opinion 
upon  some  practical  experience  in  making  modified  milk  mixtures 
at  home.  It  is  stated  that  the  success  of  the  use  of  such  mixtures 
is  dependent  upon  four  factors  :  (1)  The  direction  of  a  physician  who 
thoroughly  understands  the  method.  (2)  The  selection  of  a  milk 
free  from  infection,  preferably  a  certified  milk.  (3)  The  intelligent 
carrying  out  of  the  physician's  instructions  in  the  daily  preparation 
of  the  food.  (4)  The  proper  equipment  for  the  Pasteurization  of  the 
mixture  and  the  refrigeration  of  the  product. 
To  properly  carry  on  this  work  would  require  a  special  laboratory, 
an  extensive  sterilizing  outfit  and  a  large  refrigerating  capacity,  and 
the  loss  from  unused  stock  would  be  considerable.
