try  of  the  salt  used,  that  it  challenges  the  respect  of  the  profes- 
sion ;  but,  while  so  chemically  correct,  it  has  been  found  in  prac- 
tice that  the  free  use  of  phosphoric  acid  in  many  cases  is  not  un- 
attended with  disadvantage  ;  the  more  so,  as  the  class  of  persons 
intended  to  be  benefitted  by  the  syrup  in  question,  cannot  endure 
the  slightest  diarrhoea  without  being  much  injured. 
Yet  the  use  of  the  phosphates  of  iron,  lime,  soda  and  potash, 
has  proven  satisfactory  in  the  hands  of  several  of  our  first  physi- 
cians, and,  in  view  of  these  facts,  it  was  thought  that  a  formula 
avoiding  free  phosphoric  acid  might  be  of  use :

Dissolve  the  phosphate  of  lime,  previously  mixed  with  an  ounce 
of  water  by  means  of  the  acid,  filter,  then  add  the  remaining 
water ;  to  this  add  the  sugar,  until  the  bulk  is  increased  to  twelve 
fluid  ounces,  and  strain. 
SYRUPUS  MANGANESLE  PHOSPHATIS. 
By  Thomas  S.  "Wiegand. 
The  attention  of  the  medical  profession  having  been  called  to 
manganese  as  a  remedial  agent,  and  many  writers  having  recom- 
mended it  as  suitable  to  those  cases  in  which  the  ferruginous 
salts  were  inapplicable  by  reason  of  their  tendency  to  produce 
headache,  it  was  thought  that  a  phosphatic  salt  of  manganese 
would  be  preferable  to  any  other  preparation,  as  the  phosphates 
generally  have  been  found  advantageous  in  anemic  conditions  of 
the  system.  To  be  a  satisfactory  preparation,  it  should  be  in  solu- 
tion and  unalterable  by  exposure  to  the  air. 
The  following  formula,  combining  these  pre-requisites,  is  of  such 
a  strength  that  each  fluid  drachm  contains  five  grains  of  phos- 
phate of  manganese ;
