OBSERVATIONS  UPON  THE  SORGHUM  SACCHARATUM.  105 
COMPOUND  SYKUP  OF  THE  IODOHYDRARGYRATE  OF 
POTASSIUxM  AND  IRON. 
By  Joseph  E.  Young. 
Being  called  upon  to  prepare  a  formula  containing  the  Red 
Iodide  of  Mercury  and  Iodide  of  Iron  in  solution,  to  be  used  in 
cases  of  secondary  syphilis  combined  with  scrofula,  the  follow- 
ing suggested  itself  as  being  a  good  one,  and  an  elegant  mode 
of  administering  the  iodides  in  combination.

Mix  the  iodine  with  three  drachms  of  the  water  and  add  the 
iron  ;  when  combined  filter  into  the  syrup,  (which  is  made  with 
an  ounce  and  a  half  of  the  water,)  the  red  iodide  of  mercury  and 
the  iodide  of  potassium  are  triturated  with  the  remaining  drachm 
of  water  and  added,  the  whole  to  measure  four  fluid  ounces.  A 
little  orange  flower  water  added,  makes  it  very  agreeable.  The 
dose  recommended  is  about  one  teaspoonful,  which  is  equivalent 
to  l-16th  gr.  of  the  red  iodide  of  mercury  and  2f  grs.  of  the 
iodide  of  iron.

EXPERIMENTS  AND  OBSERVATIONS  UPON  THE  SORGHUM 
SACCHARATUM,  OR  CHINESE  SUGAR  CANE. 
By  Joseph  S.  Lovering,  of  Oak  Hill,  Philadelphia. 
[The  above  is  the  title  of  a  pamphlet,  published  last  month,  which  pos- 
sesses so  much  intrinsic  interest  to  the  consumer,  as  well  as  to  the  producer, 
of  sugar,  that  we  have  endeavored  to  convey,  as  correctly  as  possible,  an 
idea  of  its  contents  in  the  following  abridgement.  The  well  known  ability 
and  success  of  Mr.  Lovering,  in  all  that  pertains  to  the  chemistry  and 
manufacture  of  sugar,  give  every  confidence  in  the  accuracy  of  his  results.

The  introduction  of  this  plant  into  the  United  States,  and  the 
hope  of  producing  sugar  from  it  at  the  North,  profitably,  have
