The  Bedford  Springs. 
Am.  Jour.  Pharm, 
Feb.,  1878. 
The  temperature  of  the  spring  has  been  found  58°F.,  while  that  of 
the  surrounding  air  was  jo°F.  Specific  gravity,  1*0035.  10,000  parts 
of  this  water  contain  the  following  quantities  of  constituents  : 
Chloride  of  sodium,  NaCl, 
Sulphate  of  sodium,  Na2S04, 
Sulphate  of  magnesium,  MgS04, 
Sulphate  of  calcium,  CaS04, 
Carbonate  of  calcium,  CaCOs,

The  saline  compounds  were  calculated  from  the  data  obtained  as 
follows  : 
CI  as  NaCl 
(Total  Na)  minus  (Na  of  NaCl)  as  Na2SOv 
iMgO  as  MgSOv 
(Total  S03)  minus  (SOs  of  Na2S04  and  MgSOJ  as  CaSOv 
(Total  CaO)  minus  (CaO  of  CaSOJ  as  CaCOv 
The  latter  result  was  confirmed  by  a  direct  estimation  of  C02  in 
the  dry  residue. 
The  water  was  also  examined  for  the  following  constituents,  which^ 
however,  were  found  to  be  absent,  viz.  :  sulphur,  ammonia,  phosphoric 
acid,  arsenic,  nitric  acid,  potassa,  lithia,  iodine  and  bromine. 
Quantity  taken  for  analysis,  ten  liters.  I  add  an  analysis  of  the 
same  water,  made  in  1825  by  Dr.  Church,  of  Pittsburgh,  Pa.
