          an inch and an ell will be taken?


 In making some nitric acid from
 nitre & vitriol I obtained in the residue
 the radiated needle crystals of the 
 [inserted: hydrated] sesquisulphate of Potash of Jacquelin
 & Philipps (2KOSO{subscript 3} +HOSO{subscript 3}) as it
 is rather rare, I set it aside till
 next day (crystals liquor &all) to crystallize
 but upon a second inspection they had
 passed into the flat rombohedral [rhombohedral]
 crystals of Bisulphate. As I never 
 obtained these radiated prisms before
 & Graham says it is [added: not known how they 
 are formed, I can only say that 
 I need a solution of nitro with some
 crystals in Excess & a moderately dilute
 acid.
