CORRESPONDENCE. 
F. W. (Brighton) is thanked for his communication. The evidence in the case re¬ 
ferred to is insufficient on which to form an opinion. The particles, if really crystalline, 
as described, would point to oxalic acid rather than oxide of zinc. 
Air. T. J. Monaghan is thanked for his communication.

ants.”

cess than that described in this Journal, Vol. IX. (n.s.) p. 496. 
A. N. (Penzance).—The change is probably due to the formation of a suboxide. 
A. Z. wishes to know where to find “Marsh’s” test for purifying water. Is Clark's
