Auerbach and Barschall present a comprehensive study of the 
nature and composition of aqueous solutions of formaldehyde, in- 
cluding a review of the work previously recorded, a full description 
of methods of analysis, the determination of the various constants and 
the consideration of the several theories that have been advanced 
regarding solutions of formaldehyde. — Arb. a. d. Kais. Gesundheits-
