✦ Synopsis

Abstraet N-Ammoaza-3-blcyclo[3 3 Ojoctane was detemuned III dilute (< 3 X 10v3 mol 1-l) aqueous solution by ultraviolet spectrophotometry after reaction with an excess of formaldehyde m buffered solution at pH 6 9 The absorbance of the resultmg hydrazone was measured at 237 nm (molar absorptmty = 5352 1 mol-' cm-') The technique IS particularly well adapted to studies of reaction kmetics using monochloramme 111 strongly alkahne solution (0 l-4 mol 1-l NaOH)

## Abstract The sources of errors likely to arise in the estimation of minute quantities of SO~3~ in gases containing much larger quantities of SO~2~ are discussed with particular reference to boiler flue gases. A laboratory method is described whereby these difficulties in estimation may be elimin
