Generally the discussion of analytical results of a population is restricted to the calculation of an overall mean and standard deviation. In this paper a method is described enabling the direct incorporation of peculiarities in the distribution of t

A modified technique is described which gives reliable and reproducible results for the combustion of organo-germanium compounds. The catalyst used is tungsten trioxide. Essential for good results is a slow combustion which has to be carried out manu
