Tollens points out that the results of empirical analysis are inconclusive; and that from the acid reactions of these products and their combination with bases, carboxylic groups are present, though probably in anhydride or ester form.

Tollens emphasises this fact in his studies of cellulose-estimation methods.

But the results might, on the other hand, be considered indicative of the anhydride or 'lacton' grouping, which Tollens suggested for lævulose:

This portion of the investigation is an extension of that of Suringar and Tollens, these latter confining themselves to celluloses of the

The original lignone may be regarded as passing into solution as a still condensed complex derived from C_ {24} H_ {26} O_ {12} (Tollens).

The methods of treating with the halogens, viz. bromine water (H. Müller), chlorine gas (Cross and Bevan), and chlorine water, are dismissed with a bare mention, apparently on the basis of the conclusions of Suringar and Tollens
