✦ Synopsis

Abstract

Methods are described for the routine estimation in ground seaweed samples of mannitol by periodate oxidation, of alginic acid by isolation and the displacement of acetic acid from calcium acetate, of laminarin by hydrolysis to glucose and its estimation with the Shaffer‐Somogyi reagent, and of fucose (after hydrolysis) by periodatc oxidation and estimation of the liberated acetaldehyde.

## Abstract A method is described for the estimation of alginic acid in seaseed samples, using the color reaction with carbazole and sulphuric acid, which can be applied on a micro scale, and is more rapid than the technique previously adopted.
