Some typical analyses of red seaweeds

The seaweeds with which this paper is concerned all belong to the group Rhodophyceae, the best known of which are Gelidium spp. and other genera, from which agar is obtained, and Gigartina spp. and Chondrus spp., collectively known as Irish moss. This work was carried out under the auspices of the Institute of Seaweed Research with a view to obtaining a comparative survey of the general analytical characteristics of the group as a whole, although particular attention has been devoted to the distribution of the various sugars present (as shown in Table II).
