Expresses gratitude for receiving the paper on Laminaria and the other papers. Has sent all the duplicate species, including a Prasiola marina. Has sent two parcels of algae. Information: Laminaria longicruris is often found cast ashore here, because the sea temperature is higher at the Orkneys than farther south. Nitophyllum punctatum and Callophyllis laciniata are found growing here.
