CONTENTS.

In a former paper[2] I have discussed the geological structure of Mount Washington and shown that in that mass we have to deal with a conformable series of beds embracing four distinct lithological members. These members are: (1) a lower dolomitic limestone—the Canaan Dolomite; (2) a lower schist member containing usually abundant garnets and frequently also staurolite—the Riga Schist; (3) a calcareous member, in the valley a marble but on the summit plain of the mountain and along its base very micaceous and graphitic—the Egremont Limestone; and (4) a schist member very feldspathic and
