A number of communications dealing with the origin and composition of the material commonly known as laterite have appeared in the Geological Magazine during the past few years. That of Dr. Maclaren is an especially valuable contribution to the literature of the subject, and I think few workers in the Tropics will be disposed to question the substantial accuracy of his conclusions. I shall not attempt, therefore, to discuss the general problem presented by the widespread occurrence of laterite deposits in tropical regions. The object of the present brief communication is merely to place on record a few observations made in another area.
