Certain carbonate deposits in the Upper Jurassic succession of the western High Atlas mountains of Morocco are interpreted as having resulted from periodic storms operating on very shallow marine or supratidal sediments.

Volcanic ash falls, the oldest laid down approximately 2500 years ago, are described and correlated wherever possible. Most of these ash deposits are thought to have been derived from the Garbuna volcano, located about 40–50 km from Cape Hoskins. Clay mineral data show with increasing age a weathering sequence in the beds in which allophane changes to halloysite. Charcoal data indicate that large amounts of halloysite are present in fossil soil horizons dated between 300 and 2000 years B.P....

PAULING1 has suggested that a high intake of vitamin C may be necessary for optimum cerebral function including learning and memory. We have tested this hypothesis in a preliminary way by comparing maze learning in two groups of guinea pigs: those receiving large supplements of ascorbic acid (the ‘control’ group) and those receiving a daily quantity of the vitamin sufficient to maintain a concentration in the brain at approximately 25% that of the controls (the ‘deficient’ group).

One of the purposes of the Survey of Language Use and Language Teaching in Kenya, which Professor Whiteley directed, was to gather information that might help to clarify the nature of the problems faced by language teachers. One of my concerns in the Survey was to investigate problems that were encountered in the teaching of Swahili at secondary level; and in this paper I would like to outline and discuss some of the information obtained, regarding such problems and the factors to which they can be attributed.
