coastal belt the rocks are sedimentary and range in age from 
Cretaceous to Recent. The author divides them into three groups: 
(1) sandstones with fossils; (2) limestones belonging to the late 
Cretaceous and early Tertiary; and (3) sands and clays (probably of 
late Tertiary age) surmounted in places by recent sand dunes and 
other deposits. The topography of the country seems to approximate 
to the ‘inselberg’ type of landscape, for Mr. Soper describes it as 
‘‘characterized by great undulating plains, abrupt mountains, rocky, 
steep-sided hills, and peaked serrotes””.—A. H.

f{\HE author describes two differentiated laccoliths of nepheline 
syenite that lie in a syncline of limestone between large areas of 
Laurentian gneiss. He then discusses the origin of the alkaline 
intrusions, and states his agreement with Professor Smyth’s opinion 
that nepheline and sodalite rocks are results of the pneumatolytic 
phase of igneous activity in certain circumstances. In this instance 
Mr. Foye suggests that the controlling circumstances consisted in 
the desilication of granite magma during its lit-par-lit injection into 
the Grenville limestones. ‘‘Soda solutions were given off by the 
granite magma because lime was capable of replacing soda at high 
temperatures”’ (p. 434). From granite and limestone as the parent 
materials, amphibolite and nepheline syenite were, it is believed, 
thus derived, and the close field associations of these four types of 
rock provides the theory with an assemblage of facts that ought on 
further elucidation to lead to its complete demonstration.— A. H.

At a meeting of the Society on October 12, Mr. G. W. Tyrrell 
exhibited, on behalf of Mr. B. K. N. Wyllie, a number of Stone 
Age artifacts from Northern Ashanti. These are of three types: 
(1) rough chips and flakes of quartz; (2) chisel- or celt-shaped 
polished stones; (3) artifacts with a herring-bone or cross pattern. 
The first two types are common throughout the Gold Coast Colony, 
but the third is rare, the specimens exhibited being found at Temma, 
100 miles north of Coomassie, in a remarkable natural stronghold. 
The latter consisted of a rectangular block of current-bedded sand- 
stone, 200 to 300 yards long by 100 yards broad, and nearly 200 feet 
high, standing with sheer walls on the low slope at the side of a wide 
valley. The patterned objects and the celts were found on the floor 
of a small cirque inside this, which may have been adopted as a fortress 
or a fetish monastery by an earlier race of inhabitants; the local 
Ashantis display utter ignorance of the originators of these things, 
and their fetish methods are totally different. A piece of iron slag 
was also found inside the cirque.
