ACKNOWLEDGEMENTS
Iam grateful to Dr. L. A. Símonarson for valuable
discussions and assistance. The manuscript benefitted
from critical reading by Professor Th. Einarsson and
Dr. L. A. Símonarson. I am also indebted to Dr. G. S.
Boulton, who read an early version of the bi'blio-
graphical review, which was included in my thesis on
the Breiðavik Group on Tjörnes.
