Abstract
THE existence of ‘clay fulgurites’ from Kingston, Ontario, was reported recently by Hawkins1. These were described as “partially fused ellipsoids” resulting from lightning striking clay sediments. The report was of considerable interest to us because it suggests that lightning may be responsible for the formation of tektites. At our request, Dr. Hawkins kindly sent us a sample of this material. The composition is as follows :
