%X Since 1951 supplies of Ilford G5 electron sensitive nuclear emulsions have been flown by air to A.ustralia. In 1954 it was observed that some batches, when developed soon after arrival, showed an excess electron background which made them unsuitable for the cosmic ray work for which they were imported.
