were free from the presence of boron preservative, while 12 showed traces only, the
largest amount found being 0.0l grain per pound.
In July a consignment of sweets in bottles arrived from Japan. A sample was
drawn and sent to the analyst, as it appeared that the glass was particularly fragile
and there seemed to be a real danger of a consumer unwittingly swallowing fragments

would take the matter up with the packer.
No further consignment of this nature has been noted in the district.
