20% BENZOL MIXTURE.

The figure for aromatic content obtained on the Eagle XV Type Test was low for a 20% mixture.

In view of this, a special sample has been selected and forwarded to A.I.D. Test House, Kidbrooke, for examination. The result is attached, and it will be seen that the aromatic content is 29.2% as against 17.8% on the previous occasion.

These results rather suggest that there may have been separation in the main tank on the previous occasion and I would suggest that suitable precaution be taken to prevent any possibility of this on future Type Tests.
