§ Sir J. HARMOOD-BANNERasked the Secretary to the Admiralty whether there has been any adoption by France, Italy, or Great Britain of improved service of light on lighthouses and lightships, so as to avoid the silhouetting of ships when coming under the forces of light; and whether the successful use of an improved system is in force by all the Allies?
§ Dr. MACNAMARAAll powerful lights in the United Kingdom are very considerably reduced in clear weather, to obviate the silhouetting effect, and I understand the French and the Italians have also done the same in certain instances. This has greatly lessened the danger, but has not entirely got over it, and further action is under consideration.
