The armament consists of two bow tubes built in the boat.  There are two turntables, as shown in the illustrations, each fitted with two torpedo tubes.  These, it will be noticed, are not arranged parallel to each other, but lie at a small angle, so that if both torpedoes are ejected at once, they will take a somewhat divergent course.  Messrs. Yarrow have introduced this plan in order to give a better chance for one of the torpedoes to hit the vessel attacked.  There are two quick firing three pounder guns on deck, and there is a powerful search light, the dynamo and engine being placed in the galley compartment.

We believe, says Engineering, this torpedo boat, together with a sister vessel, built also for the Italian government, are the fastest vessels of their class yet tried, and it is certain that the British Navy does not yet possess a craft to equal them.  It is an extraordinary and lamentable fact that Great Britain, which claims to be the foremost naval power in the world, has always been behind the times in the matter of torpedo boats.

The official trial of this boat was recently made in the Lower Hope in rough weather.  The following is a copy of the official record of the six runs on the measured mile:
