R. P. Doxford drew The Engineers' Editors attention to the fact that they had published sketches of the low-pressure connecting rods of the 27-knot destroyers Haughty and Hardy, and the 30-knot destroyers Violet and Sylvia in their article dated 1st of September 1899 ('The Bullfinch disaster No. 1.' The Engineer, vol. 88, 1 September 1899, pp. 222-223). The engines of these boats had four cylinders including two low-pressure ones, and the connecting for these had been made lighter than those of the high and intermediate-pressure cylinders. R P Doxford included a sketch of the connecting rods of the Violet and Sylvia to illustrate his point.
