With these alterations the apparatus worked well in smooth water, but in bad weather, with the ship rolling, premature releases were still liable to occur. If the wire strayed much from the vertical it would bear on the cotter pin and eventually effect release. During the second year of the commission a different pattern of closing mechanism was made by the engine-room staff and this has been found to be a great improvement on the former model, working 1 Hjort, Depths of the Ocean, p. 48, fig. 31, London, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography; Great Britain.
