   • 2012 March 1, William E. Carter, Merri Sue Carter, “The British Longitude Act Reconsidered”, in American Scientist‎, volume 100, number 2, page 87:

     But was it responsible governance to pass the Longitude Act without other efforts to protect British seamen? Or might it have been subterfuge—a disingenuous attempt to shift attention away from the realities of their life at sea. Conditions were horrendous aboard most British naval vessels at the time. Scurvy and other diseases ran rampant, killing more seamen each year than all other causes combined, including combat.
