Meteorology of the Indian Ocean

MR. ALLINGHAM submits that information with respect to fog probability is both useful and necessary to the seafarer. I do not deny the usefulness; what I implied was that in the present state of meteorology no adequate information of fog probability could have been conveyed to sailors by making charts of fog from the observations for the region under consideration. The charts showed the northern limit of the region in which the sailor might expect fogs, and this was stated in my article.
