Mr. J. S. Mitcalfe said, he had particulars of about 150 ships which had been burnt at sea, and he believed there were only two amongst the number which were not ventilated. The others were either thoroughly ventilated, partially ventilated, or had the hatchways ventilated.

It appeared, also, that when the coal was in the condition known as "small," presenting a very large surface to oxidation, it was liable to spontaneous combustion. It was also in a condition of allowing a certain amount of air to circulate through it.
