I have no deep point of theory to bring before you and dilate upon, but merely a few plain simple facts, important only in their application to a useful purpose in the light- ing and ventilation, especially, I may say, of light-houses. I shall endeavour to use the plainest and simplest lan- guage for the purpose of conveying my ideas in the clearest and most elementary form to your minds. I am perfectly satisfied that the matter itself, when fairly brought before you, is the only thing that I need recom- mend to your attention. I have the honour of being engaged, or connected with the Trinity Flouse, in reference to certain points on which they may think I may be useful to them in advising and observing upon certain of their light-houses ; this has led me to think of the ventilation of their lights, for a purpose which will almost immediately be evident to you, and which is highly important in the present state of things. I am also, and have been from the first, a member of the Athenmum Club; and there again different circum- stances have called my attention to the same point—the possibility of well ventilating lights. I use the word “ventilation” in its common sense, as meaning only the mode of withdrawing from places where human beings are to live and move, the bad atmosphere which light itself gives forth from the evaporation, and so leaving the air in its undisturbed and natural condition, in which alone it can be useful to man. And now I will adduce the facts, as briefly as I can lay them before you, which have been the result of these
