Excerpt from Transactions, American Society of Heating and Ventilating Engineers, Vol. 29: Twenty-Ninth Annual Meeting, Washington, D. C., January 23 26, 1923; Semi-Annual Meeting, Chicago, Ill., May 21 23, 1923 Another conclusion that we are very glad to record is the effect of high temperatures and of high humidities on physiological reactions. We have heard a great deal said about what is the extreme temperature in which man can live at rest. Nobody knows that; everybody will know now. But through the co-operation of the United States Public Health Service and the engineers of your Laboratory there has been determined a positive limit of combined dry and wet bulb temperatures at which human beings can exist at rest over prolonged periods. In other words, we are very sure that we can say to you now that 112 deg. Fahr. Dry bulb and 30 per cent relative humidity represents the extreme limit under which man can exist for any considerable time with safety. N ow it was a very interesting thing in getting action of this kind through co - operation. Dr. R. R. Sayers, I think, is responsible very largely for this Scientific triumph. Dr. Sayers was interested in the problem. He took the possibilities of the problem before his chiefs and he was able to induce them to send a number of high class men who have subjected themselves to exacting ordeals, even going beyond the limit of endurance until they had at times to be taken out of the room, and for days afterwards they were in an abnormal physical condition. These sacrificing persons went beyond nature's limit In order to de termine a physical law of value. There are four elements to this particular problem and we are going to give you one of them today. The solution of these four conditions represent perhaps two years' work. Dr. Sayers and I have discussed this matter and we have come to the conclusion that it would take two years to complete the work if the same degree of speed is maintained that we have shown up to the present time. Another paper to be presented today describes an instrument which can be carried into any industry and be used effectively to determine the amount of dust in the atmosphere. Now, gentlemen, whether these facts will thrill you with pride I do not know, but they do me. I can tell about them because I am not responsible for them. I Simply happened to have been associated with a lot of scientists who have achieved and therefore I can say as much about all these results as I like.

Excerpt from Transactions of the American Society of Heating and Ventilating Engineers, Vol. 13: Thirteenth Annual Meeting New York, January 22-24, 1907, Summer Meeting Milwaukee, Wis;, July 18-19, 1907 Astronomers tell us that the sun, as seen through Whirlpools of its own vapor, is not heated even to redness. That it is a dark bodyl Could we but discover the generating formula of the sun's heat, we would be far on the road to successful scientific heating. The time cannot be far distant when the forces of nature will be so understood and utilized that heat rays will be as dirigible as electric forces now are in the transmission of wire less telegrams. We utterly fail in our duty when we devote our energies to the commercial feature of heat transmission to the entire neglect of scientific investigation. One hour each day devoted sacredly to scientific investigation by each member of our Society would hardly bankrupt us and would make us rich intellectually. The Electric Engineer and the Chemist are forging ahead and will overlap our field of duty if we neglect it.
