He considers the information obtained in that investigation asconfidential and not subject to publication at present. I will make a sketch on the blackboard to illustrate some ofthe conditions Mr. Driscoll refers to. for while the location ofthe neutral zone is an elusive problem. I believe it is a problemthat engineers must solve as nearly as it can be solved in anybuildinir thev mav have under We will assume that the sketch is a cross section of a build-ing of seven stories, with an open stair or elevator hall fromthe ground floor to tlie roof. In such a building the neutralzone would be differently located on each floor due to the influ-ence of the hallway. If the conditions were the same on each floor the location ofthe neutral zone would be approximately as shown by the ground floor zones would be about at a. b. The next floorat c, d and so on. If there is a street door in the ground floor and an openinginto the hallway at O, the condition mentioned by Mr. Driscollwould obtain, in which case the neutral zone might be takenentirely out of the ground floor room and equalize in the hallabout at dotted line P, the exact location varying up or downwith the difference in temperature between the inside and out-side air and the size of the openings entering into and out ofthe grou
