1 Abstract. On Air Conditioning of the 1. J. G. R. Shimonoseki-Fusan Passenger Ferries the "Kongo -Maru" and " Koan-Maru." By K. Kato, Member. The autlier briefly touches, in the first place, on the signification of " Air Condi'ioning," its origin and development and describes on air conditions v.a.v. human susceptibility. Then he generally exp'ains the methods of conditioning the air, now usually employed and tries a short survey on the present state of air conditioning of communication means such as railway wagons, tram ears on land, and vessels on water. He, finally, enters into the explanation of the design, lay-out and the results of IT ovisional tests of the air conditioning equipments on board the two ships above named, which are not only the pioneer ships in Japan furnished with these equipments, but also the foremost vessels in the world in which the equipments are most extensively employed, viz. all public rooms and all cabins in the quarters for all classes of passengers have been completely air conditioned throughout.
