We have observed the Kleinmann-Low Nebula in Orion and detected the J = 17..-->..J = 16 transition of CO at a flux level of 7 x 10/sup -17/ W cm/sup -2/. Our best estimate for the total mass of hot, T> or approx. =750 K, carbon monoxide in the nebula is 8 x 10/sup 30/ g. From this value we assess the total hydrogen mass at this temperature to be approx.1.5 M/sub sun/. A puzzeling apparent deficit of oxygen in the nebula is discussed.
