American Society of Heating and Ventilating Engineers Guide, 1932 Of course, where the required heating surface is estimated by empirical or rule-of-thumb methods, refinements in approximating fuel consump tion are not warranted, but rule-of-thumb methods often lead to unsatis factory results and should be avoided in heating work where more accurate methods are available.

Certain sections of the building, such as offices and rooms which are partitioned off from the larger areas, may be heated by ducts leading from indirect heating units supplied with'hot water in parallel with the unit heaters.

In foggy weather the accumulation of these substances in the lower strata may be such as to cause irritation of the eyes, nose, and respiratory passages, leading to asthmatic breathing and bronchitis and, in extreme cases, to death.

During this time period, I would conclude that the medical literature might lead the reader to the opinion that the association between asbestosis and lung cancer was now "probable". 3 Finally, the last time period is 1955 until the present,' This phase, of course, began with the publication by Richard Doll using the rr.ost valid epidemiologic techniques up to that time to investigate a causal asso ciation, i. a. , a cause-specific mortality study of workers with defined employment in a specific plant.

We discussed various general problems and parti cularly the value of urine and faecal analysis in establishing lead poisoning.

Air of proper warmth may, for in stance, contain excessive water vapor, and in this way interfere with the normal physiologic loss of moisture from the skin, leading to damp skin and clothing and producing more or less discomfort; or the air may be excessively dry, producing appreciable discomfort to the mucous mem brane of the nose and to the skin which dries up and becomes chapped from too rapid loss of moisture.
