A constricted, tight feeling in the chest is usually the first mani festation, and since this symptom is often severest on Monsays, me term 'Monday fever" or'Monday cough" has been applied to it.

The authors compared this case with those of uncomplicated silicosis; m the latter restsual air is frequently increased, expiration is prolonged, and the maximum respiratory capacity ;s reduced, but hyperpnea is less. rapid breaming is not sc -..-.tense, and anoxemia is never so important curing effort, as in asoestosis T cuiercr.css are siressea as important when necessity may arise m determining ne occupational origin of a case wun obscure ciagnosis. -- Cona. from Bull.

Special mention is made o: the association toestnsis with carcinoma, wnich is much more frequent than that of sili.i. Post-mortem reports from the literature indicate that m 309 cases . .isestosis there were 44 lung carcinomas (14.2%), whereas in 2,204 cases -.:cosis only 12 carcinomas were found (1.4%).
