Using h Warburg reapirometer and freshly-prepared guinea pig lung, studies were made of the effect r it > of bagasse dust on the respiratory quotient and on thu activity of malic dehydrogenase, lacth /' dehydrogenase, cytochrome oxidase, fumaraee, adunosins. tryphosphatase, and tronsamtni.-, * * There was no noticeable change in the respiratory quotient or the activity of the first 4 may,,.., but there was an appreciable enhancement of the latter 2 entymei in the presence of 1 % bug**, se dust, In the esse of succlnie dehydrogenase the effect of the whole bagasse, as well as it.- '* water-soluble extract, was studied. The former inhibited but the latter did not have any af(i: \J.- at all on the activity of the ensyme. -- APCA Absu.

An attempt has been made to determine whether any asaoeu* . lion could be eatabliahed between tho numbers of viable bacteria and fungi in the air of 2 cotic. and 2 jute mills, and the prevalence of byssinosia. No association was found except between u the numbers of live organisms of B. pmnilus end B, Subtilis, and the occurrence of byssinosi., . This association doc* not establish a cauial relationship, but it is suggested that an attempt should b made to produce typical symptoms in byssinotlc subjects by mean* of organism* o!
