Ve have done over 40 different experiaents, nany of then divided into several parts, which involved exposure of anlcals for 1 to 3 years to various dusts. The business of preparing aiero- * C sceplc sections and oheolcally analyzing the tissues on sore than BOO ahlcals has been a lob in itself. -My tiae for studying sections and analyzing data has been so Halted that ve are behind our sched ule. T have still hot had ties to writs a full report of this work which will of necessity be conographic. * However, for the benefit cf the contributors.
