Bova: T' - Z waa wary muoh Interested In your letter of tehruary 12th dseorlblng the notion of synthetics caltlua ellloate which you are developing. The Samples of material Just arrived this eftemocA and we htfve had a preliminary work at then. I would suapeot that they might be a aource of respiratory difficulty but that point aannot be answered until we ob tain considerable more Information. r ~ ; Va will subject the samples to ohemloal and X-ray analysisto be man that there -la no free ellioa In then. Ziftldentally, nay X aak In what form the sllloa cooponent worked? Did you start with an aaorphoue sllloa or was it quarts? At the same time we will attempt to reduce some of the samples to thq^klse that oan be Injected into the lungs of guinea pigs to see whether It la oapable of producing a pulmonary, fibrosis. The physioal properties suggest , that, it might aot like asbestos but of oourse, one would not ears to antlolpate thlm outoome without actual trial.. . . V . s-- . ' Preliminary animal work should be fer . enough advanced after 2 or 4 months to determine whether it would be. desirable to plan, upon- an inhalation experiment. It- the oalolum slUoate should.bo oapable of causing fibroale, then one should ascertain whether it aan be Inhaled from the atmosphere. Zn the mean. time; Z would regard it with aus' plelon and coo that those .who were working In the pilot plant or otherwise exposed were proteoted by respiratore If there are appreciable oonoentratlons In the atmosphere. beoamso stanoes may or that ol your we havi will Wite yo 8ted li} this, material tempting to/dleoover aubpertled similar to/aebeetoe which reaeTlona.

Thus far, ve have found that chrysotlle asbestos is unique, but on super ficial inspection, your produot seen to behave nore like asbestos: than anything ve have discovered.
