Boar Bill!
Herewith 1 t>e final report of our studies concerning The Capacity of Inhaled Zaylo Suet to Injure the Lug. V Are enclosing four copies for distribution by you. tea copy has been sent to Doctor Shook for his lnforantlan and vs are retaining a copy for our files.
The results of the investigations vlth anlmls shoe that Zaylo dust ip capable of producing a peribronchiolar flbroals typical of asbeetoaia. Tho dust also has a slightly unfarorsbls Influence upon n tuberculous lnfeetloa. Although extrapolation fTca snl.esl to hau experience is difficult, nevertheless the results of the study indicate that every precaution should bn taken to protect workers against Inhaling the duet. Therefore, control neaeures should be directed to reducing the mis > of atmospheric dust, especially at those points of operation where dust Is generated. Our report of Kay 29. 1951 concerning the Industrial hygiene survey nay be of help to you in this re gard.
Ve hope to publish this study either separately or in acablnatlaa with elslier studies pertaining to other dust. In doing so. however, reference will be eade only te hydrous calcine ellloete and not to *Taylota thus the interest of your Coepaay will be safe guarded. Of course the final aeausorlpt will be forwarded to you for revise before being released to the rublishcr. Tour eoeesnt in this regard would assist na greatly In preparing the naanaerlpt.
Xa subediting this final report, nay X express to you and ethers of the Onupany our sincere appreciation for having had the privilege of collaborating with the Owsee-Illinoio Olass Coepaay la the study of Xaylo. The collaboration has always been aost pleasant and etlenlatlng.
