Analysis of the flue dust of the h plants of the fbundry gave the following % data; Zn53*5, 5.21, 51*.0, 23.1;; Pb 5-2, 1^.8, 7.8, 16.9; S5.2. 8.2, 5.1;, 12.5; Cla 0.8, 5.6, 0.2, Cd -, -, 1.7, 2.2; As 0.07, 0.2, O.lj, 0.5; Fb traces, -, -, -; F-, -, -, 0.05. The animals ingesting the vegetatioil and in haling the flue dust while grazing, showed characteristic symptoms of chronic O and acute Pb intoxication. They became emaciated rapidly and developed' cachexia^ paralysis and stiffness of the Joints; milk production decreased. The foundry N \ ! granted a compensation for dead animals when a Pb content of at least 0.2 mg. Pb/LOOg. liver substance had been proved. Findings on 3 affected colts grazing near the foundry were reported in detail. Two of themhad a leuoo- cytosis. The Pb content in their livers, per 100 g., was 0.37, 0.23 and 0.39 mg., the Cu content 3.1;, 1.0 and 1.9 mg. In experiments carried out by the Veterinary School in Hannover, a eolt and a sheep were fed hay grown around thoj foundry (containing 60-65 mg. Pb/kg*) and flue dust collected fromthe Fb founcty 28 27 Z Y X W V U S ROP ONML KJ HGF EDCB II I' 17 18 19 21 22 24 25 26 27 28 30 31 32 33 34 35 36 37 38 39 40 41 4 2 43 Giinther, H.: 2(M2id.8a$. aRn>d) w20ithg./tdhae.irforartiaonno.thTehre7cdoal.t reIctebiveecdam5e.gu*naobflethtoisswdualsltow3,titmhees/day for Btnoous membranes showed an icteric discoloration, leucocytes increased greatly.
