D O C U M E N T 2 2 5 J U N E 1 9 2 2 1 8 3 me, it had been resolved anyway not to touch the guilt issue on Sunday. Hopefully we really shall succeed in preventing transgressions of this limit. In utmost respect, yours,[9] Hans Delbrück. 222. From Henry S. Hatfield[1] Berlin, Kurfürstenstr. 124, 7 June 1922 [Not selected for translation.] 223. From Gustave Le Bon 29 Rue Vignon Paris, 7. VI. 22 [Not selected for translation.] 224. From Heinrich Zangger [Zurich, between 8 and 18 June 1922][1] [Not selected for translation.] 225. From Hermann Anschütz-Kaempfe Kiel, 9 June 1922 Dear, esteemed Professor Einstein, Of course the money will be disbursed on time to the new address you indicated.[1] I have had good and less-good experiences with the new apparatus, i.e., the blow sphere, but none of them entirely amiss. The bakelite did not work out it evidently does not tolerate the acid I have to add to the water however, I now have the sphere covered with a layer of hardened rubber and have been getting quite good results. At the present time I am trying to enrich the hard rubber intensely enough with car- bon powder through vulcanization to make it conductive at the current contact points. I don’t know yet whether it works, but it would be very elegant.[2]
