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, Hans Delbrück. 222. From Henry S. Hatfield 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] [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. 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.
