1) () J 371,817 - 2. understood, of course, that the metallic shell must be sunported and insulated in some manner. It is immaterial, so far as this invention is concerned, whether the metallic shell or support be an insulator attached to the shell at or near the point where the metallic support is here shown as connected or whether the metallic support be insulated at a point entirely removed from the metallic shell. The point in the invention is that the support be attached to the shell et a place of low electrical density. Claim 3 is rejected upon Figure 671 of Genot. Cancel the comma after "terminel", claim 6, and change "therefore", line 2, to therefor. A common piece of laboratory apparatus for use in discharging condensers and for transferring electrical discharges is a pair of metal balls at the end of metal rods, the latter hinged together and attached to en insulating handle. Claim 6 is broad enough to be met by this device. The insulating support in this case is secured at a point of low electrical density. Claim 7 is rejected upon the same ground as claim 6. There would be no invention in using such a termaiat as that shown by Kinraide in place of the metel balls. of the Leyden jar discharger mentioned above. Claims 8, 9 and 10 are rejected upon the showing The several bells of veryfound in Genot, Figure 669. ing sizes attached one to the other shown in this figure are connected together at moints of relative low electrical density. Cancel the commas before and after "there for", line. 2, claim 9, and after "surfaces", line 2, claim 10 end insert of after "curvature", line 3, claim 10. 85 371 779
