Nikola Tesla, 27, Paper No... 12 All communications respecting this application should give the serial number, date of filing, and title of invention. F.H. DEPARTMENT OF THE INTERIOR, UNITED STATES PATENT OFFICE, WASHINGTON, D. C., c/o Kerr, Page & Cooper, 149 Broadway, Sept. 30, 1909. 50 1909 New York, N. Y. Please find below a communication from the EXAMINER in charge of your application, S. No. 371,817, filed May 4, 1907, Apparatus for Transmitting Electrical Energy through the Natural Media. Billsore. Commissioner of Patents. This action is in response to amendment filed Aug. 1909. Page 2, line 18, after "so" cancel the comma. Considerable confusion exists throughout the specification and claims in regard to the use of the terms "large curvature" and "small curvature". It is pointed out that a large sphere is a body having a large radius of curvature but having small curvature, whereas & small sphere is one having a small radius of curvature but a large curvature. Attention is called, for instance, to the sentence commencing in line 20 of page 2. This is not in agreement with statements made by applicant in other parts of the specification. The same inconsistencies occur in the claims. Attention is called, for instance, to claim 10 in which applicant calls for one or more surfaces of smaller curvature to permit the escape of the charge at a predetermined density. Applicant has as a matter of fact shown in the figures and explained in the specification that the surfaces for permitting this escape have larger curvature, that is, are surfaces of small radius of curvature. Later, in such claims as 15, 16, &c., 371 57 59 755
