552 #112,034 equal to the time required for a wave to travel around the semicircumference. To make up for this discrepancy applicant has set the value of v to be 4.7124 x 10¹0, instead of the value 3 x 10¹0 determined by Maxwell, Rowland, Hertz and many other distinguished physicists, such as Webber & Kohlrausch, Ayrton & Perry and Kelvin. Applicant's value of v is 1/57 times the value heretofore established. This factor, 1.57, is equal to or the ratio of semi-circumference to diameter. If applicant's value of v is correct, there is no discrepancy between the first and third essential requirements aforesaid. However, applicant's startling discovery that the eminent physicists, heretofore considered authorities, are wrong in their determination of v.must be rigorously substantiated,- otherwise the first essential requirement should be revised. It is noted that none of the three essential requirements were in this application as originally filed. An affidavit under Rule 48 must therefore be filed stating that this matter constituted part of applicant's original invention. If necessary to revise the first essential requirement as above indicated, to set forth the necessity of having the semi-circumference an odd multiple of the quarter wave length, it would seem that this would involve a departure from the original specification and that the matter would be inadmissible under Rule 70. 2 The best way out of the difficulty would be to cancel all reference to the first and third, and possibly the second, essential requirements, and submit a showing of operativeness together with the constants of the apparatus as a substitute G.
