 Van de Stadt deviated from current usage of modified Hepburn by not using the apostrophe to indicate the long "n" (ん) before a vowel.Sometimes he ignored the special case of ん, other times he used a hyphen (for example, he spelled "kon'ya" for 今夜 but "kon-yaku" for 婚約).The Latin spelling of the title word is followed by the Japanese spelling and equivalents or a definition in Dutch (both of course in prewar spelling).
