Perhaps the first comment to make is that it was published by Teubner of Leipzig, probably partly because of Klein 's advice, but mainly because there was no well-established American scientific publisher.
Marahil ang unang puna sa gumawa ay na ito ay nai-publish sa pamamagitan ng Teubner ng Leipzig, marahil nang bahagya dahil sa Klein 's payo, ngunit pangunahin dahil doon ay hindi maayos-matatag na pang-agham American publisher.
