Ah, Bailey. His name rang a bell.

In his Encyclopedia of Medical Astrology (1933), Cornell reports:
PLUTO?The Planet Pluto?This planet will not be considered in this Edition of this book, as very little is known of it, and at present is considered by many Authorities to be a hypothetical planet. It is also doubted by some Writers as being a part of our Solar system, and is said to be outside of the Earth's Zodiac in the greater part of its orbit. (See Planets). Mr. E. H. Bailey, Editor of the British Journal of Astrology, writes in the October, 1931 issue of his Journal, and says?"I have no belief whatever in the alleged influence of this planet. It is a very great question whether it is a member of our Solar System ... and I would warn my readers not to accept anything at the present time. It is far too early to lay down definite information with regard to a body which may, or may not, have any astrological influence." Also in the November, 1932 issue of the British Journal, Mr. Bailey further says?

"Several correspondents have written me asking for my opinion respecting this planet, and whether I consider it has any real influence in Astrology, and if so, in what way its influence will be felt. Also what sign it rules. To be quite candid, I must confess that I have little or no belief in this planet, and from the evidence which I have obtained personally, and what has been sent to me by students, I see no reason whatever to include it when dealing with horoscopes. It is far too early in the day for students to lay down any definite information as to its influence, real or imaginary, yet one would think from published statements that certain students were fully aware of its action in horoscopes, and knew nearly all there was to be known about it. A number of horoscopes have been sent to me from readers, in which they allege that certain events have been shown by this planet, but in all the cases sent, I have been able to detect the real cause without incorporating Pluto, or any other hypothetical planet."
It is ironic that, seventy-five years after Bailey wrote these words, Pluto was demoted as one of the solar system planets. He was truly a prophet in his own time.
