omen whom I seemed to know by their writings and
portraits when on the earth. At one table sat Mary Somerville,
Leverrier, Adams, La Place, Gauss and Helmholz; at another Dalton,
Schonbeim, Davy, Tyndall, Berthollet, Berzelius, Priestly, Lavoisier,
and Liebig; here were groups of physicists--Faraday, Volta, Galvani,
Ampere, Fahrenheit, Henry, Draper, Biot, Chladini, Black, Melloni,
Senarmont, Regnault, Daniells, Fresnel, Fizeau, Mariotte, Deville,
Troost, Gay-Lussac, Foucault, Wheatstone, and many, many more. At a
small table immediately beneath a dome of glass, through whose softly
opaline texture an aureole of light seemed to embrace them, sat
Franklin, Galileo and Newton. It would be impossible to describe to you
my amazement at the astonishing picture.

"It almost seemed as if the air vibrated with the excitement of its
impact and use, as these giant minds conversed together. Endowed again
with youth, scintillating, brilliant, the flush of a semi-immortality
impressed upon their faces, which again bespoke the eminence of their
intellects, in picturesque and effective, almost pictorial groupings,
this wondrous gathering filled me with new rapture. My comrade led me to
other branching halls similarly occupied. Chemists were here
conspicuous--Chevreuil, Talbot, Wedgewood, Daguerre, Cooke, Fresenius,
Schmidt, Avogadro, Liebig, Davy, Berthollet, and many, many more.

"It formed an equally striking scene. I turned to my companion and asked
him how it was that the mathematicians, chemists, physicists,
astronomers, were so crowded together. He said, 'The Patenta covers,
with all its buildings, a space about one mile square, and here in
laboratories and in the great observatories these men have flocked
because of a sympathy in their tastes and talents. Although astronomy is
the great profession, and, as I will show you, the marvels of the
Universe are being more and more fully known, yet the study of the
elements and the laws of matter is popular and also followed
unremittingly. It is true that we know these people are from your earth;
they have reported all that to the Registeries, to whom I will soon
conduct you; they yet retain strong memories of the earth, though it is
confined more largely to knowledge than to experience. In some, the
Martian life and habit has almost obliterated their earthly notions and
designs. It is singular that of the scientific workers of the earth the
astronomers, physicists, and chemists alone
