a continuous development day after day of the doubling of the canals
which seemed to extend along great circles of the sphere. In 1882
Schiaparelli expected at the evening opposition in 1884 to confirm and
add to these observations.

My father had read Schiaparelli's announcements with absorbed interest.
They fed his burning fancies as to the extension of our present life,
and offered him a sort of scientific basis (without which he was
inclined to view all eschatology as superficial) for the belief that we
may attain in some other planet an actual prolonged second existence.

His great reverence for Sir William Herschell was indisputable. He
quoted Herschell's own words with appreciation. These pregnant sentences
were as follows:

"The analogy between Mars and the earth is perhaps by far the greatest
in the whole solar system. Their diurnal motion is nearly the same, the
obliquity of their respective ecliptics not very different; of all the
superior planets the distance of Mars from the sun is by far the
nearest, alike to that of the earth; nor will the length of the Martial
year appear very different from what we enjoy when compared to the
surprising duration of the years of Jupiter, Saturn and the Georgian
Sidus. If we then find that the globe we inhabit has its polar region
frozen and covered with mountains of ice and snow, that only partially
melt when alternately exposed to the sun, I may well be permitted to
surmise that the same causes may probably have the same effect on the
globe of Mars; that the bright polar spots are owing to the vivid
reflection of light from frozen regions; and that the reduction of these
spots is to be ascribed to their being exposed to the sun."
