nded by silk threads, in the
underground magnetic house that you see the top of in the
foreground of the picture. The magnets were sometimes moving about
so rapidly that I could scarcely read them; and although the aurora
was with you nearly at an end probably about ten o'clock, yet the
magnets did not resume their normal position for nearly twenty-four
hours after. You will see from this the advantage to be derived
from noting all particulars with regard to these phenomena,
whenever one has an opportunity of seeing them; for we must always
consider the possibility of their not being visible at places where
there are observatories, on account of clouds and other causes. One
great point that has yet to be satisfactorily determined is,
whether the effect on a magnet at one end of the world is
simultaneous with the auroral discharge at the other; or whether a
certain time is required for the effect to be communicated through
the earth. I had a letter from my father yesterday, enclosing the
one you sent him. By-the-by, this day week is Christmas-day; and,
if I am not mistaken, your birthday as well as Hannah's is near
about this time. She must be thirteen or fourteen; but, upon my
honour, I do not certainly know my own age. Was I born in January
1834 or 1835? I wish you all may have a merry Christmas and many
returns of the same. Please to give my love as usual, and
Believe me, my dear mother,
Your affectionate son,
WILLIAM J. WILLS.

Postponement of the Exploring Expedition projected at the beginning
of 1860. My Son's Letter to his Sister on going into Society. Mr.
Birnie's Opinion of him, and Extract from his Lecture. Letter from
William to his Mother on Religious Views and Definitions of Faith.
His last Communications to his family at Home, before the Departure
of the Expedition.
I OMIT my son's letters of January and February, 1860, as they
contain nothing on scientific matters, or on the subject of
Australia, although interesting in other respects. They mark the
habitual tone of his feelings and principles, his constant habit of
self-examination, his study of his fellow-men, and how strongly he
was impressed with the truth of Pope's grand conclusion, that
"Virtue alone is happiness below."
"You will be glad to learn," he says, writing to his mother on the
17th of March, "that the Exploring Expedition is postponed for six
months, for want of a suitable leader, as none of the candidates
