disencumber the central nervous system, which is evidently very badly
depleted of its vital force. It is, of course, a pity the
correspondent cannot get away to a properly organised Nature-Cure home
and have the continuous attention and treatment which her condition
really necessitates.

_To the Editors._

SIRS,

You will see that your little magazine finds its way even to this
out-of-the-way corner of the globe, and you may be sure that it is
appreciated. I am specially interested in Dr V. Knaggs'
contributions and should like to ask him a few questions. May I
say that I have some knowledge of chemistry and that I try and
take an interest in the scientific aspects of food reform.

(1) P. 237. What grounds has Dr Knaggs for speaking so definitely
about human magnetism and that of vegetables? How would he
recognise or test for either, and where can I get further
information (scientific) on the question of food magnetism.

(2) Same page. Dr Knaggs says salt added to cooking vegetables
converts organic salts into inorganic. I cannot follow that. _What_
organic salts are so converted? One or two examples would suffice.

(3) I have been reading Dr Rabagliati's _Conversations with Women
Concerning their Health and that of their Children_.[8] In it he
says that food is not the source (cause) of body energy, but is
used merely to replace waste material. Elsewhere I read that
"Professor Atwater's investigations into nutrition have shown in a
most convincing manner that the body derives _all_ its energy from
the food consumed. This may be regarded as established." Which of
these definite and contradictory assertions does Dr Knaggs support,
and why? Where can I get information _re_ Professor Atwater's
experiments and other recent works on similar subjects?

To me the questions involved are intensely interesting, hence my
queries. I hope they do not read as if I were hypercritical or
sceptical.

With all good wishes for the success of your healthy little
magazine. I am, yours, etc.,

W. BLEWETT.
