ead bird is surrounded by a
flood of curved interwoven threads of emotional disturbance. A strong
vortex is formed by a feeling of deep sadness. Looking at this most
interesting and suggestive series, it is clear that in these pictures
that which is obtained is not the thought-image, but the effect caused
in etheric matter by its vibrations, and it is necessary to
clairvoyantly see the thought in order to understand the results
produced. In fact, the illustrations are instructive for what they do
not show directly, as well as for the images that appear.

It may be useful to put before students, a little more plainly than has
hitherto been done, some of the facts in nature which will render more
intelligible the results at which Dr Baraduc is arriving. Necessarily
imperfect these must be, a physical photographic camera and sensitive
plates not being ideal instruments for astral research; but, as will be
seen from the above, they are most interesting and valuable as forming a
link between clairvoyant and physical scientific investigations.

At the present time observers outside the Theosophical Society are
concerning themselves with the fact that emotional changes show their
nature by changes of colour in the cloud-like ovoid, or aura, that
encompasses all living beings. Articles on the subject are appearing in
papers unconnected with the Theosophical Society, and a medical
specialist[1] has collected a large number of cases in which the colour
of the aura of persons of various types and temperaments is recorded by
him. His results resemble closely those arrived at by clairvoyant
theosophists and others, and the general unanimity on the subject is
sufficient to establish the fact, if the evidence be judged by the usual
canons applied to human testimony.

The book _Man Visible and Invisible_ dealt with the general subject of
the aura. The present little volume, written by the author of _Man
Visible and Invisible_, and a theosophical colleague, is intended to
carry the subject further; and it is believed that this study is useful,
as impressing vividly on the mind of the student the power and living
nature of thought and desire, and the influence exerted by them on all
whom they reach.

THE DIFFICULTY OF REPRESENTATION

We have often heard it said that thoughts are things, and there are many
among us who are persuaded of the truth of this statement. Yet ve
