mself strongly
about your and your daughter's kindness in aiding him. He much wants
assistance on another point, and if you would aid him, you would greatly
oblige me. You know well the appearance of a dog when approaching
another dog with hostile intentions, before they come close together.
The dog walks very stiffly, with tail rigid and upright, hair on back
erected, ears pointed and eyes directed forwards. When the dog attacks
the other, down go the ears, and the canines are uncovered. Now, could
you anyhow arrange so that one of your dogs could see a strange dog from
a little distance, so that Mr. Wood could sketch the former attitude,
viz., of the stiff gesture with erected hair and erected ears. (466/1.
In Chapter II. of the "Expression of the Emotions" there are sketches
of dogs in illustration of the "Principle of Antithesis," drawn by Mr.
Riviere and by Mr. A. May (figures 5-8). Mr. T.W. Wood supplied similar
drawings of a cat (figures 9, 10), also a sketch of the head of a
snarling dog (figure 14).) And then he could afterwards sketch the same
dog, when fondled by his master and wagging his tail with drooping ears.
These two sketches I want much, and it would be a great favour to Mr.
Wood, and myself, if you could aid him.

P.S.--When a horse is turned out into a field he trots with high,
elastic steps, and carries his tail aloft. Even when a cow frisks about
she throws up her tail. I have seen a drawing of an elephant, apparently
trotting with high steps, and with the tail erect. When the elephants in
the garden are turned out and are excited so as to move quickly, do they
carry their tails aloft? How is this with the rhinoceros? Do not trouble
yourself to answer this, but I shall be in London in a couple of months,
and then perhaps you will be able to answer this trifling question. Or,
if you write about wolves and jackals turning round, you can tell me
about the tails of elephants, or of any other animals. (466/2. In the
"Expression of the Emotions," page 44, reference is made under the head
of "Associated habitual movements in the lower animals," to dogs and
other animals turning round and round and scratching the ground with
their fore-paws when they wish to go to sleep on a carpet, or other
similar surface.)

LETTER 467. TO A.D. BARTLETT. Down, January 5th, [1871?]

Many thanks about Limulus. I am going to ask another favour, but I do
not want to trouble you to answer it by letter. When the Callithri
