My dear Sir
I may have been led away by my imagination in fancying that one side of the face in the photograph of the holy Mary of Egypt expresses repentance and sorrow ⟨&⟩ the other devout joy. I shall feel honoured by your retaining the photograph and pleased if you can get any other person to see in it the same expressions that I fancy it2 ⟨2 or 3 words⟩ beginning to read the last sentence of your letter I felt a glow of pride come over ⟨me⟩ but I had barely finished its perusal when I remembered the story of Apelles & the cobbler and at once perceived its remarkable applicability.3 No d⟨o⟩ubt the cobbler would have been glad to paint pictures like Apelles and I should have been delighted to write your book on Expression—if I could. However I have ere now taken to heart the painters advice ⟨several words⟩ crepida⟨m⟩4 ⟨several words ⟩ be allowed to ⟨several words⟩ which you may per⟨ ⟩ ⟨1 or 2 words⟩ of use. I do not know whet⟨her⟩ you have noticed Dr. Ferriers ⟨obser⟩vation that when he irritated a certain ⟨co⟩nvolution of the brain gently the paw of the animal moved but when the irritation was a little stronger it spread to the neighbouring ⟨co⟩nvolution which regulated the movements of the mouth.5 The retraction of the angle of the mouth ⟨about 4 words⟩ movements of ⟨4 or 5 words⟩ thinks ⟨3 or 4 words⟩ of the right angle ⟨2 or 3 words⟩ often seen in carpenters ⟨1 or 2 words⟩ a C⟨ ⟩ in with ⟨ ⟩ right hand is due to the violent excite⟨m⟩en⟨t⟩ in the one convolution spreading to the other. I cannot at present lay hands on my copy of the West Riding Asylum reports to see whether the convolutions for listening ie. pricking up the ears & opening the mouth are adjacent or not but it seems possible that these also may be connected in the same way as the movements of the hands ⟨3 or 4 words⟩ mouth.6 Ferriers expressi⟨ons⟩ certainly show that irr⟨itation⟩ of some parts of the brain may cause movements of muscles on the other side of the face only although irrit⟨a⟩tion of other parts will cause movements extending to both sides. Now as Dr. Crichton Browne7 tells me that the convolutions on the two sides are symmetrical in idiots but become more ⟨and⟩ more un⟨symmetri⟩cal until ⟨ ⟩ becomes developed it ⟨ ⟩ probable that in the same proportion we may look for differences between the two sides of the face whenever the facial muscles are set in action by stimuli from the brain. In maniacs the two sides of the brain are very unsymmetrical and in them I think twitchings & contractions of one side of the face are often observed which I think they ⟨3 or 4 words⟩ I will ask Dr Browne about ⟨ ⟩ however so as to be cer⟨tain⟩ Mr. Ernest Hart tells me that Americans have a general notion that girls with a cast in their eyes have more expressive faces than others and that some girls of high culture & mental power get a slight ca⟨s⟩t in their eyes when excited.8 He instanced one, a daughter of Dr. Marion Sims9 who had this & she, he says, certainly had an ⟨1 or 2 words⟩ expressive face ⟨several words over 2 lines⟩
Yours very sincerely | T Lauder Brunton
