Transcription

June 8th

My dear Lucy

I hear that your Dog is a barker: please observe for me whether the (upper) lips are at all retracted or everted when he barks & just before he barks. My impression is that if you open a dog’s mouth lips almost hide teeth; but that they are much more exposed, when he barks, which implies some contraction or eversion.

You are so good an observer that I know I can trust your conclusion. The Bark ought not to be a savage one, as that wd give tendency to snarl— a joyful bark or bark of good spirits wd. be best.—f2

Think of any fact about expression of any emotion in any of your birds.—f3

Yours affect. | C. Darwin

Our Pollyf4 will not bark except as she rushes away to some supposed enemy in forest.
