From H. M. W. Baynes   30 January 1882

Rose Cottage, | The Vale: | Hampstead. N.W.

30th. Jany. 1882.

Dear Sir,

May I venture to tell you of a remarkable case of inheritance manifested in early infancy?

As a youth I had, for a long time, a trick of putting my thumb between the first & second fingers of the right hand, generally whilst reading, but more or less upon all occasions.

Our baby, which was born on the 24th. May last year, was noticed by his mother,1 as early as the beginning of August, to place & keep the right thumb between the same fingers of the right hand. This he has frequently done since.

Is not this a clear case of instinctive predisposition manifested in visible action?2

With the profoundest respect for your scientific achievements, | Believe me, Dear Sir, | Yours very sincerely | Herbert: Morton: Baynes
