My Dear Sir,

In your book you amend some observations in the first edition, about the regrowth of an amputated thumb on account of imperfection in the evidence.¹

In 1862 or 3, when a pupil in Edinburgh I assisted my master to amputate half of a double thumb in a newly born infant. In three or four months it has grown again completely & was again amputated. The operator was M^r. M^cKenzie Edward, who is dead² & I have no evidence of the case but a very vivid recollection of every detail. The case occurred in the practice of D^r. Sinclair to whose memory I have tried to recall the circumstances but without success. His answer I enclose as he gives a fact in support.³

You need not answer this unless there is any further information you may desire.

I have just corrected proofs of my first notice,⁴ | Yours faithfully, | Lawson Tait
