From Allen Thomson   31 December 1876

68 Palace Gardens Terrace | London. W.

31st. Decr. 1876.

Dear Mr. Darwin

Your letter with Mr. Balfour’s application for admission to the Royal Society was forwarded to me at this place, where Mrs. Thomson and I have been for a few days on a visit to our son and daughter in law.1

I have great pleasure in signing the application which I now return enclosed. I have not known of any person in this country who in my time has so fully mastered the subject of embryonic development, and who in so short a time has made such valuable contributions by his own observations to the knowledge of its details in the Vertebrata as Mr. Balfour: And I look for very important results from the continuation of his researches.2

I have long had a great desire to renew my acquaintance with you, which if I mistake not dates from an early period in Edinburgh as far back as the days of the Old Plinian Society, and I hope that in the Course of next summer when I may be in London I may have the good fortune to meet with you.3

I return to Glasgow tomorrow to resume my College duties after the holidays.4

Believe me sincerely yours | Allen Thomson
