This chapter describes how John Henry Comstock was asked to represent Cornell University at the celebration of the 250th anniversary of the Royal Society of London in 1912. On the evening after the Comstocks' arrival in London, Henry went to the first informal meeting of the delegates to the Royal Society Celebration. On July 16, 1912, there was an impressive service in Westminster Abbey, which was attended by the delegates who were all in Academic dress. That evening, there was a great dinner in the Guild hall for the delegates. Eleven of the wives of delegates, including Anna Botsford Comstock, were entertained at dinner by Lady Bradford at her home in Manchester Square. The closing event of the celebration was the garden party at Windsor Castle. The delegates were received by their Majesties in the palace and were shown through it afterwards. Henry then attended the International Congress of Entomologists in Oxford in August of 1912.
