Professor Edward Granville Browne visited 'Abdu'l-Bahá on December 18th [1912]. It is certain that they had not met during 'Abdu'l-Bahá's previous visit to England. A letter from 'Abdu'l-Bahá to Edward Browne, preserved in Cambridge University Library, provides the definite evidence. Zarqani's Diary mentions only two meetings during 'Abdu'l-Bahá's second visit to London, whereas Lady Blomfield writes: 'Professor Edward Granville Browne, who had written much concerning the Bábís and the Bahá'ís, came from time to time, speaking in Persian with the Master, Who was delighted to see him, and talked over many things, especially the momentous occasion when that intrepid Cambridge Orientalist succeeded in obtaining permission to enter the presence of Bahá'u'lláh.' (H.M. Balyuzi, Abdu'l-Baha - The Centre of the Covenant, p. 346)
... Mirza Mahmud-i-Zarqani -- 'Abdu'l-Bahá's secretary in the course of His travels, and the chronicler of those memorable years in the West -- has recorded, Browne during his first visit wished to broach the subject of his writings in the past and offer apologies, but 'Abdu'l-Bahá drew away from this topic and said: 'Let us talk of other matters which would be conducive to amity' (H. M. Balyuzi, Edward Granville Browne and The Baha'i Faith, p. 96)
