Historical information

Four items about a bronze medallion of Edith Mary Howitt:
1/ Photocopied letter from Alex Turnbull, dated 15/10/1913 to Mr. A.W. Grieg who on reading an article by Mary E.B. Howitt, is wanting to know which Mary Howitt is represented on the bronze medallion in his possession, executed by T. Woolner dated 1853 Melbourne (2 pages).
2/ Handwritten photocopied letter to Mr. Greig from Mary G.B. Howitt dated 09/01/1914 confirming that Mr. Turnbull’s medallion is indeed of Edith Mary Howitt (2 pages).
3/ Photo copied typed correspondence from Helen Tyzack dated 08/08/1980, from the Australian National Gallery, Canberra, requesting information about Thomas Woolner’s medallions either bronze or plaster. The La Trobe library have been unable to assist, and she was wondering if the Royal Historical Society had any further information (1 page).
4/ Photocopied reply to Helen Tyzack dated 10/09/1980 which, after an exhaustive search, brings several letters to the fore, correctly identifying the medallion as being Miss Edith Mary Howitt, from H.N. Warren, director.
