AMERICAN MEMS.
A San Francisco correspondent states that Charles Weightman (the man-fish) is dying of consumption in St. Mary's Hospital.
The Lorgnette (Melbourne) - Friday 8th July, 1887.
Charles Weightman (the man-fish), died at St. Mary's Hospital, San Francisco, on the 3rd May. His last days were made comfortable by Al. Hayman, of the Baldwin Theatre and formerly of Australia. The Company of the Baldwin Theatre) purchased a burial lot and had a neat headstone placed thereon. Al. Hayman generously volunteered to assume the entire obligation. The deceased's wife, (better known as Miss Kate Douglass), is now with Bland Holt's company in Sydney.
Hope this helps a little, cheers, Nipper.
