In an 1877 testimony to the Cape of Good Hope Commission on Diseases of Sheep and Goats livestock producer J. Webb testified that the appearance of ticks on his farm 8 or 9 years earlier corresponded with an onset of fatal disease in his livestock. Webb reported opening the chest of the victims and discovering the "heart bag" to be full of "water."
