The first of the four thousand six hundred fifty-six cases of yellow fever recorded in Jacksonville in the summer and fall of 1888 was that of R. D. McCormick who had lately come from Tampa and who was reported ill on July 28. Though this caused some alarm, the assurance of the Board of Health that it was a sporadic case seemed to calm all fears.
