of the disease. Those who have recovered are usually incapacitated for 
hard work especially during warm weather. The writers themselves 
have never seen a person suffering from milksickness, but conversations 
and correspondence with doctors who have treated cases, and with per¬ 
sons who have recovered from an attack, indicates that the preceding 
account of symptoms describes the disease. 
Mortality in Trembles or Milksickness 
No data are available from which even an approximation of the 
fatalities among domestic animals can he made. One writer has esti¬ 
mated that 5,000 animals have died from the disease in a certain area 
in northern Ohio. The outbreak near Minooka, Ill., which occasioned 
the investigations of Crawford (1908), previously referred to, resulted 
in the death of about fifty cattle. Mr. H. E. Crawford, Shooting Creek, 
N. C., reports the loss of hundreds of dollars worth of horses, cattle, 
sheep, and hogs, and that in almost every case affected animals suc¬ 
cumbed, f In a flock of sheep which came under the observation of 
Mr. George Evans, Sheep Eield Specialist at this Station, seven animals 
in a flock of eight died. In our feeding experiments with sheep, only 
one individual characteristically affected recovered among a total of 
thirty-one animals. In the succeeding year this animal was again used 
in feeding experiments and contracted the disease and died. All accounts 
which have come to hand, both published and verbal, indicate that rela¬ 
tively few animals recover from a prolonged attack of trembles. 
The data on the mortality in man from milksickness are by no means 
complete and considerable differences of opinion are found to exist in 
published reports. Coleman (1822) reports the loss of “about one case 
in twenty or thirty,” and Collins (1902) “about 40 per cent of my 
cases.” Dr. J. E. Wilson, Canton, N. C., informs us that he has treated 
many cases without the loss of one. 
Jordan and Harris (1909) have prepared a tabulation of all pub¬ 
lished reports in which the number of cases and deaths is specifically 
stated. This tabulation will emphasize the variation which has been 
mentioned and will give at least an approximation of the average mor¬ 
tality. It will, therefore, be quoted in toto, and to it will be added the 
record of fifty-six cases and eleven deaths which either came under the 
observation of Jordan and Harris or were reported to them during 
their investigation of this disease, and of two deaths at Losantville, 
Indiana, in 1916.* *
