382 _ Major W. H. Horrocks. Goats as a [ July, 
the sera on the JZ. melitensis. The results he obtained are given in Part VIII; 
it will be seen that, out of 161 goats examined, 84 gave a reaction, corre- 
sponding to a percentage of 52 probably infected with Mediterranean Fever. 
I then obtained samples of milk from some of the apparently infected 
animals, and proceeded to plate them on litmus-nutrose-agar. The following 
results have been obtained up to the present time :— 
ELeamination of the Goats supplying Milk to Forrest Hospital. 
I visited this herd, which assembles outside the hospital gate every 
morning, and selected Goats Nos. 38, 48, 37, and 43 from Captain Kennedy’s 
list. 
Goat No. 38.—The milk from this animal was centrifugalised, and the 
deposit plated on July 4, 5, 6, 7, 8, and 10, but, up to the present, the 
M. melitensis has not been isolated. 
Goat No. 48.—The milk was examined on the same dates as Goat No. 38, 
but, so far,'the WZ. melitensis has not been isolated. 
Goat No. 37.—The milk of this animal was taken on July 4, and 2 cc. 
centrifugalised ; the deposit was then plated. After four days’ incubation 
every plate was found densely crowded with small colonies of the 
M. melitensis ; the colonies were so numerous that it was impossible to make 
an accurate count. The colonies were fished and planted on agar, the growths 
resulting responded to all the tests characteristic of the I. melitensis. 
On July 5 and 6 the milk was again plated, and similar results were 
obtained. 
As this goat was in full milk, there cannot be any doubt that the 
M. melitensis was being excreted in large numbers. A pint of the milk was 
then collected, and Dr. Zammit very kindly made a chemical examination of 
the sample. The result given below shows that the milk was of good quality.

Goat No. 43.—The milk of this goat was examined on July 4, 5, 6, 7, 8, 9, 
and 10, but, up to the present, the JL melitensis has not been isolated. 
A reference to Captain Kennedy’s list shows that, while Goat No. 37 
reacted in a dilution of 1 to 60, Goats Nos. 38, 48, and 43 only reacted in a 
dilution of 1 to 20, and were probably in an early stage of the disease.
