in 640. On the second occasion the following was the result:—

fortnight's duration, a relapse, which lasted for several weeks, began. The tem-

symptoms were present.

       The agglutination reaction of the serum with M. Melitensis was tested on
two occasions. On the first occasion, five days after the onset of the initial attack,
a complete reaction in dilution of 1 in 60 was obtained with an emulsion of stock
M. Melitensis. On the second occasion, namely, at the end of the fourth week
