THE UNCLASSIFIED FEVERS OF THE TROPICS 



NON-MALARIAL QUARTAN FEVER. 



This fever, described by Castellani, is characterized by having a 

 quartan periodicity and no malarial parasites in the blood, and 

 quinine given in massive doses does not influence the course, which 

 is prolonged, lasting several months.

ANEMIC LOW FEVER. 



In young European and native women aged sixteen to twenty- 

 two years there is a persistent low fever lasting for several months, 

 reaching above 99-4° F. in the afternoon and associated with a certain 

 degree of anaemia, which is met with at times. The patient may 

 become extremely nervous and hysterical. This temperature may 

 be due to the degree of chloranaemia, and has nothing to do with 

 hysterical fever of certain authors, as it disappears on the angemia 

 being treated. 



VESICULAR FEVER. 



Definition. — febrile disorder associated with acute pain in 

 some region of the body, followed by the appearance of a vesicular 

 eruption which becomes general. 



Remarks. — ^This is a fever which at its commencement resembles 

 an attack of chicken-pox, and when it is fully developed closely 

 resembles modified smallpox. We have seen several such cases in 

 Ceylon during the last ten years. 



iEtiology. — ^The causation is unknown. 



Symptomatology.— At no stage of the illness is the patient severely 

 ill, but the commencement is ushered in with sometimes pain in 

 some part of the body, followed in a day by a rise of temperature 

 to about 101° F. and a quick pulse. The eruption may appear at 

 first in the region of the pain, or may be general from the com- 

 mencement, which, however, is not relieved, and may, on the con- 

 trary, have extended to other regions of the body. The pain 

 gradually disappears, a scattered general eruption of vesicles appears, 

 and the temperature becomes normal, while the patient feels better. 

 The vesicles are discrete, dome-hke, or flattened; later, a few may
