symptoms in the interval between two paroxysms, the 

 temperature becoming normal or subnormal. In 

 remittent fever there is only an amelioration of the 

 symptoms in the intervals. Hemorrhagic malarial 

 is a grave form of malarial intoxication in which 

 the height of the paroxysm is characterized by head- 

 ache, severe pain in the back, nausea, vomiting, 

 decided jaundice, and hemorrhages from various 

 mucous surfaces, particularly from the kidneys. In 

 certain localities in which the malarial organisms are 

 exceedingly numerous or intensely virulent the attack 

 ays a pernicious tendency. Of this type there may 

 be a cerebral form, characterized either by delirium 

 : and excitement, or by coma and depression ; a thoracic 

 form, in which the respiration is accelerated and there 

 is an urgent sense of the need of air ; a gastro-intestinal 

 form, attended with nausea, vomiting, jaundice, and 

 diarrhea ; or an asthenic or algid form, in which there 

 is a condition of marked debility and a striking cold- 

 ness of the surface and of the breath. To the irregular 

 manifestations of malarial poisoning, sometimes acute, 

 but more frequently subacute or chronic, which do not 

 at any time present the classical association of chill, 

 fever and sweat, the designation of " dumb ague" is 

 given. The enlargement of the spleen in a case of 

 chronic malaria or of malarial cachexia is sometimes 

 designated "ague cake." M. Hematuria, the pre-
