2. An irregular type, at times intermittent, and at times sub- 

 continuous. 



3. An undulating type. This is very rarely observed. 



Great care should be taken in making the diagnosis of ankylo- 

 stomiasis fever to exclude other conditions — e.g., malaria, Malta 

 fever, kala-azar, trypanosomiasis, etc. There is much diversity 

 of opinion on the origin of this fever. In our experience the fever 

 is not due to the worm itself. It is of bacterial origin, being probably 

 due to infections by intestinal bacteria entering the general circula- 

 tion through the smaU wounds produced in the intestinal mucosa 

 by the worm. The term ' ancylostoma fever ' is, therefore, not 

 quite appropriate. In several cases the fever continues long after 

 the patient has got rid of the ancylostomes by adequate treatment.

Urine. — The urine is copious, pale, and often alkahne, with a 

 specific gravity varying from loio to 1015. Albumen is rarely seen, 

 but there is an increase of indigo-blue and urobihn, and there is 

 albumosuria at times. The excretion of nitrogen is said to be 

 much increased. Lussana believes that there are toxins in the 

 urine which can be separated by the following method: The urine 

 is condensed in a water-bath at 60° to 70° C. to a syrup, and then 

 extracted with absolute alcohol, which is driven off, and the residue 

 dissolved in sterilized water, and injected subcutaneously into 

 rabbits. This is beheved to produce diminution of the red corpuscles, 

 loss of haemoglobin, and poikilocytosis, which speedily disappear on 

 stopping the injections. These findings of Lussana have been 

 confirmed by some and refuted by other observers.
