He presents a somewhat emaciated appearance, although his appetite had always continued good, and certainly since his admission into hospital the man has gladly availed himself of the most liberal scale of diet allowed. This is not surprising when the amount of fibro- albuminous matter which is con- Extremo extent of infection. stantly being drained from his system, as evidenced by the state of the urinary secretion, is taken into consideration ; but when to this is added the fact that no matter at what portion of his body the cir- culation is tapped with the point of a needle, numerous active, well-developed Hsematozoa are invariably ob- tained : on one occasion I obtained as many as twelve of these creatures on a single slide. As the drop of blood from which this slide had been prepared sufficed for the preparation of two or three other slides (which, however, between them did not contain more than half a dozen Tilariae), the number infesting his whole body may be imagined. A rough calculation may very readily be made; the weight of the man is 1001b; if the Approximate number „ ?f *?®^tozoa present amount ot blood be taken as being on the average ‘ not less than one- tcntli of the weight of the body’ (Huxley), and it is assumed that each drop, or grain rather, contains, say, two Hmmatozoa, it would be but a reasonable estimate to set down the number as 140,000 ! It must, however, be borne in mind, that the Hmmatozoa may be more or less localised to the capillaries and smaller vessels, which
