the animal remained quite healthy. On the other hand, 

 flies which had fed for a short time on a dog affected 

 with fly disease were allowed to bite another dog on 

 November 21st, 23rd, 25th and 29th, the effect being- 

 that on December 5th hematozoa were found in its blood. 

 In order to show that neither food nor water is the 

 channel by which the disease is conveyed, two healthy 

 horses, provided with network nosebags, were taken into 

 the fly country from about 10 A. M. to -1 P. M. on Sep- 

 tember 19th, 24th, and 29th, but were not allowed to 

 graze or drink. Many flies settled on them and they 

 both contracted the disease, one on October 4th, and the 

 other about October 28th. Another experiment was 

 made by bringing to Ubombo tsetse flies caught in the 

 low country and allowing them to bite a healthy horse ; 

 129 flies were used in this way in ten days, from Nov- 

 ember 22d to December 14th, the horse fell ill on Dec- 

 ember 15th and the hematozoa were found in its blood. 

 The source from which the fly obtains the hematozoa still 

 remains to be discovered. — Lancet.

Dr. Muller of Vienna has described certain particles 

 found in the blood under the name of haemokonia (blood- 

 dust). They resemble fat-globules, and the larg-est are 

 1-25000 of an inch in diameter. The}^ are motile and are 

 unaffected bv osmic acid.
