ANIMAL TBYl'ANOSOMIASES IN THE ANGLO-EGYPTIAN SUDAN 



51 



This table is prepared in the same way as the preceding tables, and in it the close 

 resemblance of the six series of measurements quoted here is very striking, when it is 

 remembered that the strains which they represent have been obtained from different 

 sources. 



Two charts are here given showing the distribution by percentages in respect to 

 length of this trypanosome ; one was prepared by Colonel Sir David Bruce in London, and 

 the second prepared in Khartoum.

These two charts are very similar, and, as mentioned above, make a striking contrast 

 with the charts showing the curves of Type 1 and the T. brucei of Uganda.
