Page 29 - Browning,4 does not think that the immunisation and subsequent inoculation advocated by Laveran constitutes a sufficient basis, but it is clear that much more work will have to be done before the precise value of this procedure is ascertained. It would seem that wherever possible it should be supplemented by cultural experiments, a means of diagnosis strongly upheld by Bruce as a result of recent work on nagana and T. dimorphou. 1 Cazalbou, L.

From the third to the eleventh segment, the body is thickly covered with minute recurved spines of brownish chitin (darker in the case of larvae ready to leave the host), usually arranged in transverse series or groups of two or more, which can be seen to form more or less distinct, undulating or irregular, transverse rows. These spines will...

Page 389 - Boport as to the suspended matter carried by the White Nile — viz., that this is found in appreciable amount during the entire year, and that the water is never quite clear. As before, the lowest proportion was found in the latter part of September and the first half of October. This is obviously accounted for by the fact that during the period of flood of the Blue Nile the flow of the White Nile is impeded to such an extent that, south of Khartoum, the river is converted into an immense lake....

Mandibles (Plate 5, Fig. 78) black, slightly serrated and with two tufts of curved hairs at the base. First thoracic segment anteriorly brown. Laterally placed on the second and third thoracic segments are brown comb-like marks with the four teeth pointing backwards. On the anterior portion of each abdominal segment — with the exception of the eighth — are two brown annuli, or rings, encircling...
