" 4. — A description of the disease as it affects domestic 

 animals, with illustrative cases. 



" 5. — Inoculation and feeding experiments to show the 

 communicability of the disease from affected to healthy animals. 



" 6. — Treatments of the disease, prophylactic and curative." 



The "Report" is illustrated with six plates (in addition to 

 temperatui'e charts) as follows : — - 



Plates I. and II. are devoted to the " Tsetse-Fly." 

 Plate I. contains the following coloured figures : — 



1. — Fly at rest (natural size). 4. — Fly at rest (x 2). 



2. — Larva (natural size). 5. — Fly with expanded wings ( X 2) . 



3. — Puparium (natural size). G. — Fly before feeding (x 2), 



7.— Fly after feeding (x 2). 



Plate II. is devoted to reproductions from photographs, as 

 follows : — 



1, 2. — Fly with expanded wings. 5. — Fly during parturition. 



3.— Fly at rest. 6.— Pupa. 



4.— Fly pregnant with larva. 7, 8. — Flies in various positions. 



As has already been remarked in the systematic portion of 

 this work (p. 89), the photographs appear to have been taken 

 from specimens of Glossina palUdipes, Austen, while the coloured 

 figures seem to represent Gl. morsitans, Westw. : the apparent 

 discrepancy may be due to minor inaccuracies in the coloured 

 figures. 



Plate III. shows haematozoa in the blood of the dog, horse, 

 and cow, " all magnified 1,000 times." 



Plate IV. — " Horse suffering from Fly Disease or Nagana." 

 Plate V. — " Donkey suffering from Fly Disease or Nagana." 

 Plate VI. — " Dog suffering from Fly Disease or Nagana."
