small additional bay or central spot about the middle of the anterior third of the body. 

 The column of cell nuclei is coarsely granulai- and reaches right to the caudal end. 

 No annulations of the cuticle have been noted. Tlie ))arasites were numerous in the 

 blood, two being not unconnnon in one thin film, low power field (oc. 1 ; obj. 4 Leitz), 

 while as many as three may occur. 



I found two, presumably parent worms, in the abdominal cavity and sent them to 

 Dr. Leiper at the London School of Tropical Medicine. 



Parasites 



A considerable number of intestinal worms has been collected from cattle, sheep, 

 goats and other animals in the Sudan. Some of the material was sent to Professor Looss, 

 some to Dr. Leiper. 



Acid-fast Bacilli in thk Lung of a Camkl*

In the Sudan, human tuberculosis is an extremely frequent pathological condition, while 

 the same disease occurring in mammals cannot be considered a common one. Dogs and 

 capti%-e monkeys seem to be more susceptible to it in the Sudan than any other animals. 

 A short time ago Captain A. G. Cummins, R.A.M.C., sent to the laboratories a lung which 

 he had removed from a camel that had died in Kordofan. 



The gross macroscopical lesions present were as follows : ^Scattered throughout 

 the surface of the lung substance were numerous grey fibrotic-looking masses about the 

 size of millet seeds. On palpation, these were firm in consistence, and distinctly 

 Macroscopic raised above the surrounding lung tissue. At the base of the lung there were two or 

 lesions three large caseous-looking areas measuring about an inch in diameter and sharply 



demarcated from the surrounding tissue. On incising these caseous-looking masses they 

 were found to be quite firm and fibrous in consistence. Most of the pleura was adherent 

 but did not show the presence of any nodules on its visceral layer. Various incisions were 

 made through different parts of the lung substance, but in no case were cavities detected, 

 nor was there any marked enlargement of the bronchial lymphatic glands. 



For the purpose of microscopical examinations, sections were made through the 

 diseased parts of the lung, fixed, and stained by Van Gieson's and Ziehl-Nielsen's methods. 



In sections stained by the former method, and examined microscopically, it was 

 at once apparent that the lesions represented a type of miliary tuberculosis in whicli 

 reparativ. . - in the form of a, fibrosis were present.
