The third ox is that shown on pa<;e IKi, Fig. (JM. 'Die lilooil was taken at Khartoum 

 on .■>(Mh Oetoher, ami as iriaiiy as two trypanosonies were foiiml in some (ields. The animal 

 was kept ami well fed. (hi Itli NovenibiT fresh luid stiiined blood films were exiimined, but 

 no parasites eouhl 1" di iiionstrated. Thereafter, though the Mood wiis centrifuged and 

 examined, und though the animal was sulijeeted to four days' partial starvation, 

 trypanosonies were not again found. Eventmdiy, as the owner wished to slaughter the ox, it 

 was exehiinged for o.x No. 4, wliieh was exaniine<l on "JMrd Novemlur, when a considerable 

 iiiiiiil);'r of trypanosonies were found, as many as six per eover-ghiss preparation being 

 jireseut. This ox lontiniK d to .slmu the parasites in its blood, and grailiially beeanie 

 thinner and weaker. 



On 8rd December it was fdiiml to lie verv weak with marked aiia-mia and driliMing 

 urini'. Tile urine and fa'ces were examineil U>v KIikhI. liiit none was present. The fwces 

 were slightly tarry in eoiisistcnee, ami this and their colour suggestecl the examination. 



l)n 4tli Deeeiiilier the ox was found to lie in extremis. Trypanosonies were slightly 

 iiKU'e numerous in the blood, and as it was feared the animal might die during the night, it 

 was slaughtereil. and an aiitopsv performed imineiliiitidy. 

 Posi-mortcni The principal points noted were ; — 



'"^^ (ii) The extelisivi' sulieutaneous, gidatillous. ami pale yellow exudation. Nearly every 



part of the snlieutaneons connective tissue was ill an nMlematous, watery condition, wlii(di 

 was most iiiarkeil where the skin was loose, i.e., in the dewlap, lieliind the shouhlcrs, ami in 

 front (jf the haiineh. 



(/') Till' preseiici' of enlarged purple lucmorrhagic glands ahout the root of the neck. 



((•) The gri'at and general enlargement of the mesenteric glands, which were also, 

 though to a less extent, hwniorrhagic in nature. 



{(/) The presence of a certain amount of chronic meningitis atVecting the pia arachiioiil, 

 the pia being somewhat adherent to the surface of the convolutions. There was little 

 thickening of the iiieiiiliranes, and no a[)pearance of encephalitis. Indeed, the brain 

 appeared markedly anajniic. The stomarli, which was distended witii food, presented no 

 ulcerative condition, but contained "bots'of a dirt'ereiit kind to any I have seen in the 

 Sudan. Till' intestinal tract was normal. There was nothing special to note with regard to 

 the siileeii and liver, wliiili were neither conge.sted nor enlarged. The heart's blood showed 

 trypanosonies. Fluid from the lateral ventricles of iIk brain and from the eerebro-spiual 

 tlnid showed nothing in the way of trypanosome infection. Jiile taken with aseptic 

 precautions from the gall bladder contained a short stout bacillus in considerable numbers, 

 but no Hagelhiteil parasites. 



The cow at Melut was picked out by the natives as being ill. The blood was 

 collected in tubes containing citrate of soda solution. Such blood showed trypanosonies, 

 though these were only found after some scan hing. 



The Abyssinian cow which aborted at Taiifikia. and was in a dying condition, also had 

 trypanosonies in its blood, but they wi re not at all numerous. Time iliil not admit of a 

 post-mortem ixamination in this case.
