increased slowly, but at 11 p.m. the Baboon was still playing 

 languidly. 



The followng morning she was lying down, ^^^th the eyes 

 closed, and unable to rise or move to any extent, although quite 

 conscious. 



At 3 p.m. the animal was very weak, and respiration was 

 slow and stertorous. 



Death occurred at 3.20 p.m. (twenty-seven hours after the bite). 



Before death the skin showed a large livid area over the 

 abdomen. 



In the post-mortem, the most striking points were — 



(i) Haemmorrhagic infiltration occurring subcutaneously in 

 patches, quite remote from the bite. 



(2) Haemmorrhage into the caecum and colon. 



(3) Apparent degenerative changes in the liver (not yet 



studied histologically) . 



(4) Excessive anaemic pallor of most parts. 



Results of Other Experiments. 



In experiments on the effects of Snake Venom on domesti- 

 cated animals, undertaken recently at the Veterinary Research 

 Laboratory, Onderstepoort, Pretoria, I have subjected some 

 twenty-five horses, mules, and sheep to the actual bite of Cobras 

 {Naia flava and nigricollis), Boomslangs, l^nghals, and Puff 

 Adders. 



Amongst the animals bitten by each species of snake, there 

 have been some showing an acute onset of sjmiptoms, ending 

 rapidly in death, some taking a more chronic course, but with 

 a fatal termination, and others ending in recovery. 



In these cases, blood has been taken at intervals, and examined 

 with the following results : — 



(i) No appreciable diminution has ever been seen in the 

 number of red corpuscles, as determined by the 

 haematocrite. 



(2) In no case has any haemoglobin coloration of the plasma 



or serum been observed ante-mortem. 



(3) In a few cases there has been a marked difference in the 



coagulabihty of the blood. 

 Thus in cases of two sheep dying fairly quickly as a result
