AND ITS RELATION TO ANIMAL LIFE IQ 



should be of a bright red colour when drawn 

 from the animal ; this blood clots quickly, being 

 of a uniform bright red right through the clot. 



Now, if the blood were always of one con- 

 stant and normal colour, we should not hear 

 of many diseases ; but, unfortunately for the 

 animal world, there is very great variation in 

 the colour of the blood, an indication of 

 variation in its chemical composition. 



In the large number of animals that I have 

 examined in South Africa the blood has more 

 often than not been of a much darker or 

 lighter colour than normal blood, when taken 

 in a similar way in each case, namely, from the 

 throat ; yet these animals were not showing 

 any signs of disease, and to the ordinary eye 

 were in normal health. 



In many cases they had a very dark blood 

 only partially coaguable, proving there is 

 considerable variation in the quality of the 

 blood of ordinary animals, which is easily 

 explained and to be expected when one recog- 

 nizes the great variation there is in the quality 

 of the food eaten. 



I have also noticed that whatever the 

 disease from which an animal was suffering,
