Horned cattle .... 157,598,521 



Sheep 382,703,015 



Goats 15,704,911 



Hogs 81,091,331 



Buffaloes 89,281 



Keindeer 90,567

The ouly species for which an estimate had been made of the 

 total number in the world was the sheep. Mr. Robert P. Porter 

 had made such an estimate, which, though varying from the official 

 data in many of the above countries, afforded a basis for extend- 

 ing the figures already obtained to the remaining portions of the 

 globe, and according to which the ovine population of the earth 

 would reach 577,703,015. Using this result as a basis, a very 

 rough estimate of the number of each of the remaining species 

 in regions not already covered by actual enumerations would 

 place the aggregate number of all the species named throughout 

 the world at a little upward of one billion head and their distri- 

 bution would then be about as follows : 



Horses 70,770,597 



Cattle 230,397,781 



Sheep 577,703,015 



Hogs 100,000,000 



All other animals .... 32,391,247 



1,017,322,040 



Reasons were, however, given for regarding this estimate con- 

 siderably too low, both as to the number of sheep, upon which it 

 is based, and also in the aggregate, and the speaker thought that 

 the latter would probably reach nearly a billion and a half. 



Comparisons were then made with the human population. Ac- 

 cording to a recent work by Baron Kolb the population of the 27 

 countries, from which reports were obtained, amounted, in 1878, to 

 300,100,000. This would give, upon an average, in all these coun- 

 tries, 130 horses, 430 cattle, 1,040 sheep, 224 hogs, and 29 of all 

 the remaining animals taken together, to each 1,000 human beings, 

 and for all these species combined, 1,887 animals to each 1,000 of 

 population.
