Table of the Divisions of the Tertiary Period. 



Definitions. 



Characteristics. 



HISTORIC in which the events are 

 recorded in history. 



Modern Types of Mankind. Man the 

 master of the World. 



PREHISTORIC in which man has mul- 

 tiplied exceedingly. Domesticated 

 plants and animals. Wild Eutheria 

 oi living species with the exception 

 of Irish Elk. 



Modern Types of Mankind. Culti- 

 vated fruit and cereals. Domestic 

 animals. Wild Eutheria of living 

 species. 



PLEISTOCENE in which living species 

 of Eutheria are more abundant than 

 the extinct species. Man appears. 



Extinct Types of Mankind. Modern 

 Type. Living Eutherian species 

 dominant at close of period. 



PLEIOCENE in which living species 

 appear in an Eutherian fauna mainly 

 of extinct species. 



Living Eutherian species present. 

 Extinct species dominant. Extinct 

 genera well represented. 



MEIOCENE in which the alliance be- 

 tween living and extinct Eutheria is 

 more close than in the preceding 

 stage. 



No living Eutherian species. Living 

 Eutherian genera appear. Extinct 

 genera dominant. 



OLIGOCENE in which the alliance be- 

 tween extinct and living Eutheria is 

 more close than in the Eocene. 



No living Eutherian genera. Living 

 families and orders. Extinct 

 families and orders numerous. 



EOCENE in which the Eutheria are re- 

 presented by living as well as by 

 extinct families and orders. 



No living Eutherian genera. Living 

 families and orders. Extinct 

 families and orders dominant. 



This classification meets the present demands of science, and is 

 sufficiently wide to include all branches of the study of Man, as well 

 as of Nature. Had the Manchester Museum been arranged on purely 

 natural history lines, like that of the British Museum, there would have 

 been no place for Egypt, or for those collections which will ultimately 

 form centres for the study of anthropology, ethnology, and prehistory. 

 It is of a new type, ready for use in the new England that is now in 

 the making. It is unnecessary to deal with its value in strengthening 

 the natural history teaching in the University. It is sufficient to say 

 that without it the present high standard could not have been achieved. 

 Outside the University it has helped to educate the general public 

 by free demonstrations, addresses and lectures, given by the staff of the 

 Museum and University. These began in the old Natural History
