MIRACLES OF SCIENCE 



being thus produced. If the divided cell may be 

 thought of as producing severed personalities, then 

 the fused cells certainly suggest a blending of per- 

 sonalities that is no less interesting. The individual 

 that has resulted from the actual fusing of the sub- 

 stance of two individuals, even though he presents 

 only the normal number of physical organs and mem- 

 bers, must assuredly have certain hereditary poten- 

 tialities over and above the average of his fellows, 

 inasmuch as each one of the offspring of the same 

 parents differs somewhat from all its brothers and 

 sisters. 



That giants of extreme size are usually below the 

 average in quality of mind and body, suggests the 

 possibility that such abnormal individuals have re- 

 sulted from the union of two or more ova of divergent 

 tendencies, even of different sexes, representing, 

 therefore, qualities too divergent for harmonious 

 blending. The experimenters of the future will per- 

 haps find the investigation of this question a fertile 

 field. 



NEW HEADS FOR OLD 



The experiments that thus make one individual 

 into two or two individuals into one, find an interest- 

 ing counterpart in experiments of another type which 

 are concerned with the regeneration of lost members. 

 Here the tests are made on adult organisms, but for 

 the most part the creatures experimented upon be- 

 long to low orders. 



It is only creatures of the scale of development of 

 worms, for example, that can be induced to grow new
