GRAFTING RECORD 



Another page of our older record 

 books, this one also dealing with graft- 

 ing. It mil be seen that the records of 

 different years are associated, and it 

 will be obvious that the records were 

 intended for our own eye, to supple- 

 ment the records of memory. When 

 thousands of experiments are being 

 performed simultaneously, it is impera- 

 tive that the recording should be done 

 with the least possible loss of time.
