AN EXHIBIT OF A SYSTEM OF MAKING PEDIGREE RECORDS.
Exhibited by Dr. Raymond Pearl,
Biologist of the Maine Agricultural Experiment Station, Orono, Maine.
This exhibit consists of a series of blank record forms designed to illustrate the method of keeping pedigree records which has been in use at the Maine Agricultural Experiment Station for a period of five years, in connection with its work in the experimental study of inheritance in poultry and in various plants. The advantages which have been found by experience to inhere in this system of pedigree record keeping are (a) simplicity; (b) ease of operation; (c) small chance for error in the keeping of large masses of pedigree records; (d) uniformity of the system, such that records of all kinds, in any way pertaining to the work, may be brought together with great ease for consultation or study.
In addition to the record blanks there are exhibited also various marking devices and other apparatus connected with the proper working of the plan.
It should be noted that while the blanks here exhibited are devised particularly for work with poultry and plants, the same system, with slight modifications, may be successfully applied to the keeping of human pedigree records; indeed it is a pleasure to state that the system here exhibited is an outgrowth and development of a scheme for the keeping of pedigree data in general and particularly human pedigree records suggested many years ago by the late Sir Francis Galton.
