Student report on the heredity of longevity, example 2

Actual Record of Longevity in Family O = Female, [square] = Male sons and daughters [art] = died in infancy [art art ] = 80 years or over [diagram] Prof C.N. Hargitt Syracuse Uni. The members of the last line are all living (one member of which is my mother) with the exception of those marked 1 and 2 - This chart might also prove the tendency to have larger families, which however is dying out there being but seven children in the last seven families - I have traced just the line which comes directly down to my own family and have used our family records for my work. It is entirely authentic.
