Determination and Analysis of Recurrent Groups

Abstract

23, 1953, in the collections during 1954-56. These data were used as another estimate of survival. 5. Revision of the measurements of density was also made possible by the field work of 195456. The adjusted counts were revised and then compared with estimates made by the modified index method. 6. Some long-range records of the growth of greatest head width are compared with average growth curves predicted statistically; however, additional observed data are needed before an evaluation of the average curve can be made.
