“…Although no two animals exhibited iden tical quantitative growth, the general growth pattern was similar (table 11). The length of the rabbit nasal bone is highly variable [Latimer and Sawin, 1962].…”

Two radiopaque implants were inserted into each left and right nasal bone in 5 female rabbits. Ventrodorsal cephalometric radiographs were then taken in a specially designed head-holder at 6 and 16 weeks of age. From these radiographs separate tracings were made on matte acetate paper of the left and right nasal bone regions including the radiopaque implants. Since the implants maintained the same relationship to each other in each nasal bone, they served as stable reference sites. The markers of the 16-week tracing were superposed on the markers of the 6-week tracing. The difference in the two established outlines represented the changes in size and shape in two dimensions that had occurred during the 10-week period. Our purpose was to determine the relative growth activity at several borders. The mean increase was 6.79 mm at the proximal (posterior) border, 6.19 mm at the distal (anterior) border, 2.73 mm at the lateral border, 1.22 mm at the medial border. Thus, growth at the proximal and the distal borders was about the same and about twice that of the lateral border and about 5 times that of the medial border.

Significant sex and strain differences i n correlation of bone, body and skeletal weights show significant localized effects of sex and strain and a combination of both, Individually they seem to lack biological meaning. However, when considered in relation to the ponderal correlations, of which they are a part, they fall into place at the distal ends of a graded linear correlation series, both within and between limbs; and similarly between mandible and sacrum, respectively, with each bone of both limbs. The pattern of these gradients reveals a linear decline in correlation of bones with distance (rule of neighborhood, Karl Pearson) in most cases, but the exceptions are such as can be related to the functions in which they cooperate. In this way they demonstrate at least two major unifying genetic influences. One associates sex and strain with locomotion and the other with the incipient upright investigative posture of the Lagomorphs (including the rabbit). The expected effect of sex on the pelvis is apparently not expressed by these ponderal measurements. The manner in which this correlation approach, based on well established genetic growth differences, converges with the phylogenetic and ontogcnetic concepts of normal and abnormal growth of bone in limbs and cranio-facial development suggests that a combination of correlation and epigenetic analysis would be helpful in establishing a sound genetic background for the newer biomechanic, functional matrix and architectonic approaches.
