. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. 60 F. G. WALTON SMITH. . Similar disc to that of Figure 4 after period of \() days rotation at 6(1 p. Age of barnacles before rotation is marked on each sector. neither continued development nor remained attached at diameters beyond 16 inches, corresponding to a current of knots (Table III). Within Sector VI, however, with barnacles originally 16 days old, a small number remained attached even at the outer edge of the disc, where the water flow approximated knots. On the in- tervening sectors with barnacles of intermediate ages, the current velocities bring- ing about complete loss of attachment showed values between these extremes. I'robably because of further attachments on the stationary control, the density of attachments on all sectors of the rotated disc was below that of the control. The etlects upon growth rate are illustrated by the observations in Table IV. On Sector I. within a -1 inch diameter, equivalent to knot, barnacles reached a maximum width of X mm., compared with growth on the control of only 7 mm. At knots, growth was reduced to onl 3 mm. and at knots, no barnacles re-.
