The concentration of mature morula and dispersed vesicular cells as a function of position in the tunic. Field 1 is at the epidermis and field 5 is at the external periphery of the tunic. Values reported are the mean concentrations for a sample of 5 animals with six replicate counts per animal. time after injection gives a significant F ratio (P < ). There is an increase in number of hyaline amoebocytes with carbon after injection with a maximum reached at 18 hours (Fig. 8). Mean comparisons of per cent of cells with carbon show that by 6 hours there are greater numbers of cells with particles than there are in controls, and this significantly higher number of cells with carbon is main- tained over the 48 hour study period. The nature of the particles in the hyaline amoebocytes of the control studies is not known. However, hyaline amoebocytes often display some particulate or granular inclusions and hyaline amoebocytes which contained such particles were counted in the baseline controls to obviate misinterpretation in the phagocytosis studies. IX. Tunic injury Analyses of variance of the concentration of the four blood cell types in tunic at the site of injury as a function of day after injury reveal significant increases.
