Spiders. 1UCGENEKATI0N OF LOST OHGANS. 121 Red Blood Cells. Tli is may be seen in the series of figures 82, 83, 85. At first the cupola and the cavity beneath are large (Figs. 82, 83), but as the tissues that fill the cavity decay and disappear they diminish more and more (Figs. 85, 86), shrinking gradually towards the base of the joint. The tissue of the matrix is only atrophied in part; really, it is in those parts which converge above the cavity of the joint at the summit of the cupola, that is to say, where the amputation has produced a rent, that one observes the regeneration of the fatty tissue. The deep regular cells seen at the junction (Mtx) entirely disappear, and also afterward the part contiguous to the matrix. The red blood cells, after part of them have been regenerated and given birth to the cicatrix, dis- j^t-o pose themselves in different *â ctT1 ⢠parts of the joint. They glide between the fibres of muscles and into the clefts which are formed by their gradual bending. The orifice form- ed after the oper- ation at the sum- mit of the joint between the fragments of the matrix (Fig. 84, O), in spite of the Mt. gradual approximation of the extremities of the ma- trix (Figs. 85, 86, O), re- e* mains open. In the degree that the summit of the cupola sinks the orifice becomes narrower, which, however, does not hinder the blood cells from pen- Fig. 83.
