    then, in order to complete our mental survey of the path of a stimulus wave through such a nervous arc as is called into play in one of the higher animals during the perform- ance of a ^reflex ac- tion,’ it only remains to consider the modes of connection exist- ing between the several cells of sensory groups and of motor groups, together with the kinds of communica- tion existing between these two orders of nerve units. 4. Between the contiguous cells of a motor and perhaps also of a sensory group, union is brought about in some cases by means o 1 .f * 1 Nerve Cells connected by inter- 01 a snort simple cellular processes (6, 6), and giving origin to outgo- iutCTCcllulciV process fibres (c, c, c, and a). 4. Multipolar cell contain- , ’ ing much pigment around nucleus. Diagrammatic. such as we see repre- (Vogt.) sented in figs. 1 and 14. But whether this is the most frequent means of union, or whether, in the majority of cases, especially amongst sensory groups, it is not rather by the inosculation of the rootlets of ramifying processes (with the possible interme- diation of the neuroglia) we cannot at present say. There is reason to believe that both modes of union may exist. 5. The cells of a sensory group are united with the
