Bos taurus. In the ealfs foetus in the proximal portion of the 
cervical sympathicus a few small oval or roundish ganglion cells 
could be seen, in the middle portion, at a few places 10—12 cells 
consecutively and in the distal portion, beside numerous little groups 
consisting sometimes of but a few cells, a large elongated ganglion, 
consisting of over 100 cells arranged principally in two rows, while 
a few cells also lay outside (fig. 4). In seetions of 1.5 em. 8—10 
small ganglia may be met with. The cells have a maximum size

of 30 uw, have no capsule, or only an undeveloped one, though in- 
dications of one can sometimes be seen. On the other hand, two or 
more cells consecutively are frequently surrounded by connecting 
tissue, so that the impression is conveyed as if they lie in a com- 
mon capsule. 
Of an old cow only the distal third portion of the cervical sym- 
pathicus could be examined. In this I found only two ganglia, one 
peripherally of 25 to 30 cells, and a more central one consisting of 
10 cells. In the thoracal portion an elongated oval peripheral ganglion 
appeared to be present in the part between the 3'¢ and 4" segments 
containing 45 cells, and in the last portion (12' and 13% segments) 
a ganglion lying more centrally with + 60 cells. In the pars lum- 
balis many peripheral ganglion cells could be seen and central 
oval-shaped complexes of them, where, however, the cells were less 
numerous and very sparse. Capsule cells were not visible at all, or
