8. Of the ganglion-cells of the heart. 
The author’s conclusions are quite opposed to those of 
Kolliker, who states that all the cells are wnipolar, and that 
the fibre always passes in a peripheral direction, also that the 
transcurrent fibres of the vagus have no connection with 
these cells. The author, on the contrary, affirms that the 
cells have at least two fibres coming from them, that some of 
the fibres pass towards the heart, and others towards the 
brain. He regards it as very probable that many at least of 
these ganglion-cells are connected with fibres of the vagus. 
Kolliker has also stated (1860) that many apolar cells could 
be seen in the heart, ganglia, and in the bladder. The author 
has been able to demonstrate fibres in connection with so 
many cells which appeared devoid of fibres, that he considers 
himself justified in denying the existence of apolar and uni- 
polar cells altogether. 
Next follow some observations on “ the ganglion-cells and 
nerves of arteries ;” ‘on the connection of the ganglion-cells 
with each other ;”’ and the paper concludes with a description 
of the so-called “capsule” of the ganglion-cell, and a dis- 
cussion on the nature and formation of the connective tissue 
and its corpuscles in the immediate neighbourhood of nerve- 
fibres. 
The paper is illustrated with forty-seven drawings of the 
specimens, magnified from 700 to 1700 linear; and the 
author states that many of the specimens will probably retain 
the appearances he has copied for several months. All the 
preparations have been made in the same manner. An 
outline of the process has been already given in the author’s 
previous communications, but the author is aware that it may 
be some time before the correctness of his conclusions is 
generally admitted, in consequence of the difficulty of pre- 
paring demonstrative specimens.
