154 QUARTERLY CHRONICLE. 
cean, illustrated by a very clear drawing of the whole animal, 
is contained in this paper. 
Archiv fur Mikroskopische Anatomie. April, 1866.—Ano- 
ther number of Professor Schultze’s excellent journal has 
appeared during the quarter, and contains some valuable 
papers. It is much to be hoped that the present crisis in 
Germany may not in any way retard or prevent the appear- 
ance of another in due course. The papers are as follows: 
1. “ The Intimate Structure of the Spinning Organs of 
Epeira,’ by Hermann Oeffinger.—The author distinguishes 
and figures five sorts of glands in these spiders, as follows :— 
1. Glandule pyriformes; 2. Glandule cylindrice; 3. Glan- 
dule ampullaceze ; 4. Glandule aggregate; 5. Glandule tu- 
berosee. Particular attention is devoted by the author to the 
histological characters of these glandules, and their deport- 
ment with different reagents, such as caustic potash, acetic 
acid, and hyperosmic acid. 
2. “ Researches on the Sympathetic Cord,” by L. G. Cour- 
voisier.—This is an extensive essay, illustrated by two plates. 
The author gives the following statement of results at the end 
of his paper: 
(1) The sympathetic cells of the Vertebrata are connected 
either merely at one pole (‘“‘ Holopol’’), as in the frog, or at 
more—two, for instance—as in other Vertebrata; always 
with two fibres, of which one (‘the straight”), after loss or 
diminution of its fatty sheath, penetrates straight through 
the cell-substance, and ends in the nucleus, whilst the other 
(‘the spiral”) places itself in connection with the nucleolus, 
by means of a network of fibres (Fadennetz). In other cases 
(Hemipolen) fibres (commissural filaments) arise from the 
network which connect these cells with other sympathetic 
cells. 
(2) Each commissural ramus extends from cerebro-spinal 
bundles, which hasten to the sympathetic nerve and to the 
sympathetic fibres of different ganglia which pass from 
above to below, diminished in number in the spinal nerves, 
and occupying a central position, but with increased numbers 
peripherally. 
(3) The “straight fibres” of the sympathetic cells are 
cerebro-spinal, that is to say, they give origin to the cells of 
the spinal-cord of the spimal and brain nerve-ganglia, and 
enter into sympathetic cells. The “spiral fibres” are as good 
as the genuine sympathetic “ commissural filaments ” con- 
nected with them by their origin, and proceed from the cells 
of the sympathetic, either to the visceral portions of the
