to modify his views, but have rather confirmed and extended 
them. Dr. Beale remarks upon the improbability of the 
structure of the mammalian liver being so entirely different 
from that of invertebrata or reptiles, as the views of Hering 
would imply. 
The figures given represent sections from a human liver 
somewhat altered by disease (¢.e. in a state of venous con- 
gestion from obstructive disease of the heart). The bile ducts 
were injected with Prussian blue solution, and the result was, 
in Beale’s opinion, to inject fully and normally the “ cell- 
containing network ” of bile capillaries. A tubular network 
is seen containing the blue injection, and also liver cells, 
scattered and displaced, lying within the tubes. Some figures 
show this injected network to be continuous with the inter- 
lobular bile ducts. The appearances are, on the whole, the 
same as those shown in former figures published by the author 
(as in the ‘ Philosophical Transactions,’ for 1856), but are 
clearer and more complete. 
Dr. Beale admits that no compromise as regards the question 
is possible; that if the view now generally entertained in 
Germany be true, his conclusions are false; but he contends 
that while his opponents cannot account for the facts demon- 
strated by him, he can explain their (¢.e. Hering’s) results by 
the inadequacy of their injection, which, by being introduced 
under very slight pressure, had only made its way into the 
parrow spaces between the cells and in the intervals between 
these and the walls of the tube; having, in fact, taken the 
course pursued by the bile during life. The appearances thus 
produced are seen here and there in all injected livers, but 
more uniformly in the liver of the rabbit than in most 
vertebrated animals. What Hering calls gall-capillaries are 
then simply spaces between the cells. 
We may remark that as several histologists in England have 
now had the opportunity of examining Hering’s preparations, 
there ought to be no difficulty in seeing precisely where the 
point in dispute lies; but Dr. Beale’s figures are not minute 
or precise enough to give any information as to the special 
points on which Hering relies, namely, the position of in- 
dividual cells in relation to one another. 
Nervous System. Braim.—The most important and original 
article in the last part of Stricker’s ‘ Manual of Histology,’ 
and perhaps in the whole work, is Meynert’s essay on the 
brain. It is illustrated with thirty-two figures (mostly original, 
a few from Lockhart Clarke), which are marvels of beauty and 
clearness in wood engraving. A considerable part of the 
paper is occupied with a topographical account of the dis-
