traced most. decidedly the Berlin blue from the interfasci- 
cular spaces into lymphatic tubes, as is represented in Fig. 8. 
Schenk, likewise, maintained such a connection. 
Very interesting and decisive proofs of this connection I 
obtained from preparations of the case of the new-born child 
above mentioned, whose lymphatic trunks contained clumps 
of sebum. Here I found in many parts of the skin smaller 
and larger drops and clumps of sebum contained in the inter- 
fascicular spaces, being either unstained or stained brown 
with the asphalt-benzole. In some places the interfascicular 
spaces were filled with the sebum particles, and we had then 
a good natural injection of the interfascicular spaces. They 
could be easily traced into the lymphatic vessels. 
B.— The Lymphatics of the Adipose Tissue. 
23. The adipose tissue is very richly supplied with lym- 
phatics, and the investigation of these forms one of the. 
important points of this inquiry. Teichmann knew of no 
lymphatics in the fat-tissue, and also G. and F. Hoggan 
deny the existence of such. Neumann mentions in his 
monography above quoted (l.c., p. 25, cap. ILI, fig. 5) that 
the lymphatics form wide meshes which surround the in- 
dividual lobules of the fat tissue, but he did not succeed to 
trace lymphatics between the fat-cells, 7.e. into the in- 
terior of the lobules. Those vessels,seen and described by 
Neumann, are, as 1 have already pointed out, merely lym- 
phatics belonging to the connective-tissue septa between 
the lobules of the fat-tissue, and for this reason they may 
be described as the ¢nterlobular lymphatics. Comparing 
Neumann’s drawings with my own,I am led to conclude that 
the former saw very much fewer interlobular lymphatics 
than J. I have also drawn attention to the difference in 
numbers of these interlobular lymphatics in the fat-tissue 
of the human skin and in that of mammals, they being 
greatly more numerous in the former than in the latter. 
The interlobular lymphatics take up everywhere fine lym- 
phatic sinuses and clefts which are traceable between each 
two fat-cells. In specimens successfully injected with 
Berlin blue, and especially in those with asphalt-benzole, 
these wtralobular or intercellular lymphatics are shown 
with great distinctness. ! will particularly draw the atten- 
tion of the reader to Figs. 1, 3, and Fig. 5, illustrating the 
ultimate lymphatics in the fat tissue of the skin of the dog, 
-and Fig. 4, showing the same in man. i 
* The asphalt-benzole, im a successful injection of the fat tissue, pene- 
trates generally a good distance into the lobule, but the different lobules
