SUMMARY OF CURRENT RESEARCHES RELATING TO 
considerable distance. This is especially the case in fresh preparations r 
while in those that are preserved the processes are less distinct. The 
cells which are placed on the intestine may often be shown to have pro- 
cesses which branch upon the intestine, and form a kind of plexus on it. 
In good methylen-blue preparations it was often possible to see that the 
fine blue filaments pass into the muscular fibres. These can best be 
seen in the longitudinal muscles in the median and hinder thirds of the 
body. The author enters into considerable details as to the results of 
his observations of these cells. Dealing next with the terminal cells, 
he is enabled to show that the terminal cells of the excretory capillaries 
are completely closed and pass directly into the walls of these vessels. 
The latter consist of a very flat epithelium which is made up of a few 
cells. The terminal cells are provided with processes which radiate 
out between the parenchymatous cells. No cleavage spaces were seen 
between the latter cells, and the author is confident that they do not 
exist. The tuft of cilia carried by the terminal cell is of some length. 
Terminal cells appear to be wanting from the suckers and pharynx. 
The subcuticular cells, to which considerable attention has been 
devoted, and which have been the subject of very various explanations, 
are next considered. The author thinks that the number of hypotheses 
about them is sufficiently large to justify him in refusing to add to their 
number. 
Tsenia dendritica Goeze .* — Tsenia dendritica , says M. E. Riggen- 
bach, has hitherto only been found in the intestine of the Squirrel. The 
length of the worm is 10-15 cm., the breadth increases from 0*24 mm. to 
1 • 5 mm. The scolex is round, there is no rostellum, and the vertex is 
flat. There are four suckers. The ripe proglottides are 6-8 times as 
long as broad. The genital sinus is situated about the second fifth of one 
side of each proglottid. When the uterus begins to form, the testicle and 
yolk-sac disappear, the vas deferens, vesicula seminalis, and receptaculum 
seminis remaining. The uterus extends along the length of the pro- 
glottid, and exhibits lateral flask-shaped diverticula. The ova in utero 
are 0*016 mm. broad and 0*002 mm. long. 
Cysticercus inermis in Cattle.f — In the slaughterhouse at Dresden 
a Cysticercus inermis , the size of a pea, was found in the gland of an ox 
which had been seized on account of advanced tuberculosis. Besides 
this, says Herr Noack, six others were found in the muscles after the 
animal had been cut up. 
Herr Mejer 1 narrates another instance of Cysticercus inermis , which 
was found in the interlobular connective tissue of the left lung of an ox. 
Besides this, another specimen was discovered in the tongue, three in 
the heart, and six in the muscles.
