(5J.8 ZPOLOPIPAP ^JTISRATURE. 
T. 3? On the PRi^asitic Origin of Pleuropneumonia in 
Qattle (read 2nd Dec. 1864^ and dated from Kpw, Mel- 
bourne, Sept. ^3rd, J864). Australian Medical Journal 
foj Jan. 1865 (pp. I-IO, with a coloured plate). 
The author carefully records the results obtained from an 
extensive series of microscopical examinations of the organs of 
animaljs dying of the disease above mentioned, and, from the 
quantity and variety of helminthic organisms encountered, he 
has persuaded himself that pleuropneumonia is of parasitic 
origin. The facts recorded are certainly not devoid of interest, 
but there are many statements in the paper the meaning of 
which is rather obscure. Thus (at p. 3), in a foot-note, he says. 
In applying the term encysting to Distoma, I wish to convey 
the idea that an ovum of Distoma passes into a cystic condition 
in place of developing as an animal.^^ Necessarily the author 
is at a serious disadvantage in not having ready access to recent 
helminthological writings ; yet, on the other hand, one does not 
understand from what source he can have learnt that Leuckart 
refers Linguatula ferox or Pentastoma denticulatum “ to some 
condition of a cestoid worm (p. 6) . Apart from these defects, 
there is much that is praiseworthy. The author figures an 
ovum of a Distoma found in a cyst in the lung ; and from what 
is written in the text (in paragraphs 5, 8, 9, and 13) we may 
infer that the egg in question had been obtained from an ox 
or cow. The greater part of the paper claims the interest of the 
veterinary pathologist rather than that of the helminthologist. 
CoBROLD, T. S. Note on Ccenurus, Journal of the Proc. Linn. 
Soc. viii. pp. 22-24 (with a woodcut), 1864. 
In this brief paper the author describes a form of Ccenurus 
taken from the viscera of an American squirrel, and expresses 
his belief in the existence of several kinds of Coenuri. He 
supports his view by referring to previously published cases, 
where Coenuri have been described as occurring in the viscera 
and soft parts of various animals ; referring, more particularly, 
to the writings of Rose, Numan (Over den Veelkop-blaasworm 
der Hersenen), and Leuckart. 
This paper has been reprinted in the Quarterly Journ. of Micro- 
scopical Science for January (New Series, No. xyii. p.929) 1865.

This communication contains a detailed account of the ana- 
tomical characters presented by an apparently new species of 
Pentastoma, great numbers of which were discovered by Prof. 
Bruckmiiller in the body of a lioness. The parasite was present 
in the omentum and mesentery, being more especially abundant
