colour ; one of them, however, has a slight eminence rising 
from the centre of the concavity, and is less florid in colour 
than the other. The whole mass is soft and pulpy, imparting 
a feel of a fluid being contained in a cell-like structure. 
There are no external indications of bone entering into the 
composition of the anidian, nor is sufficient hardness imparted 
to the feel to lead to the conclusion that osseous tissue exists 
in its interior. This point, however, must be left undecided, 
as it has been determined to preserve the specimen entire. 
Anidian monsters are not common, and their interest is added 
to when they are found to coexist with a healthy and fully 
developed foetus.

Essays on Horse-Shoeing. — The readers of the Veteri- 
narian will perchance remember that, as announced in several 
advertisements in this Journal for 1869 and 1870, and as we 
intimated in a leading article for September of the former 
year, the Scottish Society for the Prevention of Cruelty to 
Animals offered three prizes of £50, £30, and £20, for the best 
practical essays on horse-shoeing. 
The adjudicators appointed to examine the essays and 
pronounce upon their merits were four members of the veteri- 
nary profession and four non-professional gentlemen of well- 
known ability. 
These have at length given their decision, and out of more 
than forty essays, all more or less of considerable merit, have

Royal Engineers. 
Second Prize (£30). — T. D. Broad, M.R.C.V.S., Bath. 
Third Prize (£20). — George Armatage, M.R.C.V.S. 
We understand that Mr. Fleming’s essay, which is 
copiously illustrated, will be published at an early date ; but 
we believe it is not yet settled whether the other essays will 
be printed. 
Iron as a Deodorizer. — Dr. Voelcker calls attention to 
the use of spongy iron as a deodorising material of greater 
potency than animal charcoal. Sewage water passed through 
a filter of this substance is completely purified, and this 
filtered water, after having been kept six months protected 
from the air, was perfectly sweet, and free from any fungus 
growth. The spongy iron is obtained by calcining a finely
