THE VETERINARIAN, FEBRUARY 1, 1863. 
Ne quid falsi dicere audeat, ne quid veri non audeat.— Cicero. 
OUR PRESENT NUMBER. 
Our present number, apart from the communications of 
Professor Brown and Mr. Dyer, will be found to be more 
than usually replete with rare and interesting cases of 
disease. Affections of the cerebrum rightly viewed are 
among the most instructive which come before the investi¬ 
gator of pathology, and of these no less than four find a 
place in our pages. The one recorded by Professor Varnell, 
as occurring in the practice of Mr. Woodger, has but few, if 
any, parellels in veterinary medicine. We are not aware 
that the records of veterinary science, in this country at 
least, afford more than one instance of a so-called hydatid 
in the brain of the horse; and, as we have stated in a foot¬ 
note to Mr. Woodger’s case, even this was not a true 
example of the existence of the entozoon in the cerebrum, 
but rather of a eyst containing cholesterin. 
This immunity is the more remarkable when we consider 
4 
the frequency with which sheep are affected with hydatids; 
it not being very unusual for a dozen or more to be thus 
diseased in a flock of even a hundred. Why is this ? is a 
question far more easily asked than answered; but, never¬ 
theless, now that science has unravelled the mystery of the 
development of hydatids, it ought not to rest until light is 
shed on .the admitted fact of the entozoon being so fre¬ 
quently met with in some animals and very rarely in others. 
Here is a wide and a profitable field also for the helmin¬ 
thologist, and one we should desire to see cultivated by those 
who alone are fitted for the task by their knowledge of 
parasitic”development in general. 
We ought not to close these remarks without also direct¬ 
ing our readers^ attention to a most remarkable case of a 
needle being found floating loosely within the pericardial sac
