plant scattered about, but by the perennial underground 
mycelium, which slowly spreads, until it is killed by meteoro- 
logical causes, or like other plants, dies out from exhausted 
vitality.” 
This author gives diagrams of mole tracks, in support of 
liis theory, but the following objections to his view of the 
matter appear to us insuperable. 
1st. — Fairy rings may constantly be seen where the mole 
has never been noticed, as in our own meadows. 
2nd. — Moles even when they make tracks do not kill the 
grasses, but, on the contrary, make such grasses grow more 
luxuriantly. 
3rd. — Fresh upturned soil is not favorable to the growth 
of fungi, but, on the contrary, these seem to be favoured by 
the presence of decaying matter, and our May mushroom 
especially is nourished by the roots of dead and decaying 
grasses. The quantity of phosphoric acid and potash in both 
grass and fungus will show that the one is fed on the ele- 
ments of the other, and the use of phosphatic manures has 
tended to the growth of the common mushroom even in our 
arable fields. 
Seeing, then, that so much has been said and written on the 
subject of fairy rings which is not deemed conclusive as ex- 
plaining the phenomena connected with them, the question 
may be asked, Is there a better solution at hand, or is there 
anything to add in elucidating what has already been ad- 
vanced ? 
Now, without presuming to lay claim to the first position, 
we may yet endeavour to add to observed facts, and we shall 
therefore in our next give an account of our own observations 
and conclusions upon this interesting subject.

TWO CASES OF PURPURA WITFI INTESTINAL 
SUBMUCOUS HAEMORRHAGE. 
By J. T. Thompson, M.R.C.Y.S., Sheffield. 
On reading an account of a case contributed by Professor 
Brown in the May number of the Veterinarian last year, I 
was struck with the great similarity to one that occurred in 
my practice in the summer of 1866, and having recently met 
with another of the same character, I thought a short history 
of them might be interesting to the readers of that journal.
