ON FALSE PRESENTATIONS. 
By M. Giles, Y.S. 
Every practitioner has observed the unnatural position 
of the foetus when the head is either turned to the right or 
to the left; but no one, that the author is aware of, has 
pointed out the complication caused by the decubitus of the 
mother on the same side as that to which the head of the 
foetus is turned, which renders parturition impossible. 
In all the cases on which these observations are based 
there was always a chest presentation, the head being turned 
to the right, the mother lying on the left side. It is then 
impossible to bring back the head to its natural position, 
from the head and neck being pressed between the body and 
the ground; but by changing the position of the mother to 
the other side, there is little difficulty in bringing the head 
into its natural position. 
Another cause of diastocia is the narrowness of the vulva. 
This is the case only in the young cow with her first calf. 
The vulva being too small to admit of the passage of the 
head of the calf, the mother makes useless efforts to expel it 
by violent contractions of the uterus; and, becoming ex¬ 
hausted by these, life is endangered. To remedy this the 
author makes two incisions in the mucous membrane, one 
on the right and the other on the left side, and parturition 
is soon effected. These incisions give but little trouble after¬ 
wards, and sometimes heal by the first intention.

TWO CASES OE NOCTURNAL BLINDNESS (HEMERALOPIA) 
IN THE HORSE. 
By Roberto Bassi. 
The author, on observing this alteration in the vision of 
the horse, made a careful research to ascertain whether it had 
been mentioned by any veterinary authors, but he found only 
a short account of it in c Falke’s Handbuch aller Inneren 
und Einsseren Krankheiten,’ &c., p. 514, and this seems only 
to have been done to complete his nomenclature of the 
diseases in the domestic animals. Even Mons. Leblanc has 
not alluded to it in his work on the diseases of the eye, from 
which the author concludes that it is of very rare occur¬ 
rence. 
The first case that fell under his notice was at the end of 
the year 1857; a farmer’s horse, about eight years old, which
