PARALYSIS. 
193 
Your correspondent’s third principal impression, “on the 
toe when the animal gives a push by which an impetus is 
given to send the body forwards,” appears to me an admis- 
sion that the toe does come to the ground first, as progres- 
sion is only the result of impetus. I admit that the foot 
comes to the ground nearly flat, but the toe is for an instant 
on the ground before the heel. I would, in conclusion, add, 
that in approaching the central line of gravity in the progres- 
sion of solipedes, the toe and outer portions of the foot 
come to the ground before the heel and inner portions. 
Having been considerably interested by the communica- 
tions which appeared some months back on the above sub- 
ject, in the pages of the Veterinarian , and feeling that it is 
rather selfish to be always receiving and never offering that 
which we may be in a position to communicate to the pro- 
fession, I have been constrained to tender the results of my 
observations and experience, in confirmation of what has 
already been stated respecting paralysis. 
Paraplegia, or paralysis, to the extent of either a total or 
partial deprivation of voluntary motion, and sometimes of 
sensation, in the posterior extremities of the horse, is an 
enzootic of yearly occurrence in the counties on the immediate 
banks of the Tweed. The subjects of these attacks are not of 
any particular breed or age, and we find the disease also both 
in stabled as well as pastured horses, provided they are exposed 
to the same exciting causes. It seems to bear some analogy 
to other diseases; for example, such as “ Kumree” of the 
horse, which is peculiar to certain provinces of India, or 
ce Louping-ill a popular term given to an affection amongst 
sheep, common to many districts of our own country, 
although, as far as I am able to learn, it differs from them, 
both in its production and development. The usual season 
of its occurrence is spread over a period extending from the 
latter part of July to the early part of September. In its 
development it is generally gradual, differing in this respect, 
as in many others, from paralysis resulting from cerebral de- 
rangement or accidental injury. The affected animals are 
first of all observed to be weak in the back. In a day or
