ON STAGGERS. 
From the upper surface of tliis plexus many branches run 
upwards towards the intestines and kidneys; but the greatest 
number are distributed on the ovaria. ' 
“ The lumbar nerves on each side give off several branches, 
which pass at once into the oviduct. The last lumbar neiTes pass 
down upon the surface of the psoae muscles, and, near the pubes, 
give oft' a branch which takes a circuitous course towards the 
lateral portion of the bladder, and the extremity of the oviduct. 
The continuation of the aortic or.abdominal plexus, in union 
with some branches of the sacral nerves, forms, on each side of 
the pelvis, a kind of plexus, which distributes branches to the 
cloaca and lower portion of the oviducts. 
The nerves corresponding with those which have been de¬ 
scribed in the frog, run almost entirely in straight lines, instead of 
havino; the intricate reticulated texture of the visceral neiwes in 
O ^ _ 
hot blooded animals. The ganglia are indistinct, and the fibres 
that compose ' them resemble those of the muscular, more than 
the visceral nerves.’^

Sir, 
I BEG to enclose a short case of staggers, which, by permission 
of Mr. John Percivall, I have taken from the Royal Horse In¬ 
firmary, Woolwich. It may, however, not be irrelevant to offer 
a few observations on the nature of this disease. 
Authors have designated this disease under such a variety of 
appellations as must necessarily tend to confuse the student. 
Medical writers have, in the human subject, described no less 
than nine distinct species pf apoplexy, classing them as the 
symptoms evince their different characters. 
Mr. Wm. Percival, in his Elementary Lecture, has, I think very 
judiciously, divided this disease into two heads only, as it regards 
the horse. He observes that the brain may be primarily and 
actually diseased; or it may be sympathetically, or secondarily 
affected. W^ere any distinct teim to be given to the disease, I 
know of none more appropriate than apoplexia somnolenta. 
' Of the first of these divisions, the predisposing cause is plethora; 
and thus producing a determination of blood to the head, com¬ 
pression, and its consequences. The immediate cause, however, 
may be superinduced by different circumstances, which, though
