ENCEPHALITIS — FHRENITIS — MAD SIAGGERS. 19 



should be done as quickly as possible. Supposing the blood can 

 be collected in a blood-can, or water- pail — for this cannot on all 

 occasions be accomplished — in general we shall find, from two to 

 three gallons require to flow before this effect be produced : so much 

 depending upon the size, condition, constitution of the horse, and 

 other circumstances. I used to consider the jugular vein to be quite 

 as good a channel as — if not a better than — the temporal artery for 

 blood-letting in affections of the head ; but some striking cases I 

 have had in my own practice have greatly altered my former opi- 

 nions ; and I find I am very much borne out in these altered views 

 by the reports of others. At the same time, I wish it to be under- 

 stood, that arteriotomy is in no case to be confided in, unless 

 blood can be obtained from one, or both temporal arteries, in a full 

 and fast stream : a dribbling or tardy current will avail nothing, 

 and need not be persisted in. 



In a communication many years ago from my respected friend, 

 the late Mr. Cordeaux, who served thirty years as a V.S. in the 

 Artillery, he informs me, "he has seen eminently good effects 

 from bleeding from the temporal artery, in six or seven instances ; 

 that two cases, which were considered hopeless, after several inef- 

 fectual bleedings from the jugulars, recovered, he verily believes, 

 from an accident that befel them during the night, by which the 

 pins were torn from their temples, and considerable quantities of 

 blood in consequence had escaped, and were found next morning 

 in their mangers." I have myself had several cases which were de- 

 spaired of, until, as a last resource, while the animals were despe- 

 rately struggling and throwing themselves about, I have contrived 

 to plunge the lancet into their temples, and allowed them to bleed 

 ad libitum, regardless of the quantity lost, paying attention, in fact, 

 only to effects: in several instances, to the surprise of all around, 

 has the frantic patient, from kicking about in a pool of blood, jumped 

 suddenly and unexpectedly upon his legs, and, after shaking himself 

 once or twice, appeared, like magic as it were, almost all at once 

 restored to his right senses. Mr. Rick wood, V.S. Bedford, has 

 likewise related a case in THE VETERINARIAN for 1830, which 

 tells eminently in favour of preferring blood-letting from the 

 temples. Mr. R. was sent for to attend a mare, who had just come
