Look, it's Georges Méliès in this video :-P

1
00:00:26,000 --> 00:00:31,000
The subject is immobilized
on the operation table.

2
00:00:58,500 --> 00:01:02,900
Isolation of the nerve
and the left carotid

3
00:01:03,000 --> 00:01:07,500
and the insertion of
the trocar in the carotid.

4
00:01:52,000 --> 00:01:58,500
The bleeding is pushed until
the extension in the forelimb

5
00:01:58,600 --> 00:02:05,000
is detached, so you can see
the important sign of agony.

6
00:02:16,000 --> 00:02:21,500
This dog weights 21 kg, giving a bleeding
of 1400 ml, 1100 ml citrated serum

7
00:02:21,600 --> 00:02:27,000
is injected through the right saphenous,
or about 4/5 of bleeding.

8
00:02:45,000 --> 00:02:51,000
The operation is over, the dog
gets up, walks, drinks...

9
00:03:12,000 --> 00:03:16,000
... and the next day he has
completely recovered.

Uncomfortable viewing. Animal experimentation is a subject that deeply confuses me ethically.
