In the year 1900 the same vivisector published an account of certain experiments on the respiratory system, 102 in all. We have the usual assurances of anaesthesia, which, of course, can only be regarded as the operator's opinion. Fire is an element of some of these experiments. We are told that "a large blow-flame burner used for glass-blowing supplied a flame that could be adjusted to a very great range of intensity." Of this statemnet one can have no doubt upon reading some of the experiments described. Upon "a healthy little poodle," weighing only ten pounds, with a blood-pressure of 120 millimetres, the following experiment was made: "The mouth was held wide open, and THE BLOW-FLAME DIRECTED INTO THE PHARYNX AND RESPIRATORY TRACT. The immediate effect upon the blood- pressure was A TEMPORARY RISE. Again the flame was applied; THE BLOOD-PRESSURE ROSE TO 204 MILLIMETRES, CONTINUING AT THIS HIGH RATE FOR SOME TIME." Probably this little creature was the pet of some child. From whose door, one day, did it wander, to be snatched up by some thief, sold to a laboratory, and sent to a death like this? In another experiment a Newfoundland dog "CONTINUOUSLY BREATHED THE FLAME FOR TWELVE MINUTES." In a similar experiment that followed, "the results were practically identical. In this case THE FLAME WAS SO INTENSE AS TO MELT THE ADIPOSE TISSUE AROUND THE TRACHEA." The animal was broiled alive. During the first year of the twentieth century the same writer presented the public an account of an "Experimental and Clinical Research into Certain Problems," a work containing a considerable number of experiments of a nature similar to those before published. We are again told that in all cases "the animals were anaesthetized, usually by ether, occasionally by chloroform," alone or combined with other substances, although, in a few cases, "CURARE and morphine were used"--neither of which is an anaesthetic. A curious statement seems to imply a confession that all these experiments were not absolutely painless, for the writer says: "Every precaution was taken to inflict AS LITTLE PAIN OR DISTRESS AS POSSIBLE." Is not this an admission that in some experiments there was pain? How senseless is such statement! When Ridley and Latimer were burnt alive at Oxford, the executioner might have protested with equal assurance that "every precaution was taken to burn the condemned with as little pain and distress as possible." Between the experiments recorded in this volume and those which have been reviewed, there is no very great difference. There is a rise of blood-pressure after any mutilation or stimulation calculated to cause pain, except in the few cases where a sufficiency of the anaesthetic appears to have been given; to these attention will be called. A new procedure seems to have been the use of the injection of a hot salt solution into the blood. Some of the results of experiments were as follows:
