He was joint author and editor of the "Handbook for the Physiological Laboratory," the publication in which of the tortures of animals roused a feeling in the country that led to the appointment of the Royal Commission to inquire into these practices. And is he not now one of the editors of the _Journal of Physiology_, which continually details to the world experiments involving terrible torments? In his "Handbook of Physiology" we find such descriptions as the following:-- Page 319. "(109).--_Asphyxia by complete Occlusion of the Trachea_.--For this purpose a cannula must be fixed air-tight in the trachea, the mouth of which is of such form that it can be plugged with a cork. . . . The phenomena as they present themselves in the dog. . . . _First minute_. Excessive respiratory movements in which at first the expansive efforts of the thoracic muscles, afterwards the expulsive efforts of the abdominal wall, are most violent. Towards the close of the first minute the animal becomes convulsed. _Second minute_. Early in the second minute the convulsions cease, often suddenly; simultaneously with the cessation the expiratory efforts become indistinguishable. The iris is now dilated to a rim; the eye does not close when the cornea is touched, nor does the pupil react to light; all reflex reaction to stimuli has ceased. All the muscles except those of inspiration are flaccid, and the animal lies in a state of tranquility which contrasts in the most striking way with the storm which preceded it . . . _Third and fourth minute_. As death approaches the thoracic and abdominal movements which are entirely respiratory become slow and slower as well as shallower. . . . In the spasms which accompany the final gasps of an asphyxiated animal the head is thrown back, the trunk straightening or arched backwards, and the limbs are extended while the mouth gapes and the nostrils dilate. They are called by physiologists stretching convulsions." Page 320. "(110).--_Asphyxia by Slow Suffocation_.--When an animal is allowed to breathe the same quantity of air repeatedly and continuously out of a bag, the process being of much longer duration, the phenomena can be studied with greater facility." After this, is it "ill-natured or ill-mannered" to think that parents will _not_ be fortunate if "their children fall under the elevating influence of Dr. Sanderson's scientific and personal character"? We want to know how medicine is advanced by the agonies of these suffocated animals?
