ACT 39 AND 40 VIC. C. 77 



without anaesthesia, in cases where the only instru- 

 ment used is a needle. It is hardly reasonable, for 

 instance, that the inoculation of a mouse should be 

 scheduled as a painful operation performed without 

 anaesthesia. The disease, thus painlessly induced, 

 may in many cases be called painless ; for instance, 

 snake-venom in the rat, septicaemia in the mouse, 

 malaria in small birds. In other cases, there are 

 such pain and fever as are part of the disease. 

 The form that rabies take in rabbits may fairly be 

 called painless. Inoculations not under the skin, 

 but into the anterior chamber of the eye, are very 

 seldom made ; they sound cruel, but cocain renders 

 the surface of the eye wholly insensitive, and the 

 anterior chamber is so far insensitive that a man 

 with blood or pus {hypopyon) in the anterior 

 chamber of the eye may suffer no pain from it. A 

 horse or an ass kept for the giving of an anti- 

 toxic serum has a more comfortable life than an 

 omnibus horse ; and this preparation of the anti- 

 toxins, since it is not an experiment, but a direct 

 use of animals in the recognised service of man, 

 does not require a license or certificates under 

 the Act. But the testing of an antitoxin is an 

 experiment, and must be made under a license and 

 Certificate A. 



It is not the business of this book to consider 

 whether the sensitiveness of a dog, a rabbit, or a 

 guinea-pig can fairly be stated in terms of the 

 physical and mental sensitiveness of men and 

 women. In the world of animals, as in the world 

 of humanity, there are differences of sensitiveness.
