aseptically, and the healing of the wounds, as a rule, takes 

 place without pain. If the antiseptic precautions fail, and 

 suppuration occurs, the animal is required to be killed. It is 

 generally essential for the success of these experiments that 

 the wounds should heal cleanly and the surrounding parts 

 remain in a healthy condition. Experiments involving the 

 removal of important organs, and even of parts of the brain, 

 are performed without causing pain to the animals ; and after 

 the section of a part of the nervous system, the resulting 

 degenerative changes are painless. 



In the event of a subsequent operation being necessary in 

 an experiment performed under Certificate B, or B linked 

 with EE, a condition is attached to the license requiring all 

 operative procedures to be carried out under anaesthetics of 

 sufficient power to prevent the animal feeling pain. 



In no case has a cutting operation more severe than a 

 superficial venesection been allowed to be performed without 

 anaesthetics. 



The experiments included in Table III. (B.), 9596 in 

 number, are all performed without anaesthetics. They are 

 mostly inoculations, but a few are feeding experiments, or 

 the administration of various substances by the mouth, or the 

 abstraction of a minute quantity of blood for examination. In 

 no instance has a certificate dispensing with the use of anaes- 

 thetics been allowed for an experiment involving a serious 

 operation. Inoculations into deep parts, involving a prelimi- 

 nary incision in order to expose the part into which the inocu- 

 lation is to be made, are required to be performed under 

 anaesthetics, and are therefore placed in Table III. (A.). 



In the last Report which I had the honour to submit, I 

 explained fully the reasons why inoculation experiments are 

 regarded as being experiments calculated to give pain, and 

 therefore come under the Act 39 and 40 Vict. c. 77. The 

 local affection and the state of illness which may be induced 

 by the inoculation, and which may lead to the death of the 

 animal, although they may not be attended by acute suffering, 

 are of such a nature as to bring these proceedings within the 

 category of "experiments calculated to give pain." 



In a very large number of the experiments included in
