HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 35 
are performed shall be treated with strict antiseptic precautions, and if 
these fail and pain results, the animal shall be immediately killed under 
anaesthesia. 
Condition No. 6 applies to all experiments under Certificate C. It 
requires that on the completion of any such experiment the animal shall 
be killed forthwith by, or in the presence of, the licensee. 
Condition No. 7 states that no experiment in which curare or other 
substances having similar curare-form effect upon the neuro-muscular 
system is used shall be performed without the special permission of the 
Secretary of State ; and forty-eight hours’ notice of the performance of 
every experiment or series of similar experiments so permitted shall be 
given to the Inspector of the District. This condition does not apply 
to experiments on a decerebrated animal in which the cerebral hemispheres 
and basal ganglia have been destroyed. 
This condition is based on Section 4 of the Act, which says that the 
substance known as urari or curare shall not for the purposes of this Act 
be deemed to be an anaesthetic. 
Substances regarded as having a curare-form effect are those 
substances which, in the doses used, will produce motor paralysis without 
anaesthesia. 
Condition No. 8 states that the licensee must keep a written record of 
all his experiments, which shall be open to examination by an Inspector 
at any time ; and he shall send to the Secretary of State within fourteen 
days at latest of the close of each year a report of the number and nature of 
all experiments performed during the year, and from time to time such 
other reports as may be required. 
A record of all experiments being carried out under the Act should 
be available at all times in the laboratory or animal house ; either in the 
form of full details provided on the cage label or in the form of a record 
book to which cage labels refer. The form of record supplied with the 
licence to each new licensee is intended as a guide. Any suitable form of 
record keeping may be used, providing it gives at least as much inform- 
ation as is indicated on the official form. 
About the middle of December of each year the Home Office sends to 
all licensees a special form on which an annual return is to be made. 
Condition No. 9 states that in the event of descriptions of any 
experiment performed by the licensee and requiring a licence under the 
Act appearing in any medical, scientific, or other journal or magazine 
or in a report of any lecture delivered by the licensee printed for publica- 
tion or private circulation, the licensee shall transmit to the Secretary of 
State, as soon as practicable after its appearance, the said journal or 
magazine, or the fullest of such printed publications or reports of lectures, 
accompanied by a letter drawing attention to the description of the 
experiments performed by him and stating when and where the experi- 
ments were performed. The submission of reprints, etc., as they become 
available, instead of at the end of each year, is particularly requested by 
the Home Office. 
Condition No. 9a states that the licensee shall not permit any cinema- 
tograph film to be made which shows any animal, or a part of it, under- 
going an experiment performed by him under this licence, except with the 
prior consent in writing of the Secretary of State and unless the person or 
body in whom the copyright of the film when made will be vested has,
