HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 107 
their allegations of uncritical and even sadistic experimentation are 
ill-founded. We believe also that the existence of the act is of value 
in dealing with parliamentary questions. I believe that among ex- 
perienced British research workers the vast majority would, on ma- 
terial consideration, favor the retention of our act. 
Many of us believe that it could well be brought up to date and 
recently I have had the privilege of personal discussions with our 
Under Secretary of State, Home Office, on ways in which this might 
be attempted. I am strongly of the opinion, however, that animals 
and research workers would both lose if the act were deleted from 
the statute book. I believe also that prior care in experimental plan- 
ning and avoidance of indescriminate and wasteful usage, are as 
important with animals as with other laboratory reagents. The free- 
dom of all and sundry to use animals indiscriminately would not in 
my opinion improve either the quality or the value of British re- 
search. 
It would I feel be discourteous to attempt comment either upon the 
provisions of bill H.R. 1837 or upon the general principal of whether 
or not legislation found to be satisfactory in the United Kingdom 
would prove acceptable in this country. As already indicated, I have 
been able to see American laboratories at will. The high opinion 
in which I hold individual research workers over here is reflected 
in the fact that I have successfully sought their collaboration in pre- 
paring a standard textbook on the care and management of laboratory 
animals, edited by Dr. William Lane-Petter of our Medical Research 
Council and myself and sponsored by the Universities Federation 
for Animal Welfare. 
My colleagues and I are contributing also to texts that are being 
produced in this country. If I were asked to give a frank opinion, 
however, I should be forced to agree with the contention that there 
does exist a wide difference in this country between the best and the 
worst of animal quarters, animal caretakers, and experimental facili- 
ties. Improvements are being urged by many persons, not least by 
those who are actively engaged upon research. 
Thank you very much for permitting me to appear before you 
and for listening to me. 
Mr. Roberts. Thank you very much. I certainly appreciate the 
restraint which you use in expressing your opinion on the bill before 
Congress. 
But I do feel that you certainly keep in mind the experience that 
has been had in the United Kingdom with this type of legislation. 
I wanted to note that you have engaged in some cooperative work 
with our Food and Drug Administration. I believe you stated that 
some programs have been discussed in detail in advance with the 
Division of Pharmacology, Food and Drug Administration, here in 
Washington. I would like to inquire a little bit about that type of 
cooperation, how it came about, and what were some of the results 
of that work. 
Mr. Worden. Well, sir, we have been asked in our organization to 
investigate the safety and other aspects of drugs and other substances 
which may be used in the United States and as such will form the sub- 
ject of an application here in Washington. I took the opportunity 
over 2 years to establish contact with your Division of Pharmacology,
