104 HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 
STATEMENT QE CHRISTINE STEVENS— Resumed 
Mrs. Stevens. Professor Worden, as you have stated, is the direc- 
tor of the Pluntingdon Research Center. He is a biochemist and a 
veterinarian and a pharmacologist. He is coeditor of the “Handbook 
on the Care and Management of Laboratory Animals,” which I sub- 
mitted to the committee this morning, which is the well-known text, 
the very best one on this subject. 
Professor Worden is also the editor in chief of the scientific journal, 
Animal Behaviour, which is Anglo-American; it operates on both 
sides of the Atlantic. 
Should I also introduce Major Hume now, or just one at a time? 
Mr. Roberts. I believe just one at a time will be fine. 
We will have the pleasure now of hearing from Prof. A. N. Worden. 
The Chair would like to say that we are very grateful to you for 
coming. We know that you have traveled many miles, and probably 
in some bad weather, too, to be here, and we are certainly appreciative 
of your fine work in your own country. And we appreciate the ef- 
forts you have made to be here and give us the benefit of your testi- 
mony. We are very grateful to you. 
STATEMENT OE PROF. A. N. WORDEN, DIRECTOR, HUNTINGDON 
RESEARCH CENTER, HUNTINGDON, ENGLAND 
Mr. Worden. Thank you, Mr. Chairman and members of the 
committee. 
Mrs. Stevens has dealt with some of my credentials. At the present 
time I have responsibility for a group of research workers in England, 
including physicians, veterinarians, pharmacologists, toxicologists and 
others, all holding licenses under the Cruelty to Animals Act. I am 
a member of the Physiological Society, the Pathological Society of 
Great Britain and Ireland, the Nutrition Society, and many other 
learned bodies. In the United States, I am a charter member of the 
Society of Toxicology, a diplomate of the Board of Laboratory Ani- 
mal Medicine, and a member of the American Society for Animal 
Production, the American Veterinary Medical Association and the 
Animal Care Panel. 
I am joint editor of the “Handbook on the Care and Management 
of Laboratory Animals,” and editor in chief of the Anglo-American 
scientific journal, Animal Behaviour, while I have published some 50 
original scientific papers that relate to experiments on living animals. 
I am grateful for the privilege of appearing before you today. 
This is the fourth time within the past 2 years that I have had the 
pleasure of coming to the United States of America. On previous 
visits I have had the opportunity of seeing experimental animals in 
over 40 laboratories in 9 States, some of these laboratories on several 
occasions. Such laboratories include those of Government institu- 
tions, nonprofitmaking bodies, independent organizations, and phar- 
maceutical concerns. I have, in addition had many discussions with 
American research workers, here and in the United Kingdom and 
elsewhere, and I would agree with the contention that there has been 
considerable misunderstanding of the privileges and rights of individ- 
ual research workers in the United Kingdom under the Cruelty to 
Animals Act.
