282 HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 
Then it was learned that dogs reacted to this red No. 32 in the manner of humans. 
Now FDA is carrying on lifetime tests of certain food colors with dogs. 
Aramite, a cancer-inciting miticide, was first tested on rats and mice with 
only small tumors noted. Later, Aramite was tested on dogs and produced can- 
cers of the bile ducts. A second scientific panel appointed to consider the effects 
of this miticide gave it a zero tolerance — setting aside the tolerance of 1 part per 
million given it by the first scientific panel after evaluating the tests on rats and 
mice. 
Officers of this federation had the privilege several years ago of touring the 
facilities of FDA, the consumers’ agency, and there observed many species of 
animals being used to test the potency and purity of medicines, insecticides, 
cosmetics, dyes — the potency of vitamins. This tour dramatically disclosed the 
value and importance of animal experiments. Soon primate centers will be estab- 
lished at two outstanding medical schools to study the causes of heart and cir- 
culatory diseases. 
Frequently the public reads newspaper accounts of new surgical techniques 
developed through operations on experimental animals. Rarely does the public 
know of the many animals sacrified before such experiments are successful. And 
seldom does the public learn that the care and caging of these medical matryrs 
should be improved — that in certain instances these poor animals are abused and 
negelected — even sadistically mistreated. 
The informed public who know to a degree the debt they owe experimental 
animals will support legislation aimed to relieve the suffering of these poor ani- 
mals who have saved humans much physical suffering and even their lives. Al- 
though the members of our organization have never visited private laboratories 
which use experimental animals, they have been saddened to read of the mis- 
treatment, neglect, and callous treatment which certain unfortunate animal vic- 
tims have needlessly endured. This information has been obtained through 
reading pamphlets distributed by local humane societies and materials furnished 
by the Animal Welfare Institute. However, federation officers were distressed 
to see the FDA dogs, used in lifetime tests of food dyes, living in small, tiered, 
wire cages in a crowded room in the subbasement of the South Agriculture 
Building. These officers rejoice that these poor animals will soon have com- 
fortable quarters and exercise ramps in a specially constructed new building. 
The funds for this needed building were appropriated by Congress when it learned 
through testimony of animal welfare groups about the plight of these FDA dogs. 
It is the understanding of this federation that the proposed legislation now 
being considered will not interfere with scientific research and investigation. 
Perhaps it will further it. It seems sensible to assume that animals humanely 
cared for will produce more valid and conclusive results than those who are 
neglected and abused — unless the research itself is directed to the effect of neglect 
and unkindness on living creatures. 
Mr. Chairman, it has been a pleasure to appear before your committee again — 
especially to support legislation which will provide humane treatment for 
laboratory animals used in research for the benefit of humanity. 
Mr. Roberts. Mrs. Peyton Plawes Dunn. It is a pleasure to have 
you. I have been told by some friends and, of course, I knew of your 
father’s work in the Congress and in the Senate, and the high respect 
in which he was held. I know he did a lot of work later on after he 
left public life — not public life but political life — as one of the very 
important men in the Wildlife Federation movement. It is certainly 
a pleasure to see you carrying on in the great tradition in which he so 
distinguished himself. 
STATEMENT OE MRS. PEYTON HAWES DUNN, WASHINGTON, D.C. 
Mrs. Dunn. Thank you very much, Mr. Chairman. I want to say 
that I was impressed with the way you handled this roomful of people 
yesterday. Solomon would have had a difficult time. You did a 
wonderful job and I am grateful for the opportunity to speak. 
Mr. Roberts. You are very kind.
