348 HUMANE TREATMENT OF ANIMALS USED IN RESEARCH 
The Rockefeller Institute, 
New York, N.Y., September 26, 1962. 
Mrs. Christine Stevens, 
Animal Welfare Institute, 
New York, N.Y. 
Dear Mrs. Stevens : I regret that I could not find the time to look into 
the details of the bill before Congress concerning the regulation of animal 
studies. The best I can do is to restate to you the general meaning of my 
statements when you visited my laboratory some time ago. 
I believe that there is room for much improvement in several medical 
schools and research institutes with regard to the housing facilities for ex- 
perimental animals. I believe such improvements are important for the wel- 
fare of experimental animals but also for the quality of experimentation. For 
this reason grants in aid now given for animal experimentation should in- 
clude items for the renovation and upkeep of animal quarters. 
Yours sincerely, 
(S) R. Dubos

Dear Congressman Roberts : Enclosed is a report of my visits to an animal 
laboratory in a Detroit hospital. The report is factual, accurate, and without 
prejudice. 
I was not sure whether my report could be printed in the Congressional 
Record if I specified the name of the hospital and the doctors involved. Be- 
cause everything I have stated is a matter of record on file with the Michigan 
State commissioner of health, I have no objection if the names are used. In 
fact, if it will help the cause to obtain legislation for “humane treatment of 
laboratory animals” I would prefer that names be used. I shall leave this 
to your discretion. 
The name of the hospital is Harper Hospital, 3825 Brush Street, Detroit, 
Mich. The chief pathologist who accompanied me on my first visit is Dr. John 
McDonald. On our second visit we were accompanied by Mr. George Cartmill, 
director of Harper Hospital, and Dr. John McDonald, chief pathologist. On 
my third visit I was accompanied by Dr. Thadeus Jarkowski, a pathologist 
who works under Dr. McDonald. 
On Friday, July 27, 1962, I went to Lansing and registered a personal com- 
plaint on Harper Hospital to Dr. Albert E. Heustis, commissioner of health, 
3500 North Logan, in Lansing. This was followed by a written report to Dr. 
Heustis dated July 28, 1962. 
I shall gladly and promptly supply any other information you feel will be 
helpful. 
Sincerely, 
Mrs. Robert L. Dtce. 
Enclosure.

Subject : H.R. 1937, for humane treatment of experimental animals. 
Hon. Kenneth A. Roberts, 
Committee on Interstate and Foreign Commerce, 
House Office Building, Washington, D.C. 
Dear Congressman Roberts : In October of 1960 I started on a carefully 
planned investigation of Michigan hospitals and pharmaceutical houses where 
live animals are used for experimental purposes. Since that time I have visited 
12 such laboratories and I have witnessed some shocking evidence of neglect, 
abuse, indifference, and filth. 
In the interest of brevity, I should like to submit specific accounts covering 
three visits made within a year to one Detroit hospital. A formal complaint 
of the inhumane treatment of animals in this Detroit hospital has been registered 
by the writer, both in person and in writing, to the commissioner of health in 
Lansing, Mich., and is a matter of record.
