Q. How can I view this article: "Rats in Relationship to Man's Welfare" by John B Calhoun online without paying a $50 membership fee?

None of Criss Library's databases include articles from Science in 1951; however, we have the bound volume shelved in the Periodicals Collection (call number Q1 .S35).  I scanned the article--it is only two pages--and you will find it in the attached PDF file.
