This barrel of mineral oil was used by Dr. Michael Potter to induce plasma cell tumors in mice.

Potter wanted to study the early stages of tumor growth, but the tumors only grew in animals. Each of these containers holds the bones of one mouse. The labels indicate the mouse’s identifying number, gender, and colony, as well as what the mouse was injected with, such as “1 dose one Fruends adj + Staph” or “mineral oil only,” and when it was injected. Potter would inspect the bones for lesions about 90 days after tumor X5563 had been transplanted into the mice.
