On July 20, 1955, a 7-year-old Holstein cow was admitted to the Stange Memorial Clinic at Iowa State College, as a possible "hardware" suspect. The patient was badly bloated at the time of admittance. Rectal examination indicated a marked enlargement of the inguinal lymph nodes and right kidney. The blood count of the animal indicated a marked leucocytosis, 25,680. The differential count revealed 16,900 lymphocytes, 4,700 stabs, 3.800 segments and 200 monocytes.
