[…] In the opinion of the eight virologists these viruses are members of a previously unrecognized group which they suggest should be called the coronaviruses, to recall the characteristic appearance by which these viruses are identified in the electron microscope."; "This characteristic structural resemblance and other shared properties of these viruses have caused certain virologists to propose the name coronavirus for this previously unrecognized group."; "The virus, designated as rat coronavirus (RCV), exhibits properties representative of the coronavirus group: characteristic surface structure, particles somewhat variable in size averaging approximately 90 mμ, apparent RNA content, essential lipid, heat sensitivity, and a close serologic relationship with the mouse hepatitis virus complex."
