Evidence of a witness; evidence given by a witness, under oath or affirmation; as distinguished from evidence derived from writings, and other sources. Testimony is not synonymous with evidence. It is but a species, a class, or kind of evidence. Testimony is the evidence given by witnesses. Evidence is whatever may be given to the jury as tending to prove a case. It includes the testimony of witnesses, documents, admissions of parties, etc. Mann v. Hlggins, 83 Cal.
