Thus, chemical analysis not only furnishes objective data on the presence of alcohol in the body but also checks the reliability of statements with respect to ingestion of alcohol.Observations on the subject's physical and mental state and the results of chemical tests together constitute the data on which judgment of the degree of intoxication is made.Of the more than 200 analytical methods for ethyl alcohol, the majority have SN - 0002-9955 M3 - doi: 10.1001/jama.1959.63010010006010 UR - http://dx.doi.org/10.1001/jama.1959.63010010006010 ER -
