The present paper gives an account of tests carried out with the automatic ''Coleman'' apparatus to determine the nitrogen content of tobacco. Preliminary experiments made with different tobacco types led to the determination of optimum operating conditions which give exact and reproducible results. The values obtained by this procedure are the same as, or slightly superior to, those obtained by using the Kjeldahl method associated with the use of an efficient catalyst.
