## Abstract 1. A modified Nessler reagent in which the ratio HgI~2~ : KI : NaOH is 1 : 2.2 : 20 is described. It is clear and ready for immediate use and is less susceptible to interference by various cations. Distillation with phosphoric acid was satisfactory for preparing ammonia‐free water. The

## Abstract The total nitrogen content of plant tissue may be determined by direct nesslerization of sulphuric acid‐hydrogen peroxide digests with accuracy up to 5%. Similar application to soil extracts involves somewhat greater errors. In a spectrophotometric study of the Nessler colour, a filter
