Paper, 'On the compounds of ammonia with selenium dioxide' by Charles A Cameron and John Macallan The authors write: 'The following experiments were undertaken with the object of determining the action of ammonia upon selenium dioxide. They have resulted in the discovery of two new compounds, which, from what has been ascertained regarding their constitution, may, perhaps, be best designated by the term selenosainates or ammonium salts of an acid—selenosamic—yet to be isolated.'
