NISH (also written Nisch and NIS), the capital of the Nish department of Servia, lying in a plain among the southern mountains, on the left shore of the Nishava, a tributary of the Morava.
We see that in the term Nx z of the development the coefficient Nis equal to the number of partitions of n into k parts, with the parts I, 2, 3, 4, ..., with repetitions.
The monosulphide, NiS, is obtained by heating nickel with sulphur, by heating the monoxide with sulphuretted hydrogen to a red heat, and by heating potassium sulphide with nickel chloride to 160-180° C. When prepared by dry methods it is an exceedingly stable, yellowish, somewhat crystalline mass.
It should be noted that directly a magistrate entered an allied, independent state, he was obliged to dispense with nis lictors.
The latter probably also re-inked the whole of the NIS.
