These binary molecules are grouped by threes fours, fives, etc. (त्र्यणुक, चतुरणुक) to form different isomeric modifications. The variety of Earth-substances is due to differences in the arrangements of the molecules, (e.g. their greater or less density, and, above all, their grouping or collocation व्यूह, अवयवसंनिवेश), which account for the specific characters (अपरजाति) manifested by these isomeric substances. सा (पृथिवी) च स्थैर्याद्यवयवसंनिवेशविशिष्टा अपरजातिवत्त्वोपेत।। Prasastapáda, पृथिवोनिरूपणम्। स्थैर्यं निविडत्वम्। आदिश्ब्दात् प्रशिथिलत्वादिपरिग्रहः। परमाण्वादिषु अपरजात्याभावेऽपि अदृष्टवशात् तथा तथा तेषां व्यूहः यथा यथा तदारब्धेषु अपरजातयो व्यज्यन्ते। S'ridhara, Kandalí, ibid.
