**CONJOINT Degrees**, in music, two notes which follow each other immediately in the order of the scale, as ut and re.

**CONJOINT Tetrachords**, two tetrachords, or fourths, where the same chord is the highest of one and the lowest of the other.

**CONISSALÆ**, in natural history, a class of fossils naturally and essentially compounded, not inflammable, nor soluble in water, found in detached masses, and formed of crystalline matter debased by earth.

Of this class there are two orders, and of each of these only one genus. Conissale of the first order are found in form of a naturally regular and uniform powder; all the genuine particles of which are nearly of one determinate shape, appearing regularly concreted, and not fragments of others once larger. Conissale of the second order are found in form of a rude, irregular, and shapeless powder, the particles of which are never of any determinate figure, but seem broken fragments of once larger masses.

To the former genus belong the different kinds of sand; and to the latter the saburræ, or gritts.
