    Fig. 1.—Represents the ordinary appearance of lithic acid crys- tals, under the microscope. The crystals are rhomboidal prisms; thin, transparent, and of a yellow colour.—M. Rayer. Fig. 2.—Rhomboidal prisms of lithic acid, thicker than those de- picted in the preceding figure; and, in some instances, approaching to the cubic form. The cubic is much more rare than the rhom- boidal variety of crystal.—M. Rayer. Fig. 3.—Modified serrated tables of lithic acid found in very acid urine.—Dr. G. Bird. Fig. 4.—Serrated crystals of lithic acid, showing the crescentic structure obtained by precipitating urine by an acid. The serra- tions resemble a compact series of dark lines.—Dr. G. Bird. Fig. 5.—Lithic acid in cylinders.—Dr. G. Bird. Fig. 6.—The usual appearance presented by the lithate of ammo- nia ; namely, that of an amorphous powder, the particles of which are either collected together into little masses, or scattered over the field of the microscope.—M. Rayer. Fig. 7.—Are other forms assumed by the lithate of ammonia ; namely, dark-coloured globules dispersed through the amorphous powder; around a great number of which, minute radiating crys- tals, of the super-lithate of ammonia, in the form of a star, are dis- posed.—M. Rayer. Fig. 8.—Represents the appearance under the microscope, of the oxalate of lime formed by the precipitation of the lime in the urine, by the addition of oxalic acid. Fig. 9.—Crystals of oxalate of lime resembling two superposed cubes; and acute octohasdron, the form most usually found in de- posites.—Dr. G. Bird. Fig. 10. — Form occasionally assumed by the oxalate of lime, according to Dr. G. B. I have seen such forms, but did not know to what order to refer them. Fig. 11.—Represents a flat octoheedron; the form, stated by Wol- laston and others, to be that most frequently assumed by crystallized oxalate of lime. According to the observations of Mr. Brooke, however, some natural crystals of the oxalate of lime, containing one proportion of water, presented the form of an oblique rhombic prism. Whether the salts thus appearing in two different forms are the same in composition; or whether the octohaedral form has been erroneously assumed, is not ascertained.—See Lond. and Edin. Philos. Mag. vol. xvi. p. 449, (1840.)
