Finely laminated calcareous precipitate. The specimen may have been presented by BROWN, According to his book "Eisenbach (...) hath also hot Baths; the Sediment of which is red, and turneth into stone; so that 1 brought away with me pieces of it of five or six inches diameter: I took also a large piece of this water petrified as it fell from a spout in which the waves of it are to be seen". À..3. An Incrustation, out of the Pipes that convey the Water into the Baths of Buda, brought thence Dr. E. Brown. {E-4-15} Dark brown, botryoidal encrustation. BROWN (1687) visited eight baths and described incrustations from two of them: In the "Bath of the green Pillars" (now Rudas bath) "the water ... is impregnated with a petrefying Juyce, which discovers it self on the sides of the Bath, upon the Spouts, and other places, and makes a grey Stone. The exhalation from the Bath reverberated by the Cupola, by the Irons extended from one Column to another, and by the Capitals of the Pillars forms long Stones like Isicles, which hang to all these places." The water of the "Bath of Velibey" (now Császár bath) "hath a strong sulphureous smell, and a petrefying Juyce in it". À..4. White Spar, from the Sweating-Bath at Glassiten <Glashütte> in Hungary. Dr. BROWN. (E-4-16) White, massive, calcareous encrustation. According to BROWN (1673) "the Springs are very clear, the Sediment is red and green, the wood and seats of the Baths under water are incrustated with a stony substance, and silver is gilded by being left in them (...) the sides of the Bath are also covered by the continual dropping of those hot Springs, with a red, white, and green substance, very fair and pleasing to the eye." p. 14. Appendix I. Crystals and Spars tinged with various Colours, by means of metallick and mineral Matter that is incorporated with them. p. 17. Lapides Venarum; seu materia lapidea varia in Venis Metallicis alijsque stratorum Saxeorum Fissuris, reperta. VEIN-STONES. Sales, salts. V.13. Vitriolum nativum album striatum <Striated native white vitriolx From the Gold Mine of Cremnitz <Kremnitz> in Hungary. 'Tis found along with the striated Antimony and the Gold-Ore, about 300 Fathom deep. 'Tis very white when first taken forth: and the Striae, or rather Threads, run a-cross the Veins. {E-8-13}
