 octahedral or hexahedral crystals found in the sputum 

 of asthma and fibrinous bronchitis and in other forms 

 of sputum, in the blood in leukemia, in the intestines 

 in infection with parasites, and in nasal polypi ; they 

 are stained yellow with iodin. Cf. C.s, Spermin.

 See C.s, Charcot- Ley d 'en' s. C.s, Coffin-lid, crystals 

 of triple phosphate found in the urine in dyspepsia and 

 cystitis. See Table of Urinary Sediments (Illus.

 C.s, Ear. See Otolith (Illus. Diet.). C.s, Flor- 

 ence's, those produced in semen by treatment with a 

 solution consisting of 30 parts water ; 1. 65 parts iodin ; 

 and 2.54 parts potassium iodid. The reaction is pro- 

 duced under the cover-glass. The drop of iodin solu- 

 tion is placed upon the slide ; a drop of spermatic 

 fluid, or a watery extract of a suspicious spot, is placed 

 near by, and then the cover-glass is so placed that the 

 line of contact of the two fluids meets near its center. 

 At the point of contact of the two fluids there is im- 

 mediately formed a layer of granules and crystals. 

 The crystals are of a long, rhombic form, about 

 three times as long as broad. Sometimes they are 

 much longer and look like needles. These crystals 

 are brown in color, and dichroic. C.s, Hedgehog.

 den's. See C.s, Charcot-Leyden's. C.s, Lu- 

 barsch's, minute crystals found postmortem in the 

 epithelial cells of the testis, and regarded as distinct 

 from Boettcher's and Charcot's crystals. C.s, Neu- 

 mann's. Same as C.s, Charcot-Leyden's. C.s, 

 Schweiner's. See C.s, Charcot-Leyden's. C.s, 

 Spermin, a combination of phosphoric acid with a 

 base spermin (C 2 H 5 N), forming long, monoclinic, 

 prism-like crystals with curved edges, found in sper- 

 matic fluid after drying it or allowing it to stand and

 and potassium iodid stains them a deep brown or vio- 

 let. Syn., C.s, Boettcher's. Cf. C.s, Charcot-Leyden's.
