Spermin (sper'-min) \a-kppa, seed], C 2 H 5 N. A non- 

 poisonous alkaloid obtained from sputum, human se- 

 men, the organs of leukemic patients, and alcoholic ana- 

 tomic preparations. " Charcot's Crystals," " Charcot- 

 Leyden Crystals," or " Charcot- Neumann crystals," 

 are said to be simply phosphate of spermin. Such 

 crystals have been found in the sputa of emphysema 

 associated with catarrh, in the bronchial discharges of 

 acute bronchitis, in the blood and spleen of leukemic 

 and anemic patients, in the normal marrow of bones, 

 and in human semen. These crystals are said to be 

 identical with ' ' spermatic crystals ' ' a variety of crys- 

 tals formed in seminal fluid after prolonged standing. 

 According to Fiirbringer they are probably formed by 

 the action of semen on the prostatic secretion. As 

 these crystals are found almost constantly, after death, 

 in the fluid of the prostate, and not within the con- 

 tents of the seminal vesicles, they are more appropri- 

 ately termed prostatic crystals. (Piersol.) Sper- 

 min seems to have a very wide distribution in certain 

 diseases, especially leukemia. See also Piperazin. 



Spermism (sper'-rnizm) [arctpua, seed]. In biology,

 ment of a spermatozoon, the ovum acting only as an
