versely, when voluntary movements are impossible, the 

 muscle can contract itself by faradization. This phe- 

 nomenon is observed in certain amyotrophies. R., 

 Mixed, a reaction normal in the nerve and altered in 

 the muscle. It is called by Erb the middle form of 

 degenerative reaction. R., Myasthenic, that in which 

 the normal tetanic contraction of a muscle under fara- 

 dic stimulation becomes less intense and of shorter 

 duration with every consecutive stimulus and finally 

 ceases, the muscle being exhausted. Syn., Faradic 

 exhaustibitity. R., Myotonic, of Erb, contractions 

 caused by either the faradic or galvanic current and 

 characterized by attaining their maximum slowly and 

 relaxing slowly. The vermicular, wave-like contrac- 

 tions pass from the cathode to the anode. R., Neuro- 

 tonic, in electrotherapy, a tonic persistence of con- 

 traction, after the current has been broken, upon gal- 

 vanic and faradic stimulation of the nerve alone, in 

 contradistinction to the myotonic persistency that fol- 

 lows faradic stimulation of the muscle. [Jacoby.] 

 R., Pietrowski's, the biuret reaction. See Tests, Table 

 of (Illus. Diet.). R., Pfeiffer's, the addition of 

 some of the peritoneal effusion provoked in a guinea- 

 pig by inoculating it with a mixture of blood-serum of 

 an animal immune to cholera, and of bouillon to 

 which a small portion of a culture of the Spirillum 

 cholera asiaticce has been added, causes these organ- 

 isms to become nonmotile and to agglutinate. The 

 absence of this phenomenon proves that the spirillum 

 under investigation is of a different species. R., 

 Strauss', the injection of material containing the 

 bacillus of glanders into the abdominal cavity of a 

 male guinea-pig is followed in a few days by a char- 

 acteristic, generally purulent, inflammation of the 

 testes. R., Thread, a peculiar reaction, consisting in 

 the formation of long interlacing threads, produced 

 in certain bacteria, Bacillus coli communis, B. proteus, 

 etc. , when brought in contact with blood-serum, 

 especially that blood-serum obtained from the body of 

 the individual whence the bacteria were obtained. 

 Syn., Filamentation ; Thread- formation. Ger., Faden- 

 bildung. R., Wernicke's. See under Signs (Illus. 

 Diet.). R., Widal's, the addition of a few drops of 

 a culture of Bacillus typhi abdominalis to the serum 

 of a typhoid fever patient causes an agglutination and 

 loss of movement of the bacilli.

 ward into the tympanum, transmits, through an aperture 

 at its apex, the tendon of the tensor tympani. Syn., 

 Carta lis tensor tympani; C. tensor tympani ; Fossa 

 coch lea riform is .

 R. of the First Order, one that unites with a toxin. 

 R. of the Second Order, one that has two hapto- 

 phore groups, one of which unites with a nutritional 

 substance (immune body) and the other with a fer- 

 mentative substance (complement). (Gay.)
