Bleeding Bread. — This affection which was epidemic in Eu- 

 rope t-even years auo has made its appearance in England. Mi- 

 croscopic spherical cells filleil with reddish oil give from a peach 

 blo.«som to a blood color to the medium in which they grow. 

 In the dark, the dei)osit extends itself by spurting a sort of jet or 

 column of red particles, so that a lar jc surAice is covered with

 S. T;iyIor of Uurliiigton, X. J., has Ijeen found to be affected by 

 tuberculosis. Out of a herd of 150 cows, some 20 have already 

 been killed and others are doomed, Mr. Taylor being determ-

 lowing results since its inauguration, July 2, 1890: 



To date 302 persons have been treated, classified as follows: 

 104 bitten by animals r- cognized and ascertained to be ral>id l)y 

 the experimental proof made in tiie laboratory ; or by the death 

 of other persons or animals bitten by the same animal ; 126 bit- 

 ten by animals recognized to be rabid by the symptoms of the 

 disease shown during life ; 72 bittt-n by animals strongly sus-

Only one death was reported among the patients treated, thus 

 giving a mortality of about 0.33 per cent. 



BIOLOGICAL NOTES. 



Red Blood-Corpuscle. — Dr. Moser has concluded that the 

 red blood-corpuscle has a distinct nucleus. He gave methylene 

 blue to a patient internally in one-grain doses three limes a day. 

 He then examined the l)lood and found tliat nature had done 

 the staining. Tiie nuclei of the wliite blood-corpuscles were
