lished. At Monte Video it is believed that Dr. Sanarelli 

 has succeeded, and it is believed that he will win the re- 

 ward of about ^30,000 offered by the Brazillian Govern- 

 ment. It may be remembered that the enthusiastic Ital- 

 ian biolog-ist cured himself of yellow fever caug-ht in the 

 course of his investigfations. — Scientific American. 



Diagnosis ofPregnancy with the Microscope. -Dr. Park, 



of Philadelphia, (Amer. Gyn. and Obstet. Jour.) reports 

 that after a microscopic study of the triple phosphates in 

 the urine of pre<^nant women, he is satisfied that they be- 

 gan to chang-e their form within twenty days after concep- 

 tion. The feathery appearance first disap])ears from the 

 tips of the crystals and progresses downward to the base. 

 Sometimes it occurs only on one side, but g-enerally on 

 l)oth. If the f(L^tus dies they resume their normal appear-

 that it can be made without the patient's suspecting the 

 object of the examination, and at a much earlier period 

 than any reliable physicial sign can be obtained. 



Fish Diet and Leprosy. Dr. Hensen, of Bergen, says: 

 "I do not think that there is any choice given to the bac- 

 teria of leprosy as to localization, just as there is none in 

 the tubercle bacillus. They develop wherever chance has 

 deposited them and wherever they find favoring conditions 

 and no obstacles; for example, on the outside of the arm 

 where there is little muscular movement. On the ex- 

 posed portions of the body, oxygen retains and feeds them. 

 The inoculation by insects can only be successful in these 

 ])laces; in others, circumstances are too much against 

 them. An internal inoculation is also easily imaginable 

 and even probable. Salt fish is eaten all over the world ; 

 raw fish is eaten only in some countries, like Japan. P'ish, 

 especially the carp, which is so general an alimentation in 

 Japan, where it is eaten raw and even alive, feed on the 

 larval' of mosquitoes, and may be suspected of commun- 

 icating the spores of disease extracted by the insects from 

 the exposed parts of diseased bodies. If not, however, 

 spores, then the toxins of the bacilli. In reflecting, then,
