attacks in g-eneral paralysis there is not only an increase 

 in the number of white cells but a chang-e in their charac- 

 ter, as shown by the differential count, and at times abnor- 

 mal cells appear, is an argument ag-ainst the theory that 

 leucocytosis is merely a change in the distribution of the

Filariae in the Blood. — ^At a meeting- of the Practi- 

 tioners' Society, of New York, Dr. F. P. Henry, of Phila- 

 delphia, related the case, which occurred in a female, aged 

 twenty-nine, who in early life had lived in South Carolina 

 and Florida and had never been outside the United States 

 {Med. Rec). It was, therefore, an indig-enous case, the 

 first one in Philadelphia; the infection had probably oc- 

 curred about the ag-e of twelve; the chyluria tirst mani- 

 fested itself shortly after normal labor. The filarial were 

 present in the blood of the mother alone, not in the milk, 

 nor in the blood of the infant. They were not very num- 

 erous, and were present at night only. The urine was re- 

 peatedly examined, but only once contained filarial. These 

 showed remarkable vitality under cold and heat, and one 

 specimen under the cover g-lass showed movements after 

 ten days. 



Reg-arding" treatment, Dr. Henry said that thymol and 

 quinine had no effect on the disease. The same was true 

 of methylene blue, which has been reported of value in one 

 case by Flint. In this reg^ard his observation was in ac- 

 cord with that of Lavaran. 



Dr. Henry referred to Manton's writing's, wherein it is 

 stated that the embryo came from an adult parasite over 

 an inch long-, located perhaps in the thoracic duct; that 

 the mosquito became infected and alighted on water, and 

 that it was by drinking- the infected water that man be- 

 came infected. There were three forms — the diurnal, the 

 nocturnal, and the persistent. 



Dr. Henry thoug-ht it possible for this affection to be- 

 come indig-enous to Philadelphia and other sections of our 

 country, althoug-h the likelihood of so larg-e a body of water 

 as the Schuylkill containing- a sufficient number of the par-
