690 THL ANIMAL PARASITES OF MAX 



continue to live for a very long time in the biliary passages. When 

 the worms infect the biliary passages through the invasion of intes- 

 tinal bacteria, liver abscesses arise (Dauernheim, 1 Saltykow 2 ). 

 Leer 3 goes so far as to maintain that Ascarichv may be the second 

 most frequent cause of liver abscesses. That Ascaris in the pancreas 

 may simulate liver abscess in a remarkable fashion is shown by 

 Vierordt's 4 observation, which is quite unique, while Ascaridcc have 

 been found to occur in isolated instances in the excretory ducts of 

 the pancreas and in its branches, where they have remained living for 

 a long time. 



It is no rare occurrence for Ascaridcv, in consequence of their 

 migration into the stomach, to be ejected by the act of vomiting, and 

 in such way to gain access into the upper air passages, or to find 

 their way during sleep into the nose or accessory sinuses (Mosler and 

 Peiper"') without giving rise to special symptoms. For example, 

 Troja 6 found in the frontal sinus of a cadaver a large coiled-up 

 Ascaris which occupied the whole cavity. Wrisberg 7 made the same 

 observation in the cadaver of a boy. Deschamps 8 and Fortessin'^ 

 mention an Ascaris being met with in the antrum of Highmore. 

 Observations of the discharge of living or dead Ascarides from the 

 nose are frequently recorded. To this class belongs the case 

 mentioned by Albrecht, 10 in which an Ascaris was removed from the 

 nose of a girl, aged 7 ; also the case recorded by Benievini, 11 from 

 the nose of one of whose friends a worm escaped ; he had suffered 

 from the most violent headaches, fainting fits, dimness of vision and 

 vomiting; after the escape those untoward symptoms disappeared. 

 Similar records have been made by Forest, 12 Lanzoni, 13 Langelott, 14 

 Tulpe, 15 Reisel, 16 Fehr, 17 Bruckmann, 18 Bahr, 19 Slabber, 20 Lange, 21 

 and Chiari. 22 A rarer case is that recorded by Haffner, 23 that of a
