grown, and it is found in all climates, though it is more abundant in 
warm climates than elsewhere. 
The genus Ascaris has, in certain of its species, the power of 
attaching itself to the inner lining of the wall of the alimentary tract. 
Guiart has described specimens of A. conocephalus from the intestine of 
a dolphin: “profondement incruste dans la muqueuse, s’y etait taille une 
sorte de cupule assez profonde,” and Weinberg has reported the case of 
an Ascarid lightly attached to the duodenal mucous layer of an ape and 
at this point there was ulceration. The latter writer quotes a letter 
from Dr Fontoynot, Professor at the School of Medicine, Tananarivo 
(Madagascar), in which he says that A. lumbricoides is of extreme 
frequency in the natives (Malgache), in whom, among other troubles, the 
worms frequently set up a mild appendicitis. He states “ chaque fois 
que j’ai vu un indigene presenter du meteorisme abdominal, de la 
peritonie legere, ou mieux du peritonisme avec localisation manifeste de 
la douleur au point de MacBurney, et epatement dans la fosse iliaque 
droite, la santonine prise a la dose de 0T5 gr. a toujours fait evacuer un 
plus ou moins grand nombre d’ascarides et, par ce fait, a toujours amend 
la cessation de tous les phenomenes appendiculaires.” The further fact 
that he states that with one exception he has not met with grave 
appendicitis amongst the natives, to some extent explains the immunity 
of the highly parasitized Chinese, an immunity which has led Martignon 
(1901) to doubt whether entozoa play any part in setting up appendicitis. 
Weinberg also recounts an observation made by Aldo Castellaui on the 
extirpated appendix of a young girl, into which an Ascaris had pene¬ 
trated and in which one half of its body was firmly fixed. Between the 
parasite and the walls of the appendix was a purulent fluid charged 
with Bacillus coli. Other cases of the impaction of the worm are 
recorded by Kelly and Hurdon (1905): by Bergmann (1890), in which 
case the Ascaris had bored through the walls of the appendix and 
attained the perivisceral cavity: Arbord-Rally (1900) regarded a severe 
case of appendicitis in a boy of 10 years as due to Ascarids: Triboulet 
(1901) regarded another case as due to Ascariasis : Schiller (1902) states 
that the disappearance of certain caecal abscesses after the expulsion of 
Ascarids supports the view that they were the cause of the disturbance 
and in this tends to confirm the views previously expressed by Czerny 
and Heddaus (1898); Schwankhaus (1901) found in the peritoneal cavity 
of a boy of 13, who had died of diffuse peritonitis, an A. lumbricoides, 
which had bored its way through from the appendix : Nason (1904) de¬ 
scribed a case in which an Ascaris inside the appendix had so coiled
