the parasite and also in the layers of the outer capsule 

 nearest to the centre, but have not detected them towards 

 the periphery. So far, we have not found any in the lumina 

 of small blood-vessels, those present, which were usually 

 straight or sometimes slightly coiled, lying in the fibrous 

 stroma presumably in lymphatic channels. Smears made 

 by shaving off layers of the outer capsule, have shewn 

 occasional embryos before the central worm-mass was 

 reached. We have examined, with negative results, the 

 following series of thick blood films, stained after removal 

 of the haemoglobin by distilled water. These films were 

 all taken at night (6 p.m. to 2 a.m.) in case of nocturnal 

 periodicity of the embryos. 



1. From ear of bullock: — Worm-nest on breast about 



sixth rib. Supposed to come from Northern Territory 

 of South Australia. 



2. Prom ear of bullock:— Worm-nests on both breasts 



about fifth rib. 



3. From foot of bullock:— Two large worm-nests one on 



each breast about fifth rib. Upper Hunter River, 

 New South Wales. 



4. From foot of bullock: —Worm-nest buried in flesh at 



point of brisket and fourth rib. 



5. From ear of bullock:— Worm-nests on each brisket 



from second to eighth rib. Queensland bred. 



6. From foot of bullock:— Worm-nest embedded in flesh 



7. From foot of bullock :— Worm-nests on brisket. 



Queensland. 



8. From foot of bullock:— Large worm-nests on each 



brisket, about fourth rib. Upper Hunter River, New 

 South Wales.
