The results of this study were: — 
1. To show that none of the 14 cases showed hook- 
worms of a species affecting man, and that therefore we 
have nothing to fear from them as transmitters of the 
disease, particularly the wild cats, which came from a 
notorious hookworm district. 
2. That the hookworm found in the young sea-lion 
has been described in young seals in the Pribiloff Islands 
{Urxinaria lucosi) and that its finding in these gardens 
indicates that it probably is present farther down the 
coast, namely in California. Our seal tanks are doubtless 
infested with eggs. We have probably had but this one 
case because there is so little sand in which eggs develop. 
The recent cementing in the enclosure is a valuable 
prophylactic measure.
