*In a recent paper (19166) in which I gave a summary of recent work 
relating to this parasite, I omitted any reference to Dr. Nicoll’s last paper 
(19150), as I was not aware of it untillately. He has published an account 
of his efforts to find worms and larvae in ten calves under a year old, 
in which he could not detect “* worm nests’ whilst the animals were alive, 
His findings were all negative though the parasites were searched for in. 
a most careful manner.
