^‘spotted’’ and no scab has since appeared. It seems probable 
that the sheep put into the pen were the cause of the one 
sheep that had been dipped with Zenoleum getting scab again. 
A Bunch of Sheep Dipped Twice in Zenoleum^ Diluted JjOO 
Times — On November 18, and again December 1, a bunch of forty 
sheep was dipped in Zenoleum diluted 400 times. No live 
scab appeared again until March 2, when one sheep with a 
small patch, less that an inch in diameter, was found. It is 
the only case that has appeared. This bunch had a good num- 
ber of very scabby sheep when dipped.

Applied to Sheep — On November 18, this dip was applied to 
forty sheep in the proportion recommended on the cans, which 
is three quarts in 200 gallons of water. There were a few cases 
of mild scab in this bunch, but no heavy scab. The treatment 
was not repeated and no scab has appeared since dipping. Fur- 
ther experiments are necessary before drawing definite con- 
clusions regarding this dip.
