THE DISEASES OP SHEEP. 297 



If, in dosing, this liquid enters tlie lungs the 

 animal may succumb in a few minutes. If the 

 dosing is performed carefully, as much as 6 2-3 

 ounces may be given to a full-grown sheep 

 without fatal results. In some cases, however, 

 the animal shows ill effects, from which it usu- 

 ally recovers within half an hour. Six ounces 

 were given to a number of sheep without the 

 slightest ill effects. The following table gives 

 the doses of the 1 per cent mixture which were 

 used in about 400 cases without ill effects: 



Lambs 4 to 18 months old 2 to 4 ounces (about 60 to 120 c. c. ) 



Yearling sheep and above 3 to 5 ounces (about 90 to 150 o. o.) 



Calves 3 to 8 months old B to 10 ounces (about 150 to 300 c. o.) 



Yearling steers 1 pint (about 480 c. c.) 



Two-year-olds and above 1 quart (about 960 o. c.) 



Sheep, goats, and calves which received this 

 treatment .^showed a marked Lmprovement a 

 few days after receiving a single dose. 



In experiments, with creosote at Washing- 

 ton, D. C, sheep were drenched with a 1 per 

 cent solution and killed immediately after- 

 wards. Upon opening the fourth stomach, it 

 was found that the wireworms present were 

 dead. In some cases where this was tried later, 

 the wireworms were found to be still alive; but 

 it is believed that the explanation of this fact 

 has now been discovered, as will later be seen. 

 Creosote does not appear to have much effect 

 upon the worms below the stomach. 



If an overdose is given by, mistake, and if 

 the sheep appears severely affected by it, the 

 animal should be placed in the shade. Even in 

 some cases of very severe overdoses, where the
