portion of the superior and inferior turbinated on the right side; 

 and lesions were also noted in lung tissue. Specimens of the af- 

 fected tissue were examined microscopically and disclosed the pres- 

 ence of bacilli mallei. 



Another outbreak took place near North English. An old family- 

 driving horse was found to have a well developed case of farcy 

 and glanders. By the consent of the owner it was killed. The sep- 

 tum nasi was ulcerated nearly its entire length, and at one place so 

 nearly eaten through that a straw was forced through it. The ani- 

 mal had apparently previously suffered from influenza and had 

 not fully recovered. Thorough disinfection was ordered, and the 

 balance of the horses on the premises, twelve in number, were quar- 

 antined. Another examination about a month later resulted in the 

 raising of the quarantine by this department. 



Horses at the large transfer barn at Iowa Falls became infected 

 recently. We recommended the destruction of two of them. On 

 post mortem they showed pronounced lesions. The remaining 

 twenty-nine horses on the premises were tested, a number reacting. 

 The entire number was quarantined. Another test was made sixty 

 days later, with the result that several horses reacted. One of them 

 was destroyed. These horses are still in quarantine. The source of 

 infection in this case was a horse shipped in from Dakota. 



Serious infection of glanders was discovered at Gillett's Grove 

 in Clay county, where four work horses belonging to a farmer were 

 affected. This farmer had immigrated from South Dakota with his 

 horses that year, one of them having slight nasal discharge at the 

 time he was shipped in, which was then supposed to be a symptom 

 of distemper. A considerable number of horses were exposed in 

 this case, but fortunately outside of the man's premises, no infec- 

 tion developed from the exposure. One of the four horses men- 

 tioned died and the remaining three were destroyed. 



A number of horses were driven through from western states 

 and held for sale at the livery and sales stable at Harcourt in "Web- 

 ster county, during the winter of 1909. At the time these animals 

 were bought, one of them had what was supposed to be distemper, 

 but what subsequently proved to be glanders. This horse was kept 

 in the barn mentioned during the winter of 1909. In the following 

 spring, he was sold to a farmer. Shortly thereafter he became very 

 sick and died. Upon investigation we found that a great many 

 horses had been exposed to this one, as the owners of the barn 

 bought and sold horses during the winter, besides stabling horses
