 to impossible to disinfect satisfactorily and thoroughly. 



Post-Mortem Examinations. 



During the month a number of post-mortem examinations were 

 made, the results of which are as follows : 



Three cows condemned at K. Yamashita's dairy, April 29, 

 1916: 



No. 1 — Retropharyngeal glands and one prescapular gland 

 affected. 



No. 2 — Small nodules in lung and mediastinal glands ; two 

 mesenteric glands and one portal gland. 



No. 3 — Retropharyngeal glands affected. 



Two condemned cows slaughtered at the C. & L. Meat Co.'s 

 abattoir : 



No. 1 — Large nodule in left lung; nodules in both bronchial 

 and mediastinal glands. 



No. 2 — Old calcereous nodules in diaphragmatic lobe of left 

 lung; recent nodules in diaphragmatic lobe of right lung and 

 mediastinal glands. 



Six condemned cows slaughtered at the Waialae abattoir : 



No. 1 — Numerous recent nodules in the mediastinal glands. 



No. 2 — Recent nodules in bronchial and mediastinal glands. 



No. 3 — Recent nodules in retropharyngeal glands. 



No. A — Bronchial and mediastinal glands affected ; every evi- 

 dence of recent infection. 



No. 5 — Bronchial and mediastinal glands and numerous nod- 

 ules in both lungs. 



No. 6 — Recent nodules in mediastinal glands. 



Besides the above, a few pathological specimens were received 

 from the Metropolitan Meat Co.'s abattoir, taken from the lungs 

 and costal and diaphragmatic pleurae of a Molokai steer. A 

 diagnosis of tuberculosis was made, which was fully substanti- 

 ated by a careful microscopical examination. 



Hog Cholera. 



During the past month two outbreaks of hog cholera were 

 reported. The prompt application of anti-hog cholera serum cut 

 the loss to practically nothing, as in one herd only three small" 

 pigs were lost and in the other two medium-sized ones died. A 

 total of 58 hogs were injected. The advantages of the prompt 

 injection of serum in herds in which the disease has made its 

 appearance can hardly be overestimated. 



Chicken-pox or Sorehead. 



During the month 10.162 gms. of powdered virus of different
