784 EXPEEIMENT STATION RECORD. 



found, and at autopsy none of the 10 cows was found to be very extensively 

 tuberculous." 



"At this station, 97 samples of feces from 62 tuberculous cattle have been 

 tested for tubercle bacilli by inoculation of guinea pigs. Tubercle bacilli were 

 found 4 times in samples from 3 animals." 



" In tbe circulating blood of tuberculous cattle, tubercle bacilli liave been 

 found by good investigators, but their occurrence here would appear to be 

 rather infrequent. In our own tests the results were wholly negative, but it 

 should be remembered that the cattle tested were not in an advanced stage of 

 tuberculosis." 



" There is a great need of extending the excellent sanitary regulations of some 

 of our large cities to the smaller cities and throughout the country generally. 

 A system of popular education concerning tuberculosis, the tuberculin test, 

 and health regulations would be of great benefit to the State." 



" For handling the tuberculous cow one of the following methods is advised : 

 (a) In advanced cases where there are physical signs of the disease or when 

 the cow is not very desirable for breeding or dairy purposes, slaughter under 

 inspection is best, (b) When it is desirable to keep the reacting cow for 

 the purposes mentioned above, the Bang method is recommended especially to 

 large stock owners, (c) For owners of smaller herds the modified Bang 

 method by means of a stock owners' association, so the tuberculous animals 

 may be farther removed from the healthy herd, is to be recommended." 



Elaborate bibliographies follow the discussions. 



Tuberculosis in the hog, S. Anderson (Maanedskr. Dyticeger, 21 (WW), 

 No. 24, pp. 651i, 655; abs. in Berlin. Tierarztl. Wchnschr., 26 (1910), No. 52, 

 p. 1053). — Out of a total of 64,G37 hogs examined in Odense, 3,039 were found 

 tubercular. The distribution of tuberculosis in the animal body was as 

 follows: In the lymphatic glands of the head, 1,121 cases; mesenteric glands, 

 882 ; head and mesenteric glands, 204 ; head, lungs, liver, and mesenteric glands, 

 358; head, lungs, liver, mesentery, and spleen, 45; head, lungs, and liver, 77; 

 head, lungs, pleura, and mesentery, 11; head, lungs, liver, mesentery, and flesh 

 glands, 100; head, lungs, liver, mesentery, and bones, 107; lungs, liver, and 

 mesentery, 4 ; lungs and mesentery, 4 ; lungs, 29 ; head and liver, 3 ; head and 

 lungs, 66; liver and mesentery, 9; lungs and liver, 4; head, liver, lungs, 

 mesentery, and central nervous system, 1. 



Experiments in connection with the treatment of cattle affected with 

 redwater, with trypanblue, and trypanred, S. Dodd (Yet. Jour., 66 (1910), No. 

 421, pp. 394-411). — The author reports experiments conducted in Queensland 

 to determine the value of these drugs in treating animals affected with viru- 

 lent strains of the piroplasm. 



He finds that while the injection of trypanred appears to have some effect 

 in destroying the parasites in the blood of an animal affected with piroplas- 

 mosis, its effect in reducing the temperature in severe cases is uncertain. The 

 effect of the drug in arresting the course of the disease in severe cases was 

 found to be slight, even when animals were treated early. He concludes that 

 the results obtained do not justify its further use in the field. 



The several series of experiments with trypanblue here reported show it 

 in the main to be an efficient remedy. " The most favorable results following 

 its use, however, are seen when it is injected at an early stage of the disease. 

 It may also be used with the anticipation of good results following when the 

 fever is at its height, but if the disease has been in existence several days, 

 not counting the period of inoculation — that is, the animal has been actually 

 ill for some days — favorable results must not be looked forward to with too 

 much confidence, for although, even in these cases, the-drug exerts an undoubted
