Bang's disease may exist, then positive reaction with the intradermal abortin 

 test in several animals would show that the suspicion is well founded, whereas 

 uniformly negative results would tend to indicate that the infection was not 

 present. 



" Outside of clinical observations, including the history of the herd and 

 deductions made of material aborted, the veterinarian must rely on the results 

 of tests that include laboratory procedures, the results of which as a rule are 

 very difficult to interpret. . . . When the results of the bacteriological or 

 serological tests are available the results of the intradermal abortin test can 

 be used as additional confirmation, and if circumstances prevail where bac- 

 teriological or serological tests can not be made then the intradermal abortin 

 test can serve as an additional means or procedure open to the veterinarian in 

 practice." 



Formalin in the treatment of mastitis, J. N. Feost {Jour. Amer. Vet. Med. 

 Assoc, 51 (1917), No. 1, pp. 85-88). — The author reports having obtained 

 gratifying results from the administration of formalin by mouth in the treat- 

 ment of infectious mastitis. In his experiments 25 cc. of formalin given to a 

 cow undiluted in capsules twice daily for two weeks failed to produce ill effects 

 in any way, either by loss of appetite, constipation, or emaciation. Fifty cc. 

 was also given at one time without ill effect. Five cases of mastitis cui'ed by 

 this treatment are reported. 



When one dram of formalin was given faint traces could be found in the 

 milk in 24 hours. When 25 cc. was given three hours after water and seven 

 hours after milking it was found in the milk two hours afterwards and con- 

 tinued to be present for 48 hours. 



Eradication of the cattle tick in Argentina, A. Ayerza, F. Sivobi Brr al. 

 (An. Soc. Rural Argentina, 50 {1016), No. 6, pp. 582-584).— A pl'in for the 

 eradication of the cattle tick in Argentina, prepared by a commission ap- 

 pointed by the Minister of Agi-iculture, is presented. 



iTotes on a fatal parasitic infestation in a herd of cattle and goats in the 

 Province of Ambos Camarines, W. H. Boynton and L. D. Whaeton {Philip- 

 pine Agr. Rev. [English Ed.], 9 {1916), No. 4, pp. 3^8-353 ).—This.paper reports 

 upon the occurrence in the Province of Ambos Camarines of helminths in cattle 

 and goats which had succumbed to their attack. The helminths dealt with are 

 Bunostomum plUebotomum, OSsophagostomum columbianum, QJ^sophagostovium 

 sp., Hwmonchus contm-tus, Trichuris ovis, Filaria labiato-papillosa, nematode 

 species, and Paramphistomujn sp. 



Louping-ill, S. Stockman {Jour. Compar. Path, and Ther., 29 {1916), No. 3, 

 pp. 244-264). — This article, which deals particularly with the possibility of 

 the transmission of this disease by ticks, includes reports of experiments in 

 which the tick theory was tested. 



" The experimental evidence so far is against the view that louping-ill is 

 a disease carried by ticks. There still remains to be tested by direct experi- 

 ment, however, the possibility of ticks acquiring infection when sucking as 

 larvae, remaining noninfective in the nymphal stage, and developing infectivity 

 when adults." 



The author concludes that until the experiments now being carried out have 

 been completed it will be unwise to conclude that louping-ill is not a tick- 

 borne disease. 



Boundworms of sheep, B. H. Ransom (f7. S. Dept. Agr. Rpts. 1916, pp. 121- 

 ISO). — During 1915 nematode experiments were made at Vienna, Va., with 

 approximately 100 ewes and lambs separated into four lots. The first lot was 

 kept continuously on the same pasture from May to September. The second 

 lot was kept on a double pasture from May to September, grazing alternately
