Croup in cows, P. Grunth I Maanedsskr. Dyrlseger, 16 I 1904 • No. .'. pp. 33-47). — 

 The symptoms of this disease as observed by the author in various parte of Denmark 

 are essentially those of bronchitis, combined with evidence of infection of other 

 :ous surfaces, especially of the reproductive organs. In 42 per cent of the cases 

 the lungs were affected, while in itJ'! per cent of the cases both the lungs and uterine 

 membranes were involved. The disease appears to assume the form of a general 

 catarrh. 



Osteomalacia in cows, .1. Hoyem (Maanedsskr. Dyrlseger, l>; (1904), No. 5, pp. 

 151-157). — The symptoms of this disease are described in connection with notes on 

 its distribution and etiology. In general the prognosis in cases of this disease are 

 not favorable. Wherever the trouble appears the soil or feeding stuffs should be 

 suspected as being deficient in mineral elements, and lime and phosphate should he 

 added to the ration by way of treatment. 



Bloody milk in cows, Poscu I Deut. Tierarzll. Wchnschr., 12 (1904), No. 43, pp. 

 431,482). — in the author's opinion bloody milk in cows occurs much more fre- 

 quently than is generally supposed. Jt is believed that a number of cases fail to be 

 observed since the trouble persists only a short time after calving. In 2 cases which 

 were studied by the author the disease could not be attributed to any injurious 

 properties in feeding stuffs nor to inflammation of the udder. The cause of the 

 trouble was. therefore, to be sought in general congestion. 



A verminous disease of calves in the districts of Tegernsee and Miesbach, 

 G asteiger (Monatsh. Prakt. Tierh., JO (1904), No. /-•/, pp. 49-92).— The literature 

 bearing on this subject is discussed in a critical manner. 



The author had opportunity to study a number of outbreaks of this disease and 

 detailed clinical notes are given on the progress of the disease in numerous cases. It 

 was found as a result of these studies that in portions of Bavaria a verminous disease 

 of an epizootic character prevails in sucking calves. The cause of the disease is 

 Ascaris lumbricoides. The e^gs of this worm are not found in the drinking water or 

 in the feces of the cows. They are found, however, in large numbers in the bedding 

 and about the stalls. 



Calves become affected during the first few days after birth and apparently by 

 direct ingestion of eggs which develop without an intermediate host. The disease 

 appears most widespread at the age of 3 to 5 weeks. Notes are given on the symp- 

 toms, pathological anatomy, and diagnosis of the disease. Considerable benefit was 

 derived from administering tartarus stibiatus, areca nut, and Mores cinae. As a pro- 

 phylactic measure the author recommends that the feces of infected calves be burned 

 and that strict disinfectant measures be put in operation. 



Cattle poisoning by " Klimop " ( Cynoctomum capense), D. Hutcheon 

 (Agr. Jour, Cape Good Hope, 25 (1904), No. 4, pp. 398-401). — A number of the cattle 

 are reported as having been fatally poisoned by eating this plant. Feeding experi- 

 ments with sheep indicated that from 1 to 2 lbs. of the plant are required to produce 

 serious symptoms in an animal weighing 100 lbs. Decoctions of the leaves and 

 stalks did not prove poisonous unless used in large quantities. 



When animals are poisoned by this plant they show characteristic symptoms of 

 spasms, which recur at frequent intervals. No specific is known against this form 

 of poisoning. The author recommends the administration of purgatives to remove 

 any unabsorbed portion of the poisonous plant and of chloral hydrate in combating 

 the symptoms. 



Researches in helminthology and parasitology, J. Leidy I Smilhsn. Misc. 

 Collect., 46, No. 1477, pp. 1-281). — The numerous publications of Professor Leidy 

 relating to animal parasites are presented in this volume in the form of abstracts 

 which have been arranged and edited by J. Leidy, jr. A bibliography of the publi- 

 cations of Professor Leidy is appended to the volume.
