412 EXPERIMENT STATION RECORD, 



liungworms in swine, C. J'\ Dawson {Mo. Bnl. Floritht Dipt. Aijr., l.J (1903), 

 No. 83, pp. 66, 67). — A study of an outbreak of a fatal disease in pigs revealed the 

 fact that the disease Avas due to the presence of a lungworm, Strougylus parado.rn.^. 

 The disease is locally known in Florida as thumps. Young animals are more susce])- 

 tible than older ones. The symptoms vary according to the number of worms pres- 

 ent. The method of treatment recommended by the author is that of fumigation 

 with irritating substances for the purj)0.se of causing the expulsion of the worms ])y 

 coughing. 



The etiology of heaves, W. L. Williams {Ayner. Vet. Rec, 26 {190.1), No. 10, pp. 

 95.5-!).57). — While veterinarians are generally agreed that musty clover and timothy 

 hay, esi^ecially if cut very ripe, are the usual cause of this disease, the author calls 

 attention to the fact that the animals recover when proper care is taken of the diet. 

 The fact is cited that clover and timothy raised under a system of irrigation never 

 cause heaves, even if these crops are allowed to become very ripe before cutting. 

 The author believes that it is possible that heaves may be due to some parasitic 

 organism which is developed upon the feed in the field under certain conditions. 



Purpura haemorrhagica, J. W. Cook {Amer. Vet. Rev., 27 {1903), No. 3, pp. 209- 

 212). — In treating cases of this disease in the horse the author reports satisfactory 

 results from making numerous deep incisions in the various swellings which appear 

 during the progress of the disease. This remedy led to recovery in all except 1 case. 



Cerebro-spinal meningitis, B. K. Dow {Amer. Vei. Rev., 27 {1903), No. 6, pp. 

 515-521). — A general account of the cause and treatment of this disease. Notes are 

 given on the treatment of cases in the horse. Strychnin, ginger, and belladona were 

 administered without noteworthy beneficial effects. 



Biliary fever or malarial fever in the horse, A. Theiler ( Traitsraal Agr. .Tour., 

 1 {1903), No. 3, jjp. 11-14)- — This disease has long been known in South Africa, and 

 its name is due to certain of the most conspicuous symptoms. It resembles Texas 

 fever in cattle and is not contagious. The disease occurs in a chronic and acute 

 form. Notes are given on the differential diagnosis of this disease. One of the most 

 con.spicuous post-mortem appearances is a brownish-yellow discoloration of the nuiscle 

 tissue. Recovery from one attack apjjears to confer immunity in the majority of 

 cases. 



Ulcerative enteritis in the horse, G. L. Buffington {Amer. Vet. Rev., 27 {1903), 

 No. 2, pp. 124-128). — The author describes the symptoms of this disease and outlines 

 the conditions under which it occurs. Ulcerative enteritis runs a course of from 1 

 to 3 days and is fatal in a large percentage of cases. When the form of the disease 

 is not too acute some benefit is derived from the administration of gentian powder, 

 subnitrate of bismuth, prepared chalk, potassium chlorate, and powdered ginger. 



Some facts and theories regarding surra and ulcerative lymphangitis, C. 

 NocKOLDS {Amer. Vet. Rev., 27 {1903), No. 2, pp. 129-131).— In the Philippines surra 

 appears to be a rainy weather disease and persists for from 4 to 6 weeks after the 

 dry season begins. The disease still prevails greatly in the Philippines and is the 

 cause of enormous losses in horses. Brief notes are given on the possible agency of 

 insects in carrying the disease. Ulcerative lymphangitis is said to be on the increase. 

 More cases occur during the wet season than during the dry season. This disease 

 appears to be caused by an organism which gains entrance in wounds. 



The tsetse-fly disease and other related diseases, C. Schilling {Arch. Schiffs 

 ?«. Tropen-Hi/(j., 7 {1903), No. G, pp. 255-262). — Notes on the nature and cause of 

 various diseases of animals and man due to infection with species of Trypanosoma. 



The action of human serum on the Trypanosoma of nagana, mal de 

 caderas, and surra, A. Laveran {Compt. Rend. Acad. Sci. Paris, 137 {1903), No. 1, 

 pp. 15-19). — Human serum when injected into animals infected with nagana has 

 already been shown by the author to be very effective in destroying the blood j)arasite.
