ratus. It is concluded from these experiments that the differences in results which 

 have thus far been recorded are due to slight differences in the operation of the st<?r-

Tick fever or murrain in southern cattle, J. C. Robert {Mississippi Sta. Bui. 

 73, pp. 24, figs. £). — In this bulletin the author presents a general account of Texas- 

 fever. Notes are given on the effect of water on the hatching of the eggs; the effect 

 of light and cold upon incubation; the effect of water, cold, and rainfall upon the' 

 ticks; the length of life of the ticks; the effect of small numbers and large numbers; 

 of ticks upon calves; the effect of a few ticks on cattle more than 12 months old^ 

 and the effect of large numbers of ticks on cattle jiast the age of 12 or 18 months^, 

 symptoms of Texas fever; post-mortem findings; relation of seasons of the year t&j 

 the disease; occurrence of Texas fever among southern cattle; method of vaccination! 

 against Texas fever; curative treatment; and immunization by infestation of young- 

 animals with ticks. The longest period in which the author has kept ticks alive- 

 without foo<l is 8 months. It is stated that there are many farms throughout Mis- 

 sissipi:)i on which no ticks occur, that ticks are never found in cultivated fields, in: 

 pastures and woods that have not been occupied by infested cattle for 12 months, or 

 on land which is annually washed by an overflow of water. A number of observa- 

 tions are recorded which show that immunity to Texas fever is not inherited, and 

 that consequently the calves of immune cattle must themselves be immunized in 

 order to acquire protection. Since it is considered an exceedingly difficult matter 

 to eradicate the cattle tick from the whole State, it is suggested that attention should 

 be given to infesting all young calves with a few ticks so as to render them immune- 

 and thus to protect the owner against subsequent loss from infection with Texas^ 

 fever. 



Clinical notes on cases of azoturia, haemoglobinuria, and acorn poisoning,. 

 E. J. Thorburn {Vet. Jour., n. set:, 5 {1902), No. 26, p)p. 102-106) .—\\\i\\ regard tO' 

 azoturia the author argues that much doubt still remains concerning the cause of the- 

 disease, the usual symptoms, and most effective treatment. In cases observed by 

 the author no change had recently been made in the feed, no period of rest preceded, 

 the attacks, and the distance which the horses had traveled before acute symptoms 

 developed were 10 to 18 miles rather than 1 or 2 miles, which is mentioned as the 

 usual distance in text-book treatment of this disease. While full doses of aloes are 

 usually given in treating azoturia, the author reports bad results from too large or 

 too frequent doses, and advises that some care be taken in administering this remedy. 



Notes are also given on a number of cases of hsemoglobinuria, with details on the- 

 conditions under which the disease occurred and the usual symptoms. In treating, 

 this disease it was recommended that animals first be removed from the place where 

 they became infected, and either put on different pasture or in the stable, according, 

 to the time of year. Full doses of purgatives should be ailministered, together with: 

 quinin and nux vomica in cases where loss of ai)petite is observed. f 



An unusual number of cases of acorn poisoning in cattle is reported. The symp- 

 toms are loss of appetite, grunting, i)rostration, and rapid emaciation, with a high, 

 temperature. In treating these cases of poisoning it is recommended that purgatives 

 V)e first administered, followed by stimulants and digestive tonics. 



On the actinomycosis-like development of some of the acid-resisting ba- 

 cilli, A. C. Abbott and N. Gildersleeve {Centbl. Bali. a. Par., 1. Aht., 31 {1902), 

 Xo. 12, Orig., pp. .347-550, pi. 1). — The observations of the authors are considered 

 as affording additional evidence in support of the belief that actinomyces, the 

 tubercle bacillus, and certain of the acid-resisting bacilli are closely related botan- 

 ically and should therefore be classified together from a morphological standpoint.. 

 The present paper is of a preliminary nature, and all the results of the authors' 

 investigations are not stated. The organisms which were studied included the grass^ 

 bacillus, timothy hay bacillus, and butter bacillus, as well as actinomyces and the
