contained in t^iu-h kidnoys, ami it is concluded that the white spots in these kidneys 

 are embryonic tissue which has not undergone the usual nioditications. Affected 

 kidneys are not only harudess, but tests indicate that the flavor of spijtted kidneys 

 is better than that of normal kidneys. 



Salt sickness, H. E. STocKHiunGE (Florida Sta. Rpt. 1901, pp. 43-54, ph. 4). — For 

 a number of years complaints were made of the prevalence of a disease known as 

 "salt sickness" in various parts of the State. The subject was investigated by the 

 author, in connection with W. E. French and J. E. Ennis. As the result of these 

 investigations it was found that so-called salt sickness was not a disease, but merely 

 a condition of starvation due to animals being confined on poor i)asture, consisting 

 of dry wire grass and other inferior vegetation. When the animals Avere properly 

 fed or changed to good range or pasture they uniforndy rei-overed. 



Lead ore in sugar-beet pulp, J. A. Widt.soe and L. A. Merrill ( Vlnli Stn. Bui. 74, 

 pp. 5-5->J2). — Complaints having been made at the station concerning disease and death 

 among cattle eating sugar-beet pulp, an investigation of the subject was made with 

 the result that the trouble was found to be due to lead ore in the pulp. The freight 

 cars in which tlie sugar-beet pul^j was shipped had been previously used for trans- 

 porting lead ore and had not been cleaned. As a result sufficient quantities of ttie 

 lead ore were shoveled out along with the pulp to cause the death of a number of 

 cattle. The material which was found in the sugar-beet pulp proved on analysis to 

 be mainly sulphid of lead with an admixture of sulphid of injn. A faint trace of 

 rasenic was also present, but no copper or other poisonous metals were found. The 

 symptoms of the animals poi-soned with these substances are descril)ed. Affected 

 cattle first refused to drink, then withdrew from the herd and laid down with the 

 head drawn toward the flank. Constipation was uniformly present. There was loss 

 of control of the voluntary muscles and an increased quantity of saliva was observed. 

 The mineral substances already mentioned were found lodged against the sides of 

 the stomachs on post-mortem examination. Three ounces of lead ore were obtamed 

 from a piece of the first stomach 6 in. square. The desirability of having freight 

 cars cleaned before being loaded with sugar-beet pulp is suggested. As treatment 

 for lea<l jioisoning large doses of Epsom salts (2 lbs. per animal) are reconnnended. 

 When symptoms of recovery appear iodid of potash may l)e given in 2-dram doses 

 3 times per day for the period of a week. 



The work against sheep scab, D. E. Salmon ( L'. Fi. Dept. Agr., Bureau of Animal 

 Iitdudrij Rpl. IDOO, pp. 69-S6). — The author gives a copy of an order of the Bureau of 

 Animal Industry concerning the dipping of sheep which are affected with sheep 

 scab. In order to make the work against sheep scab more thorough and effective 

 special sheej) inspectors were stationed at various points where greatest demand was 

 made for dipping diseased sheep. Details are given in tabular form concerning the 

 number of sheep dipped in various locations and the effectiveness of the treatment. 

 Of 515,112 sheep subjected to only one dipping, 86 per cent were cured and 14 per 

 cent remained infested with the scab mite. Three dipping solutions were used in 

 treatment for scab, viz, nicotin and sulphur; extract of tobacco and sulphur; and 

 lime and sulphur, prepared according to the fonnula of the Bureau of Animal Indus- 

 try. All these dips proved to be about e(iually effective. 



The treatment of sheep scab, Regenbogex [Berlin. Thieriirzfl. WcltuncJir., 1001, 

 No. 3S, ]>p. 50i-.5a?).— Statistics are presented showing the great prevalence of sheep 

 seal) in different parts of Germany since the year 1879. The methods which have 

 been recommended for treating the disease are considered as defective in many par- 

 ticulars. In general, 2 forms of treatment have Ijeen adopted — the hand treat- 

 ment ])y smearnig insectici<le substances upon scab areas, and complete dipjiing mto 

 an in.^^ecticide su])stance. The author exjierimented with a proprietary substance 

 sold under the name of "Akaj)rin." This substance in a 4 i)er cent solution with 

 water at a temperature of 30° C destroys the scab mites in one dipping of from 4 to
