Researches on the attachment of certain TJncinariae to the walls of the intes- 

 tines, A. Uiz'Ao {Atti. R. Accad. Lined. CI. Sri. Fis. M<il. c Xat., :> [1900), II, No. S, ])p. 

 107-115, figs. 2). — The author investigated the method of attachment and j)athological 

 effects caused by Uncinaria racliata and V. cernva. He found that tlie first species 

 produces a papilla in the walls of the intestines, at the expense of the submucous 

 connective tissue. The hooks and chitinous teeth with which the worm is provided 

 serve to lacerate the tissue of the intestinal wall. At the point of attachment a con- 

 stant inflammatory reaction is produced, but this effect is not very marked or of 

 great extension. The lesions produced by U. radiata are much more serious than 

 those caused by V. cmuia. 



Pathological conditions found in meat inspection, D. E. Salmon ( U. >S. Dept. 

 Agr., Bureau of Aniinal Industry lipt. 1900, pp. ry2-6-2). — This is an article which was 

 read at the meeting of the American Medical Association held in Atlantic City, N. J., 

 June 5 to 8, 1900. Detailed notes are presented on a number of cattle, sheep, and 

 hogs inspected by the Bureau of Animal Industry, the diseases which were discov- 

 ered during this inspection, and the number of cases condemned. During the 2 

 years from July 1, 1897, to June 30, 1899, 8,831,927 cattle were inspected. Of this 

 number 19,454 entire carcasses were condemned and 23,10(3 additional carcasses were 

 condemned in part. During the same period 11,110,776 sheep were inspected and 

 8,394 carcasses were wholly condemned; also 44,841,779 hogs were inspected, and 

 106,555 carcasses wholly condemned. Of the whole number of cattle carcasses 

 which were condemned 26 per cent were affected with actinomycosis and 36 per cent 

 with tuberculosis; and of those cases in which only parts of the carcass were con- 

 demned, 13 per cent were affected with actinomycosis and 1 per cent with tubercu- 

 losis. The beef cattle which are sent to large abattoirs are remarkably free from 

 tuberculosis, only 1 case in 1,500 or 2,000 being found by inspection for the 2 years. 

 Brief notes are given on a number of other diseases found during inspectioTi. >Special 

 mention may be made of pseudotuberculosis of sheep, nodular tfeniasis, and various 

 animal i)arasites, such as the common tapeworms in their larvel and adult stages, 

 the hydatid disease caused by echinococcus, and trichina. 



A practical guide to meat inspection, S. Stockman [Nnr York: Willinin. K. 

 Jenkins, 1902, pp. 295, ph. 14, figs. 79) . — This volume, pul^lished as the fourth edition 

 of the text-book of T. Walley, has been rewritten and somewhat enlarged Ijy the edi- 

 tor. The subjects which are discussed in the book include the historical development 

 of meat inspection, the method of inspection, general pathological conditions, post- 

 mortem changes in meat, inflammatory conditions, diseases of the blood, ))acterial 

 diseases, diseases caused ))y animal parasites, unclassed diseases, and food ])Oisoning 

 in man. A brief bibliography of the literature of meat inspection is appended to the 

 volume. 



Verminous diseases of cattle, sheep, and goats in Texas, C. AV. Stiles ( U. S. 

 Dept. Agr., Bureau of Animal Industry Rpt. 1900, ])p. 856-379). — An unusual outbreak 

 of disease due to parasitic worms occurred in certain parts of Texas and an investiga- 

 tion of the cause of the trouble was made by the author. The outbreak had already 

 been studied to some extent by Dr. W. Folsetter, and his report on the circumstances 

 of the outbreak, the post-mortem findings, and various treatments which were tried 

 is included in the present article. It was found upon investigation that the cattle 

 and sheep were attacked by a number of parasitic worms in the fourth stomach, 

 intestines, and bronchial tubes, or in all of these organs at the same time. In cattle 

 the fourth stomach was infested in a])out one-third of the cases with Strongylus con- 

 torlus; in some cases hundreds of the parasites were found in a single stomach. 

 S. ostertagi was found in all the cattle which were examined during the second 

 investigation of the matter. This species is smaller than <S'. eontortus and may be
