(luced witliiii a few iiiinntes. The location of tlu- chief lesions of the disease differed 

 strikinjily from tliat of previous outbreaks. In other epizootic outbreaks of this dis- 

 ease pneumonia an<l intiammation of the serous membranes were the chief symp- 

 toms, whereas in the outbreak under consideration the lesions were chiefly confined 

 to the alimentary tract. The pathogenic bacillus was isolated in all cases and believed 

 to be the same. 



Quite extensive studies were made on tuberculosis of cattle (pp. 159-162). Herds 

 were tested with tuberculin, and a large number of animals were subjected to careful 

 clinical examination for the purpose of determining more accurately the physical 

 symptoms of the disease. The post-mortem findings of 200 cattle condemned for 

 tuberculosis and destroyed are summarized in tabular form. 



The author discusses the reeults of the inspection of meat in slaughterhouses, the 

 subject of compensation for condemned animals, the inspection o'f dairy cattle on the 

 premises, veterinary education, bacteriological examination of dairy products, and 

 malignant cancerous growths in domestic animals. 



The nature and cause of the "bush" disease of cattle and sheep is considered (pp. 

 186-189). The i)ost-mortem examination of animals dead of this disease indicated a 

 condition of ansemia, with a fatty degeneration of the liver, but no other organic 

 lesion. In some cases in sheep the animals became much emaciated and dropsical. 

 A few specimens of Strongylus contortus Avere found in the stomach of sheej), but not 

 enough to have been responsible for the symptoms. The author believes that the 

 best treatment for this disease consists in a radical change of feed. The exact nature 

 of the trouble remains doubtful. 



Brief notes are given on Strongylus eerricnrmia in calves, on red water of cows, 

 strangles in horses, hepatic cirrhosis in horses and cattle, and S. tentracanfhiut in 

 horses. 



A number of outbreaks of malignant (edema in sheep and lambs are reported (pp. 

 194-197). Tills disease occurs chiefly after shearing sheep and docking lambs. 

 Experiments were made for the purpose of determining the means whereby infection 

 is spread. A small quantity of soil was taken from an infected locality and a1)out 

 5 gm. was dissolved in 5 cc. sterilized water. After a sediment had formed, the 

 muddy colored liquid was used for inoculating a 3-months-old lamb. The lamb 

 became stiff in the inoculated leg after 24 hours; later the flank was swollen and 

 sensitive to the touch. Death occurred 56 hours after inoculation. Three species of 

 bacilli were isolated from the blood of this animal, 2 being aerobic and 1 anaerobic. 

 Inoculations of pure cultures of the anaerobic bacillus produced marked cases of 

 malignant oedema. For preventing the spread of this disease the author recom- 

 mends the removal of surface soil of infected yards, which should be placed in a heap 

 where it can thoroughly be mixed with quicklime. The fresh surface should then 

 be treated with strong and cheap antiseptics. In shearing sheep or docking lambs 

 it is imperative that all wounds should be immediately treated with some antiseptic 

 such as car])olized oil. 



The author investigated a disease of sheep called suppurative pleurisy and pneu- 

 monia (pp. 197-200). An extensive outbreak of this disease occurred in lambs soon 

 after dipping. Post-mortem examination of dead animals showed marked changes 

 in the pericardium. It was distended by the accumulation of a large quantity of 

 serous fluid, and the whole surface was covered by a fibrinous deposit J in. in thick- 

 ness. Affected animals held the head extended and slightly to one side, and the 

 gate was unsteady, with a distinct tendency to fall upon the left side. A detailed 

 description is given of a micro-organism which was found in the fibrinous pus. Pure 

 cultures were made and the disease was reproduced by means of inoculation of 

 lambs. 



Brief notes are given on acute facial eczema in sheep, which is believed to be due 

 to eating rape in excessive quantities. A disease among quail recently imported
