oxen and sheep in excessive salivation. Tlie pulse and respirations were only 

 increased in old-standing cases. There was no fever and the sensorium did not 

 appear to be affected. Occasionally animals recovered after a very long period 

 of convalescence. 



In post-mortem examination no visible pathological changes could be detected 

 with the naked eye. Bacteriological examinations of the various organs ap- 

 peared to indicate that the cases were due not to an infection but to an intoxi- 

 cation. Examination of the materials sent revealed the presence in greater or 

 less quauiities of cadaveric bacilli in all organs. The streptococci or other 

 micro-organisms described by Schlegel, which are generally easy to discover, 

 could not be detected in the interior of any of the organs. From inquiries it 

 was found that during the previous year the grain of Essesdorf had been se- 

 verely attacked by fungi. Microscopic examinations of the black mycelium 

 showed that it was a form of Piiccinin graininis. 



An outbreak of poisoning from infected brawn, "W. G. Savage and C. H. 

 GuNSON (Jour. Hyg. [Camhridye], 8 {1908), 'So. 5, pp. 60i-608).—" Eighteen 

 persons after eating a. certain batch of pork-cheese, or vegetables infected from 

 it, suffered from severe illness and three died. The illness was caused by a 

 Gaertner bacillus of the Aertrycke subgroup isolated from one of the fatal 

 cases. This bacillus was contained in the meat used for the pork-cheeses 

 (brawn), infection being antecedent to preparation. Part of the meat was ob- 

 tained from a pig suffering from local injury or disease of one leg and the 

 bacilli were no doubt etiologically connected with this condition. The outbreak 

 points to the need for a more complete and thorough veterinary inspection of 

 meat before sale, and of tlie necessity for extended investigation into the dis- 

 eases of animals used for human food caused by Gaertner bacilli." 



Tetanus or " lockjaw," X. S. Mayo and E. L. Luaces (Estac. Cent. Agron. 

 Cuba Circ. 31, English Ed., pp. 11, pi. 1, figs. 2). — An account is given of the 

 cause and nature of tetanus. The disease is said to be very common in Cuba 

 and to cause serious losses of horses and mules. Preventive measures and 

 remedies are discussed. 



Tuberculosis of the retropharyng'eal lymphatic glands in cattle, L. Spartz 

 {Hyg. Viatide ct Lait, 2 (1908), Xo. 6, pp. 2Jtl-2Jf3) .—An account by the director 

 of the abattoir at Luxemburg. 



Tuberculosis of these glands is found very often in animals slightly affected 

 with pulmonary tuberculosis and occasionally when lesions can not be found in 

 any other part of the body. Of 28 animals which during the last 5 months of 

 1907 were found to present lesions of the retropharyngeal glands, 7 showed no 

 lesion elsewhere. This disease is generally local, the bacilli having penetrated 

 directly by the lymphatics of the pharynx and not in consequence of a gener- 

 alization by the blood stream. When the glands become tuberculous they 

 increase in size and cause continuous irritation, the action upon the pharynx 

 resembling that of a foreign body. 



The author has never seen either cutaneous, osseous, or muscular tubercu- 

 losis in the head. 



The nature and control of bovine tuberculosis, Y. A. Moore {Vt. Bd. 

 Health Bui., 9 {1908), Xo. 2, pp. 12-29).— The "nosing" of heaithy cattle with, 

 infected animals and their feeding and drinking after them are stated to be 

 the most usual methods of contracting the disease. There is no evidence that 

 in cattle tuberculin excites a latent tubercle into activity or that it tends to 

 make the disease worse. 



For the eradication of the disease it is important that the dairyman have a 

 source from which he can obtain sound animals. Three procedures from which 

 to choose in eradication are, (1) the total destruction of the infected animals,
