The dissemination and action of the Pentastomum taenioides, S. von RAtz 

 {Allatorvosi Lapok, 3/f {1911), No, J^l, pp. JtSo-JfSS; abs. m Berlin. Tierdrztl. 

 Wchnschr., 28 {1912), No. 8, p. Ul; Vet. Rec, 24 {1912), No. 1236, pp. 582, 

 583). — The adult of P. twnioides lives in the nasal cavities of the dog, wolf, and 

 fox, and is also found in the same position in herbivora. " The larvje occur in 

 the thoracic and abdominal viscera, for the most part in the liver, lungs, and 

 mesenteric lymphatic glands, and are often found free in the pleural and peri- 

 toneal cavities of the hare, guinea pig, goat, sheep, horse, ox. pig, deer, cat, etc., 

 in addition to those of man. . . . The ripe ova pass out from the host's nose 

 on to plants, and with them into the stomach of (usually) herbivora. Here the 

 embryos, and later the larvae, penetrate the intestinal wall into the blood and 

 lymph vessels, and pass in these to the different organs, where the larva (for- 

 merly known as L. serrata or P. denticulatum) develops further. Afterwards it 

 becomes encysted or wanders farther into the serous cavities. The author's 

 results do not support the view formerly held of the active wanderings of the 

 Linguatulse in the bronchi. 



" Infection in carnivora occurs as follows : Cai*nivorous animals take up the 

 larvae of the parasite with the lungs, liver, etc., which they devour. The larvae 

 wander from the stomach through the esophagus into the mouth, and thence 

 into the nasal cavity. Moreover, when infected food is swallowed, single free 

 larvae may adhere to the palate and from there migrate into the nasal cavity. 

 Finally, the author has experimentally proved that animals may acquire young 

 Linguatulse in their nostrils by smelling at organs containing larvae. 



" When in the nasal cavities the parasite causes bleeding. More rarely it 

 occasions violent inflammation and nervous symptoms resembling those of 

 rabies." 



The diagnosis of rabies, J. Rmchel {Ann. Rpt. Penn. Dept. Agr., 16 {1910), 

 pp. 179-195). — The usual history, symptoms, gross appearance after death, 

 laboratory examination, animal inoculation test, microscopic examination, and 

 rules regulating the examination and diagnosis are considered. 



Investigations of and tick eradication in Rocky Mountain spotted fever, 

 T. B. McCliniic (P»6. Health and Mar. Hosp. 8eri7. U. 8., Puh. Health Bpts., 

 27 {1912), No. 20, pp. 732-760).— The work of eradicating the Rocky Mountain 

 spotted fever tick, conducted in cooperation with the State Board of Health of 

 Montana, was begim May 26, 1911, an infected territory of about 8 square 

 miles in the Bitter Root Valley, located about 3 miles from Victor, Mont., being 

 selected for the work. A concrete dipping vat was constructed and 116 horses, 

 199 cattle, and 108 sheep were dipped and 155 redipped. Some 3,465 small 

 wild animals, of which 3,233 were ground squirrels, were killed by shooting 

 and trapping, and in addition many were killed by poison or carbon bisulphid. 



" Out of a total of 4 badgers that were experimented with only 1 of them 

 was found susceptible to infection with si^otted fever, and of 5 guinea pigs 

 that were inoculated with blood taken from this badger at 3 different times 

 only 1 of them developed spotted fever. . . . The results with experiments of 

 infecting 5 coyotes and 4 domestic cats were negative. . . . Only 2 weasels 

 were experimented with, 1 of which was experimentally infected with spotted 

 fever while the results obtained in the case of the other were negative but 

 not conclusive." In a search made for the infection of spotted fever among 

 ground squirrels in nature the results were negative. 



" Rhesus monkeys and guinea pigs were infected with spotted fever and 

 treated with different drug preparations, namely, Salvarsan, sodium cacodylate,
