 praktiscli. Aerzte in St. Petersburg, 1842) found on dis- 

 section a Round-worm inserted in the vermiform process, 

 with its caudal extremity projecting into the crecum, 

 and he supposed that this worm, by its entering the ver- 

 miform process, had been the cause of the spasms, and 

 that after its death it had caused the diarrhoea as a conse- 

 quence of the fruitless efforts of the intestine to rid itself of 

 its deceased guest. Gilli (Schmidt's Jahrbiicher, Bd. 40, 

 1843, p. 310, from the Giornale clelle sc. med. March, 

 1842) observed in a child the discharge of 510 Round-worms 

 Avithin eight days. From the New York Journal of Medi- 

 cine it is related (Lancet, August, 1844, p. 589) that a man, 

 33 years of age, experienced excessive itching in the glans 

 penis, and unpleasant sensations in the rectum. Next day 

 difficult micturition supervened, and a long-shaped substance 

 gradually made its appearance from the urethra, which was 

 recognised by Clarke as a male Lumbricus teres, eleven inches 

 in length. To this Clarke adds, that the man had, eighteen 

 months before, suffered from dysuriawith discharge of blood 

 and pus, during which attacks the worm entered the bladder 

 from the rectum. The doctor considers it very remarkable 

 that the Lumbricus teres, " the common earth-worm," 

 should have reached the rectum. This betrays very great 

 ignorance of the human Entozoa, and the Reporter would 

 inquire whether the worm that was discharged should not 

 be referred to Strongylus (/if/as. 



Several new Nematoda have been described by Creplin 

 (Archiv, 1844, Bd. i, p. 115), but without his determining 

 their genus. They were found in the abdominal cavity and 

 the intestinal canal of Bradypus tridactylus, and Dipus 

 tetradactylus, the small intestine of Phacochoerus africanus, 

 the membrane on the bones of the fore-arm of Vespertilio 

 serotinus, the lungs of Coluber natrix, the stomach of Rana 

 dorsigera, the intestinal canal of Raja batis ; moreover, in 

 Sorex areneus, and Lepidopus Peronii, without the habitat 

 being more particularly stated. Several of these Entozoa
