According to Alessandrini (Isis, 1843, p. 530) the Filaria 

 attenuata, from Ardea purpurea, is viviparous, whilst another 

 Ft/aria, under the cutis of Mustela foina, is oviparous. A 

 Filaria papiUosa, in the anterior chamber of the eye in a 

 Horse of the Moldavian race, was observed by Flogel. 

 (Oesterreichische medizinische Wochenschrift, 1843, p. 63.) 

 The horse's cornea at first appeared clouded, and sight was 

 lost in the right eye. After the cornea had been somewhat 

 cleared by the application of red precipitate ointment, a very 

 active worm, of the thickness of a strong linen thread, and 

 from two to three inches long, was, for the first time, 

 noticed. On the application of a brighter light it became 

 quiet ; subsequently, when the opacity of the cornea was in 

 great measure removed, a fold of linen dipped in hartshorn- 

 oil (Hirschhorn 61) was laid over the eye, which appeared to 

 affect the worm disagreeably, and after a few days to kill it. 

 Flogel mentions, as the predisposing cause for the origin of 

 this worm, the alteration in the habits of the horse, which, 

 having always enjoyed full liberty in its native country, 

 had been compelled to pass, during the last eight months, 

 the greater part of the day in a dark stall. 



Bouche (Entomologische Zeituug, 1844, p. 205), in dis- 

 secting several species of Gamasus, particularly Gam. coleop- 

 tratorum, margiuatus, horticola, &c., sometimes observed 

 Filuria, half an inch long, creep out from them, and move 

 about in the water for from twelve to twenty-four hours. 

 Bellinghani (Annals of Nat. Hist, xiv, p. 475), besides 

 Filaria attenuata in the cellular membrane of the abdomen 

 of Falco peregrinus, and two new Filarue found in the 

 peritoneum of Trigla Pini and Mugil capito, has also 

 remarked in the abdominal cavity of Bombus terrestris on 

 several occasions numerous minute cylindrical filaria-like 

 worms. A Filaria, thirty inches long, which inhabits the 

 abdominal cavity of the Rhea nmericana, is mentioned by 

 Owen. (Lectures on Comparative Anatomy, p. 74.)
