Miscellaneous. 171 



account of contagious peripneumonia, M. Bugnion only ascertained 

 fourteen cases of the latter disease in 170 head of cattle, while at 

 least sixty (for the most part young animals) were affected with 

 verminous pneumonia. This had a strongly marked lobular cha- 

 racter and appeared throughout to be of recent date. On cutting 

 into the bronchi, great numbers of filiform worms {Strongylus 

 micrurus), measuring as much as three inches long, were to be 

 found, generally coiled up in an accumulation of yellowish mucus. 

 The bronchi occupied by the parasites are precisely those which 

 correspond with the hepatized lobules. 



The diffused form was observed in goats at the Veterinary College at 

 Zurich. In one of these animals which died on the 22nd of May, 

 1875, the lungs no longer contained any adult Stronr/i/U ; but there 

 were thousands of elongated ova about one tenth of a millimetre in 

 length, and a great number of little worms very like Trichimv and in- 

 visible to the naked eye. These little parasites irritate the pulmonary ■ 

 tissue like so many foreign bodies, and cause a sort of diffused in- 

 filtration which is generally of great extent. The microscope shows 

 considerable desquamation and proliferation of the endothelium of 

 the air-cells, as observed by Prof. Bollinger (" Zur Kenntniss der 

 desquamativen und kasigen Pneumonic," Arch, fiir exp. Path, und 

 Pharm. Bd. i. 1873). The Strongylus of the cow is expelled from 

 the lungs before oviposition takes place, and the young are developed 

 elsewhere ; but that of the goat (/S. Jilaria or rufescens ?) deposits 

 its ova in the lung, and it is in that organ that the young larva 

 passes through at least the first phases of its existence. Instead of 

 disappearing in the winter without leaving any traces, this ver- 

 minous pneumonia of the goat thus becomes a very serious chronic 

 disease. 



The author has studied the nodular form in a cat poisoned with 

 strychnine. All the lobes of the lung presented, both at the surface 

 and in the interior, a great number of perfectly circumscribed whitish 

 tumours, in each of which the microscope revealed a myriad of rounded 

 ova containing small rolled-up worms, embryos, or vitelline masses 

 in all stages of segmentation. Here, again, these little foreign bodies, 

 forming numerous colonies in the interior of the pulmonary tissue, 

 had caused a most distinct desquamative pneumonia, although re- 

 stricted to certain perfectly circumscribed parts. This observation 

 in every respect confirms that of Henle upon which Leuckart threw 

 doubt (' Die menschlichen Parasiten,' ii. p. 104), Other identical 

 cases have been reported by Legros (Gaz. Med., Paris, 1867, p. 131), 

 Villemin (Recueil de Med. Vet. 1867, p. 75), and Colin (Ann. de 

 Med. Vet., Brussels, 1867, p. 12). Similar nodosities also occur in 

 the lungs of the goat, sheep, and pig. These animals present some- 

 times the diffused pneumonia, at others the small pseudo-tubercular 

 tumours, according as the ova of Nematodes are scattered here and 

 there or united in colonies at particular points. — Blbl. Univ., Archives
