ANALYSIS OF CONTINENTAL JOURNALS.

distinguish numerous corpuscles, offering the dimensions and 
appearance of grains of fine sand ; identical corpuscles were 
found in the bronchi leading to the patches, and the walls 
of these were thickened. A microscopical inspection showed 
that the corpuscles were perfectly circumscribed, and had 
the form of rounded clusters; on examining one of these 
spheroidal bodies, previously broken up, by the aid of a high 
magnifying power, it was easily seen that they were composed 
of extremely delicate corpuscles, to which they owed their 
granular aspect. Nearly all these corpuscles were animated 
by an active molecular movement, and those that were im- 
movable were enclosed by a gelatinous envelope in something 
the same way that the nucleus of a cell is by its protoplasm. 
In several of the recently incised patches there were also 
found, in addition to these corpuscles, a quantity of vegetable 
particles, fibrous and cellular in shape ; while the framework 
of the patches themselves was formed by pulmonary tissue 
infiltrated with pus. 
Dr. Bollinger, having made a special study of these pro- 
ductions, classes this peculiar pathological formation among 
the vegetable parasites grouped under the genera “ Zoogloca,” 
and proposes to designate it provisionally by the name of 
Zoogloca pulmonis equi. He considers the parasite, which he 
found in all the nodosities, as the primary cause of these, 
and believes that its germs, attached to vegetable matter in 
suspension in liquids, had been introduced into the ultimate 
bronchi and pulmonary alveoli; becoming developed and 
propagated in these situations, the Zoogloca had provoked 
and maintained a chronic inflammatory process, which 
brought about the destruction of the pulmonary structure, 
with partial substitution of cicatricial tissue. This morbid 
condition was named by the author “ pneumo-mycosis 
chronica.” * — Ibid., p. 847. 
* It may be remarked, with regard to this interesting case of pneumo- 
mycosis, that Heusinger (‘ Recherches de Pathologic Coinparee/ vol. ii, p. 
107 ) had, so early as 1821 , observed the presence of a vegetable “ mould” 
or fungus in the air-sacs of a stork, which had been found at Groningen — 
where it is rare to meet with these birds — by a peasant. When first dis- 
covered it was extremely feeble, and could scarcely drag itself along through 
the grass field in which it had alighted. It died during the same night, and 
was dissected a few hours after death. One of the ribs on the left side had 
been fractured immediately over the abdominal air-sac, and was united by a 
recently formed callus ; the abdominal air-sacs were red and indurated and 
did not collapse on being incised, but emitted an odour of new cheese ; their 
parietes were very thick, consisting of several lamellae, the external of which 
was the normal membrane, and the others false membranes ; the whole in- 
ternal surface of the two sacs was entirely covered by a fungus plant with 
loug filaments ; the large pectoral sacs appeared at the first glance to be
