vesicular emphysema

Pathol.: The enlargement of the air-cells of the lungs, followed by the perforation of their alleg as to produce small oval openings, ultimately enlarging. Called also Pulmonary Emphysema. vě-sic-u-late, adj. [Latin vesicula a vesicle; Eng. adj. suff. -ate.] Full of vesicles or small bladders; vesicular. vě-sic-u-lif-er-i, subst . pl . [Lat. vesicula =a vesicle, and fero to bear. Named from the small globose, transparent sac in which the spores are first enclosed.] Bot.: The same as PHYSOMYCETES (q. v.). *vě-sic-u-lō-są, s . pl . [Neut. pl. of Lat. vesicu los us.] [VESICULOSE.] Entom.: A tribe of Diptera created by Latreille. It was equivalent to Leach's family Acroceride. There are two genera, Acrocera (=Syrphus, in part) and Henops (=Ogcodes), both composed of small insects, having the abdomen much swollen. Species few in number, chiefly exotic; found upon plants and among flowers. vě-sic-u-lōse, vě-sic'-u-loŭs, adj . [Lat. vesic ulosus , from vesicula =a vesicle (q. v.); Fr. vésicu leux .) Pertaining to or of the nature of vesicles; vesicular. IMG:content-0480.png:[blocks in formation] vespertilio (q.v.).] Zool .: A group of Vesper til i on ide, with eight genera, having the range of the family. Nostrils simple, opening by crescentic or circular apertures at the extremity of the muzzle; ears generally moderate; forehead not grooved. věs-per-til-1-ō-ni-dæ, s. pl. [Mod. Lat. vesper tilio, gen it. vesper til i on (is); Lat. fem. pl. adj. suff. -idœ.] 1. Zool .: A family of Micro chiropter a, with three groups (Plecoti, Vesper til i ones, and Mini opter a), generally distributed throughout the temperate and tropical regions of both hemispheres. They are easily distinguished from all other bats by their simple nostrils at the extremity of the conical, somewhat elongated muzzle, by the long tail pro duced to the hinder margin of the large interfemoral membrane, and by the upper incisor teeth, which are separated by a wide space, and placed vest II. Geology: The term applied to the thirteenth series of the Appal a chi an strata, equivalent to the lowest Carboniferous group of Europe. The maxi mum thickne in Pennsylvania exceeds 2,000 feet. ( Prof. H. D. Rogers: Geology of Pennsylvania. ) věs-per-ū-gō, s. [Lat.=a bat, from vesper us = evening.] Zool .: A genus of Vesper til i ones, with twenty-two species, universally distributed, but more common in the temperate and subtropical regions of the eastern hemisphere. This genus has also the most northernly range of the Chiropter a, one species Vesperugo borealis -having been found close to the limits of the Arctic Circle. The Bats of this genus are the Common Bats of all countries, and may be easily known by their comparatively thick bodies, flat, broad heads, and obtuse muzzles (the thickne of which is increased in front by the rounded glandular elevations), short, broad, and triangular obtusely-pointed ears, obtuse and slightly incurved tragus, short legs, and by the presence in most species of a well-developed post-calcaneal lobule, which probably acts as a kind of adhesive disc in securing the animal's grasp when climbing over smooth surfaces.
