The kangaroo (Macro pus) lives in droves in the open grassy plains.
Those due to .Synchytrium, Protomyces, Cysto pus, many Ustilagineae, &c. These cases are not easily distinguished superficially froni the pustular outgrowth of actual mycelia and spores (stromata) of such Fungi as Nectria, Puccinia, &c. The cylindrical stem-swellings due to Calyptospora, Epichloe, &c., may also be mentioned here, and the tyro may easily confound with these the layers and cushions of eggs laid on similar organs by moths.
Heterophylly is rather common among aquatic plants, and is well seen in several aquatic species of Ranunculus, many species of Potamogelon, Sagittaria sagittifolia, Scir pus lacusiris, Castalia (Nymphaea) alba, Hippuris vulgaris, Callitriche spp., Sium latifolium.
Extensions of the flora occur southwards of the high mountains of tropical Africa; A denocaf pus, a characteristic Mediterranean genus, has been found on Kilimanjaro and 2000 m.
Trachycar pus and Rhapis are characteristic palms, and Cycadeae are represented by Cycas.
Amongst Conifers, Podocar pus is found throughout, Agathis is common to Australia, New Zealand and New Caledonia; Araucaria ~ ~he first and last.
If the invasion is due to a pus-producing micro-organism which settles in some local part of the body, the result is an abscess (fig.
By the aid of the new fibroblasts this fibrous tissue zone gradually encroaches on the pus area and replaces the phagocytic layer of cells as they proceed with the absorption of the pus mass (fig.
When complete removal of the pus mass has been accomplished by the process of absorption, the damaged area is replaced by the new fibrous tissue, which later becomes condensed and forms the cicatricial or scar tissue (fig.
- Healing abscess showing a wall of young cellular and vascular granulation tissue, which separates the pus area (top of Fig.) from the muscle fibres seen at lower part of Fig.
Pus being found, the abscess should be freely opened and drained.
To the commanderies of Gardeyne and Ascho: "Pus el es rey et papa et emperador !
Thus in Prussia the relations of the Roman Catholic community to the Protestant state are regulated by arrangement between the Prussian government and Rome; while in Bavaria the king, though a Catholic, is legally summus episco pus of the Evangelical Church.
Where there has been local mischief due to inflammation the dead leucocytes must be removed, and this is done either by their being converted into pus in one mass, and making their way through the tissues to the nearest surface, whether of skin or mucous membrane, from which it can be discharged, or they may undergo a process of fatty degeneration and absorption, leaving behind in some cases cheesy matter, in others hard connective tissue.
The number of exites is less constant, but, in A pus, two are present, the proximal branchial in function and the distal forming a stiffer plate which probably aids in swimming.
As regards their innervation an apparent exception is found in the case of A pus, where the nerves to the antennules arise, behind the brain, from the oesophageal commissures, but this is, no doubt, a secondary condition, and the nerve-fibres have been traced forwards to centres within the brain.
In some Phyllopoda (A pus) egg-sacs are formed by modification of certain of the thoracic feet.
The large number and the uniformity of the trunk somites and their appendages, and the structure of the nervous system and of the heart in A pus, are Annelidan characters which can hardly be without significance.
In many respects, however, the Phyllopoda, and especially A pus, have diverged considerably from the primitive Crustacean type.
It may be supposed to have approximated, in general form, to A pus, with an elongated body composed of numerous similar somites and terminating in a caudal furca; with the post-oral appendages all similar and all bearing gnathobasic processes; and with a carapace originating as a shell-fold from the maxillary somite.
