This booklet is exclusive for its accomplished presentation of protease functionality within the belly, colon, pancreas and liver less than either physiological stipulations and significant ailments manifesting in those 4 organs. the person chapters were written by way of leaders within the box who define in nice aspect the position of proteases within the pathogenesis, analysis and therapy of sickness.
Das Elektronenmikroskop hat der submikroskopischen Morphologie zu einem ungeahnten Aufschwung verholfen. Die dank der Anwendung dieses Instrumentes laufend erscheinenden Arbeiten sind so zahlreich, dass es un moglich geworden ist, die . gesamte "Submikroskopische Morphologie des Protoplasmas und seiner Derivate" in einem handlichen Buch darzustellen, wie dies fruher geschah, bevor das Ubermikroskop zur Verfugung stand (Borntraeger, Berlin 1938).

My field observations have also indicated changes of shape in response t o environmental factors. The dwarf opuntia growing shallowly in a fastflowing inter-island channel of Enewetak Atoll in the Marshall Islands is a good example. ECOLOQY AND TAXONOMY OF Halimeda 37 FIQ. 16. Some of the variability which may occur in segment size and shape shown for H . gigrcs. Portions of the typical segments, which are reniform to discoidal and very large (Fig. 39), appear in the bottom of the picture, particularly the right-hand corner.
25. FIG. 12. Hudimerln (Corclllina,) incaassnta. These illustrations with analysis, by Ellis ( 1 7 6 7 ) , provide the type description of the species incrassata. Ellis’ work also represents the earliest known microscopical study of the genus. The habit (No. 20) illustrates the caulescent effect obtained when bmal segments remain unbranched. I n older plants a number of basal segments may become consolidated into a relatively massive struct,ure. ) ECOLOGY AND TAXONOMY OF Halirneda 21 be the earliest comparatively detailed examination of internal structure in Halimeda.
The pores associated with this pattern of filaments generally show up well if good longitudinal sections are made. The pores are lined up in adjacent filaments, and all the filaments appear to be involved in the fusion. Diagnosis for such material is straightforward. Occasionally, however, particularly in material of simulans, the pores may be small and relatively inconspicuous (Hillis, 1959). And in some specimens the connections between some of the filaments may be delicate and easily broken, giving the impression that the nodal structure is that of two or three large groups.
