Strona 267 - Body cylindro-fusiform. Superior division presenting four sides of a hexahedron, subacute. Nuclear body of inferior division transparent, globular or elliptical, containing several coarse granules. Length from 1/66 to Yt, lines; head 1/400 in.
Strona 116 - Reproduction asexually by conidia produced either solitary or in chains Conidiophorae Suborder Sporangiophorae I. Sporangia generally only of one kind, spherical or pyriform, with a membrane that dissolves or fractures easily. Sporangioles with persistent membranes occur very rarely and in such cases are disposed without order along the principal sporangiophore. The septum separating the sporangiophore from the sporangium arches in the interior of the latter to form a columella. Zygospores naked...
Strona 207 - Known bondholders, mortgagees, and other security holders, holding 1 per cent or more of total amount of bonds, mortgages or other securities: (If there are none, so state.) None.
Strona 282 - processes of the epimerite disappearing shortly after the animal frees itself from the intestinal wall of the host, but the conical part persists in the sporont stage, giving a symmetrical margin to the front of the protomerite.
Strona 274 - ... the body ; expanded individual with a protomerite equal to or longer than the deutomerite, the anterior fourth of the protomerite hemispherical to subglobose, below which is an elevated flange-like portion, remaining...
Strona 59 - Characterized, with a few exceptions, by a dingy-white, membranous peridium, which elongates into a tubular form and tends to rupture along the sides; by large peridial cells usually conspicuously sculptured on the inner and side walls (see Fig. 4, a) ; by aeciospores with colored walls and evident germ-pores4; and by teliospores with hyaline pedicels of considerable length, the outer portions of which swell in moisture and become gelatinized to form a jelly-like matrix in which the spores appear...
Strona 159 - Ill., received his education at the University of Michigan, and began the practice of medicine at St. Louis in 1895. At the time of his death he was Professor of General Medicine in the Medical Department of St. Louis University, was president of the consulting staff of the City Hospital, medical director of the St. Louis Society for the Relief and Prevention of Tuberculosis, a member of the St. Louis Medical Society, Missouri State Medical Association, American Medical Association, Medico-psychological...
Strona 122 - ... without order along the principal sporangiophore. The septum separating the sporangiophore from the sporangium arches in the interior of the latter to form a columella. Zygospores naked or surrounded by appendages Mucoraceae II. Sporangia as with the Mucoraceae but of two kinds: the one multispored, with membrane that dissolves, leaving only a naked columella ; the other (sporangioles) few-spored, with persistent membrane, often without columella, caducous. The sporangioles are disposed at the...
Strona 234 - bridge" for the mildews on B. racemosus and B. commutatus. Salmon tested .this in one case by infecting B. hordeaceus with conidia from B. racemosus. The conidia produced on the former were then used to infect B. commutatus. Similarly Steiner regards Alchemilla pastoralis as a "bridge" for Spharotheca humuli to pass from A.
Strona 267 - ... gregarines remarkable for the small size of the head and hence the species may be named Gregarina microcephala. The body is clavate; the head like a watch crystal with a little ball at the summit. Length 0.35 mm. by ol wide; head 0.012 long by 0.04 wide.
