SOME OBSERVATIONS ON CYSTOSEIRA FOENICULACEA (L.) GREV. EMEND. SAUVAGEAU

Cytological studies on physodes in the vegetative cells of Cystoseira stricta Sauvageau (Phaeophyta, Fucales).

Physodes have been recognized in meristodermic and promeristematic cells by correlated light- and electron-microscope investigations using different fixation procedures. They are vesicles which contain an osmiophilic material of phenolic nature. Their content changes in appearence according to the fixative used. Osmiophilic deposits are often associated with coiled and disturbed lamellar format...

To Emend or not to Emend : On Determining the Integrity of Some Ancient Chinese Texts

Some new observations on L forms of bacteria.

The first, part of the paper contains observations on the development of the L forms of Proteus on the surface of liquid media and the properties of the cultures so obtained. This type of culture was described by Tulasne (1950). These cultures provide L forms in masses which can be separated easily from the media. Our interest was attracted especially by the observation that these cultures diff...

Some Observations on Dirac Measure-Preserving Transformations and their Results

Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...

Some Observations on "Influenza"

Sir,?I am not attempting in this letter to give any elaborate or comprehensive history of the disease, nor do I consider it necessary to tire my readers by a repetition of its etiology, symptoms or pathological manifestations so ably and voluminously narrated in any good text-book of medicine. I shall only give, in brief, a few features of this disease that came to my notice in the recent epide...
