Is fruit the food for larvae or merely the substratum for yeast cells? c) Are products of fermentation
essential food requirements of larvae? d) Is yeast a complete food for larvae? e) Can …

METHOD Osmotic pressure was determined by the freezing-point depression method, described
by Jones (1897), using a Beckmann thermometer. The fluids of the crab were obtained …

The purpose of the paper is to attempt to relate and to show what connection there exists
between the potential impressed on a bare platinum electrode or on a dropping mercury …

The term" coupled redox potential" is defined. 2. The system lactic ion See PDF for Equation
pyruvic ion+ 2H++ 2e is shown to be reversible (when the enzyme is lactic acid …

A slowly dropping mercury electrode is shown to function as a reliable indicator electrode of
oxidation-reduction potentials which are sufficiently negative. The potentials are …

Method Materials.—The pyruvate used in these experiments was kindly given to one of us (JP
B.) by Dr. H. Bor-sook of Pasadena in the form of solid lithium pyruvate of great purity. All …

HE sudden increase in size of Crustacea when the hard exoskeleton is shed has been the
subject of much study. A review of most of the literature is given in the papers of Olmsted and …

The investigation of the effect of temperature upon insects discussed below was undertaken
at the suggestion of Professor CW Woodworth of the Entomological Department of the …

METHOD The method used was the oxidation of carbon monoxide to carbon dioxide by
iodine pentoxide, as described in the paper by Weisman (9), the liberated iodine being …

A method is described for the determination of the potential of any organic oxidation-reduction
system within the range of applicability of the dropping mercury electrode and from a …
