“…In contrast to final shell size, shell growth rate in this study increased with increasing temperature over the entire temperature range. The Q 10 value for this rate increase (1-6) is comparable to Q 10 values observed for growth of some other sarcodines (Pace & Belda, 1944;Laybourn-Parry, Baldock & Kingsmill-Robinson, 1980). We do not know why chamber formation rate continued to increase from 25 to 28 °C while average final shell size decreased and the frequency of second spheres increased (presumably indicating suboptimal conditions) for this same temperature shift.…”

Orbulina universa d'Orbigny is a spinose planktonic foraminifer which occurs throughout surface waters of the tropical, subtropical and transition zones of the world ocean (Bé & Tolderlund, 1971). This species is unique among planktonic Foraminifera in that its life cycle is composed of two growth stages. The juvenile stage is a trochospiral form which is enclosed within a terminal spherical chamber in the adult stage. O. universa is relatively omnivorous, and consumes a variety of prey that range in size and quality from phytoplankton to copepods (Bé et al. 1977; Anderson et al. 1979; Spindler et al. 1984). In addition, each individual harbors several thousand zooxanthellae which presumably are an additional source of nutrition for the foraminifer (Be et al. 1977; Hemleben & Spindler, 1983; Spero & Parker, 1985).

“…Before each experiment the organisms were washed thoroughly in a buffered solution in which they were left during the experiment. This solution is one similar to that used by Pace and Belda (1944) for Peloinv.ra, with slight modifications/" and was used for these tests chiefly because of the several advantages it has over the proteose-peptone solution. It is much simpler to work with since there is no 1 Aided by a grant from the Penruse Fund of the American Philosphical Society.…”

Unicellular organisms make excellent material for the study of various cellular phenomena. Tctrah\nncna t/clcii, a colorless holotrichous ciliate, is an exceptionally desirable organism for such physiological studies, mainly because it is readily grown in rather simple, sterile organic media. This organism contains cytochromes c, b, a, and possibly a._, and its oxygen consumption is inhibited by cyanide and carbon monoxide (Baker and Baumberger, 1941). It grows well at ordinary oxygen tensions, but is most prolific in pure "oxygen (Pace and Ireland, 1945). It soon dies in oxygen tensions below 10 mm. Hg partial pressure.Many investigations have been carried out with Tetrahymena as the experimental organism. There is, however, much to be desired in respect to our knowledge concerning respiratory metabolism ; knowledge that may lead to a better understanding of the respiratory mechanisms of cells in general. Since very little is known concerning oxygen consumption, carbon dioxide elimination, and respiratory quotient in Tetrahymena, the following investigations were made.

“…The organism used in these investigations, Pelomyxa carolinensis Wilson (also referred to as Chaos chaos. Chaos carolinensis and Amoeba carolinensis), was 97 grown in a solution developed by Pace and Belda (1944). The medium was composed of the following: K,HPO 4 -80 mg. ; KH 2 PO 4 --80 mg. ; CaCl, --100 mg. ; Mg, (PO 4 ) 2 -4H 2 O -2 mg.; and redistilled water to 1000 ml.…”

“…The Barcroft-Warburg respirometer was used to ascertain oxygen consumption. This was done by means of the "direct method" as described by Pace and Belda (1944). Tests were made on pelomyxae in solutions without alcohol, and in solutions containing 0.005 M and 0.01 M alcohol.…”

Among the first of comparatively few studies made on the effect of alcohol on unicellular organisms were those of Calkins and Lieb (1902) and Woodruff (1908). These workers used Paramecium and in general concluded that ethyl alcohol, in "moderate" concentration, acts as a stimulus in sustaining the vitality of these cells.On the contrary, Matheny (1910) and Estabrook (1910) found no evidence that alcohol acts as a periodic or continued stimulus. In minute doses, 2% or less, it apparently has no effect on Paramecium while in doses of 3% or greater, it kills them. Daniel (1909) working with another genus, Stentor, found that ethyl alcohol causes an increase in growth rate. He also states that comparatively weak solutions of alcohol (1% or less) are ineffective, while a 4% solution causes
