Where necessary the aliquot was evaporated and taken up in other solvents. Rotenone was determined gravimetrically B by the method of Jones and Graham 16 ,and total extractives A by evaporation of an aliquot of the chloroform extract Colors obtained by the Goodhue modification IO of the Gross and Smith method I d were compared in a neutral wedge photometer using a filter with its optical center a t 0.
In general, this test is thought to be given principally by rotenone and deguelin in derris and cube. Cahn, Phipers, and Boam 4 state that pure inactive deguelin gives a color value about 80 per cent of that given by rotenone. Therefore, by subtracting from the color value for the samples under study C the value for rotenone B and multiplying this difference by 1. According to Cahn, Phipers, and Boam 4 , this value for ordinary derris roots such as Nos.
The values obtained in this study are roughly in agreement with this, when one considers that Cahn and his eo-workers calculated rotenone from the crude solvate, whereas in this work the slightly lower values for pure rotenone are used, thus making the differences greater in the present work. To avoid interference from toxicarol, the alkali-soluble material was removed prior to the oxidation. No attempt was made to separate the dehydrorotenone and the dehydrodeguelin as outlined in the original method.
The values obtained E and the differences between these and the rotenone content B , which should represent the deguelin content, are shown in F. The gravimetric values for the derris roots are on the average lower than those by the color method, while for the cube and timbo roots the two methods are in general agreement.
The dehydrogenation in the gravimetric procedure may not be entirely quantitative, and the crystallization probably involves a slight loss. This may account for a small part of the difference between the two methods. However, the comparatively large differences for some of the derris roots suggest the possible presence in these samples of a small amount of material giving the red color test but not forming a dehydro compound. The values for deguelin by either the colorimetric or the gravimetric method may thus be in error for this reason.
It was shown several years ago 16 that the values by the Gross and Smith color test give a better indication of toxicity of derris and cube samples to insects houseflies than does either the rotenone or the total extractives content. Similarly Tattersfield and Martin 26 have found the value for dehydro compounds a good measure of the insecticidal value to aphids of derris samples.
Thus, whether or not these two methods determine only rotenone and deguelin, they a t least are of definite value in giving an approximate indication of toxicity.
The color method is simpler and in the Goodhue modification is far more sensitive than the gravimetric pro- VOL. It is to be hoped that some such method as these, which give a closer approach to insecticidal eficacy than do rotenone or total extractive determinations, will eventually be adopted in the commercial handling of derris and cube roots.
The sulfuric acid-nitrite test G was made as described by Meyer I , and comparisons were made with a rotenone standard in a Duboscq type of colorimeter without a filter. Cahn, Phipers, and Boam 4 state that the test is given with equal intensity by rotenone, deguelin, toxicarol, and sumatrol, and by derivatives of these, and that the value for derris extracts is about 90 per cent by this method.
It has been learned in a private communication from Dr. Cahn that he used a modification of the Meyer test. For the derris samples in the present work the values averaged about 90 per cent of the extract, but the cube roots gave somewhat lower values.
The Rogers and Calamari test 22 was slightly modified in these analyses. The color in acetone solution was not proportional to the rotenone present, and after a short time solutions of different rotenone concentration developed t o about the same color. In chloroform solution the proportionality between color and concentration seemed to hold. Heat as well as light accelerated the color formation, but the latter was adopted. The solutions were exposed in glass cylinders to daylight at the laboratory window never to direct sunlight for 24 hours.
Perchloric acid was found t o effect a more rapid development of the color than the hydrogen peroxide used by Rogers and Calamari. The hue and intensity of the color varied with the amount of perchloric acid used as was the case with other oxidizing agents. At a rotenone concentrati,on of 0. Even in this form results obtained by the test were highly erratic, and duplicate standards run a t the same time varied as much as 10 per cent.
The reaction merits further study, however. Deguelin was found t o give a color about per cent of that given by rotenone, whereas toxicarol gave only about one half the color given by rotenone. Since the values obtained on the root samples H , particularly those for the cube and timbo roots, are markedly higher than the total extract values, it is apparent that some constituent in the roots gives a much greater color value than does rotenone or deguelin.
The ferric chloride test for toxicarol and sumatrol I was made as described by Cah,n, Phipers, and Boam 4, and comparisons were made in a Duboscq-type colorimeter. Solutions were compared in pairs, consisting of a standard and an unknown, each pair being prepared fresh. A sample of toxi. He is a lecturer in creative reading at the University of Canberra.

He was the man to whom my impoverished father sent me from my earliest years, to act as his companion-in-arms against you to come fight here. While reigning safely, he stood tall in committees of the kings — as did I — earning their respect and our power. But when Palamedes was struck by the envy of that two-face believe me, I know Ulysses, and sank down from the world above I drowned my days out, in broken spirits, in shadows, in grief at the destruction of my innocent friend, but raging inside.
And mad as I was I could not hold it in; I swore that if I ever returned to our Achaean homeland, at the first opportunity, and in the midst of our victory, I would avenge him; and so I targeted their hatred upon me. From that moment, I date the beginning of my fall; Ulysses now began to terrify me with accusations of the unspeakable. He started to spread his lying tongues about me in the crowd, laid traps for me, sowed teeth against me, plotted with skill relentlessly and then, with Calchas the priest in his pay — But why am I telling you this wretched and pointless tale?
Why stop time? But the land is mounds of snow, shapeless and deep in cold, it rises as you walk all around you. His horses from morning reaching for the far skies, the Sun never succeeds in scattering the paling shadows; his car rushes to bathe in the red mirror of ocean.
Night the shadows revives. Bridges of ice congeal, of a sudden, from flowing rivers. Whose waves then carry wheels bound with iron on their backs. Having once served ships, they now pave a way for open carts.
The cold causes bronze vessels to leap apart, clothing stiffens when put on, they cut off blocks of frozen wine with an axe. While pools, in their depths, turn solid ice, fierce icicles make caves of uncombed beards, and the snow all through the air, is all this time falling.

So you see both limbs, one virtual, one real, move perfectly now, as if the motorbicycle had never cut the other off. She became herself, unaware that she could never have children. Adoption had failed her and her husband. But her features being slightly more masculine were all the more feminine, her biology teacher explained.
The devastated seventeen-year-old girl still to menstruate, now finding out why, broke down and the teacher showed her, to calm her, the genes xy in a sample of her blood, and repeated that masculine features actually enhanced feminine beauty. Tall and striking, now forty-five divorced. Her husband never knew that his teen love was a man, not only on the inside, but all through till she told him. The marriage survived through trauma, and died.
The woman and her teacher were reunited after an ad-break by the producers, and she cried, in her body, she cried at her secret, to its first sharer, the human body, her teacher. Attend to this portion too of my poem, Maecenas.
I shall sing of vistas to amaze you in the world of little things, their great-minded leaders, their customs and callings, their nations and battles, all in order; my work treats of a slight theme, but the glory will be great if the adverse powers allow it, if Apollo hear my prayer. Do not allow sheep, or little head-butting goats to trample down the flowers, keep baby cows, wandering in the plains, from shaking the dew free, or wearing away the grasses as they grow.
Keep the painted lizards with their stiffening spines far from the rich houses, along with the bee-eaters and the other birds, Procne the swallow among them whose breasts bear the marks of her own bloody hands.
For they lay waste to all around. They fly off with bees in their mouths, as sweet snacks for their merciless young. Where am I to find you? And while Daedalus was placing the bones of his poor boy in the grave, a chattering partridge looked on from a muddy ditch, applauded with his wings, and in song testified to his joy. Only recently transformed, he was the sole bird of his race still, his fate an everlasting reproach to you, o inventor.
Partridge, a boy of twelve years, his mind open to learning. Already he had cut rows of teeth in sharp steel, taking for his model the backbone of a fish. Thus he discovered the saw.
He had bound with one knot two steel legs; one would stand fast while the other, at a constant distance, would draw in a circle. Daedalus, jealous of his nephew, threw him from the holy citadel of Athens. But the boy, whom Athena adored for his mind, was caught by the goddess and returned as a bird: Not quite.
For the partridge, despite his wings, does not trust himself to heights, nor lodge his nests on the tips of tall branches. Near the ground he flies, lays eggs in hedges and, ever a memory of his ancient fall, fears heights. He left me a camera, single lens reflex colour film inside, that I remembered, three years later to open and bring to light.
The next day returned twenty-four prints in a surreally damaged pink light stained as if sun set and I cried, when I saw none of him. You are my house.

Prima donna glares, dagger in hand, assumes the stage. Second act — the tenor grieves his mother — Third act — the daughter kills her husband — Ohime! The initial letter of a medieval page paints a scribe: A jar contains brazilwood, for which red-ink- bearing-trees the nation was named, far in the future when books were already the crops of paper unlike Folio h, in the British Library, which once had eyes and ate.
Once the skin of sheep or calf, also pig, squirrel and hare, even deer was stripped from the animal and washed in clear cold running water one day and night, and began to rot, the hair fell out and their skins were scraped to parchment on a beam, heads cut off, and then hides folded from A3 to B4, always rectangular, because so was its exemplar — shorn of legs — and we still today read books with rectangular pages.

The rumour ran like a madman through the close-shocked city, the ceilings of buildings rumbled with weeping, with groaning and the wails of women, the upper air echoed with grief.
It was as if all Carthage, or ancient Tyre, had been destroyed, the enemy was within and passionate flames twisted through the houses of men, the houses of the Gods.
