Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1919 edition. Excerpt: ...with chloral hydrate, the same or a tendency to a higher reactivity with chromic acid, and a lower reactivity with potassium hydroxide. The types of curves of the rhizomatous and tuberous irids, respectively, differ chiefly in the relative lowness of the rhizomatous curve in the reactions with pyrogallic acid, nitric acid, hydrochloric acid, potassium hydroxide, potassium iodide, sodium hydroxide, sodium sulphide, calcium nitrate, uranium nitrate, copper nitrate, cupric chloride, and mercuric chloride, and the highness in those with chloral hydrate and sodium salicylate. Probably among the irids will be found some species or hybrid that will, as in case of the crinums, bridge the two series. Owing to the almost invariable closeness of the three curves in each set, opportunity is rarely afforded for a satisfactory study of the relationships of the hybrid to one or the other or both parents. It will be seen by the following summary, the figures of which are to be taken as having only tentative values, that the different hybrids vary in their parental relationships, especially in their intermediate, highest, and lowest records. The following is a summary of the reaction-intensities of the hybrids as regards sameness, intermediateness, excess, and deficit in relation to the parents: 114 HISTOLOGIC PROPERTIES AND REACTIONS. 34. Comparisons Of The Starches Of Gladiolus Cardinalis, G. Tristis, And G. Colvillei. In histologic characteristics, polariscopic figures, reactions with selenite, qualitative reactions with iodine, and qualitative reactions with chemical reagents the parents and the hybrid exhibit properties in common in varying degrees of development and also individualities which collectively are in each case distinctive, although the...show more
