“…This effect occurs for both chloride and sulfate mixtures, and, in accordance with the early results of Linder and Picton [3] on arsenic trisulfide sol, it becomes more pronounced as the differences between coagulation values of the individual electrolytes become greater. Thus, more than ten times the coagulation value of thorium chloride is necessary to induce coagulation when it co-exists with lithium chloride.…”

In an effort to interpret the phenomena which occur when viscose solution is extruded into the spinning bath, as in the viscose rayon process, the stability of cellulose xanthate sol in the presence of electrolytes has been studied. Coagulation values for various salts and mixtures of salts on cellulose xanthate are reported. From these values a classification of ions according to their coagulating power and mechanism of coagulation has been suggested. In similar fashion, the behavior of salt mixtures on cellulose xanthate sol has been classified as additive, sensitizing, or antagonistic in accordance with colloid-chemical theory. The rate of coagulation by different ions and the influence of the degree of sulfidity and the degree of polymerization of the cellulose xanthate on the coagulation values are discussed. These data can be correlated with changes which take place in the course of fiber formation during viscose rayon spinning.

“…Schulze (1882), Linder and Picton (1895), and Hardy (1900) showed that the coagulative power of a simple electrolyte depends principally on the valency of the ion carrying a charge opposite in sign to that on the colloidal particle, and increasing as the valency of this ion increases. For brevity this ion will be called the coagulating ion.…”

“…These two words were very kindly suggested by Prof. D. S. Robertson in place of the two German words "Nebenion" and "Gegenion" respectively, and since there exist no similar English words in current use, it is felt permissible to introduce these two new ones. Linder and Picton (1895) and Hardy (1900) showed that, for the systems they were studying, coagulation set in for a given coagulating ion but for different homoid ions when the conductivity of the solution reached a definite value independent of the homoid ion used. In general, it appears that, provided the homoid ion is not adsorbed by the colloidal particles, its influence on the concentration of the coagulating ion required to coagulate a given sol is mainly through its influence on the activity of the coagulating ion.…”

In this paper the general theory of the coagulation of dilute clay suspensions is discussed. The more important of the points considered are summarised below.1. Two separate mechanisms causing collisions between suspended particles are considered, namely their Brownian motion and the mass motion of one group of particles relative to another group. Following Wiegner, these two types of collision are called perikinetic and orthokinetic collisions respectively. The rate of coagulation of a suspension is then shown to depend on the rate of collisions between particles and on the probability of adhesion between them when they collide. If this probability is unity, that is if every collision between two particles results in their adhesion, the suspension is undergoing rapid coagulation. There is excellent agreement between theory and experiment for this type of coagulation whenever the mathematical equations involved can be solved. But if the probability of adhesion is less than unity, the suspension is undergoing slow coagulation, and there is as yet no theory capable of giving the rate of coagulation of such a system.

“…Moreover, if an acid is really present it is very insoluble as an aqueous extract of peat is practically neutral to litmus: and this is generally true of most "acid" soils. These views were based on the work of Linder and Picton (42) who showed that when As 2 S 3 is precipitated from colloidal solution by BaCl 2 a small amount of barium is carried down with it and a corresponding amount of HC1 is set free. If Ca-, Sr-, or K-chloride is used the same amount of HC1 is left behind showing that equivalent amounts of the base are absorbed in each case.…”

Soilfertility is often spoken of as though it were an absolute property of the soil; in reality it is a particular relationship subsisting betweensoil conditionson the one hand andcrop growthon the other. The conditions conducive to soil fertility are the resultant of two main groups of factors, theintrinsicproperties of the soil which are dependent on its chemical, physical and biological nature, and thoseextrinsicproperties impressed on the soil by topographical and climatic factors*. These two groups cannot be sharply distinguished from each other, nor can any hard and fast line be drawn between the various factors comprised in them, because few are at present susceptible of exact measurement. In other words, that particular group of conditions that make up the fertility of a soil is an equilibrium brought about by the interaction of numerous factors some of which however can be varied by the agriculturist by manurial and cultivation operations.
