The Colloidal State in Its Medical and Physiological Aspects.

This monograph is an attempt to give a short, but accurate, account of the properties of colloids, so far as these have bearing on the phenomena that occur in living beings. The author is himself an active and successful investigator in this field. There are brief chapters on the nature of the colloidal state, interfacial phenomena, precipitation, osmotic pressure, viscosity, surface tension, inhibition, physiologic action, and a concluding chapter on proteins and hemoglobin. The significance and probable action of inorganic drugs administered in organic or colloid combinations is briefly discussed in the chapter on physiologic action. The volume is admirable in clearness of diction and in judgment on the many unsettled questions in this field, but there is little or no reference to the literature. The book is a useful aid to biologists and physicians who try to keep abreast of the important advances in colloid chemistry in their relation
