tive action on the lungs and a remarkable action on the fever. It is said to be a 

 sterile isotonic solution of free and pure iodin in the colloidal state, which may 

 be purchased in ampoules of 1, 2, 5, or 10 cc. The injections may be made 

 hypodermically, intramuscularly, or intravenously, the last-named method being 

 ])referable. 



Poultry diseases and their treatment, B. F. Kaupp {Chicago, 1914, PP- 185, 

 figs. 56). — This is intended to fill a demand for a book on poultry diseases for 

 veterinary and poultry husbandry students and for veterinary practitioners. The 

 chapter headings are as follows: Anatomy, sanitation, external parasites, in- 

 ternol parasites, diseases of the digestive tract, diseases of the blood, constitu- 

 tional diseases, diseases of tlie liver, diseases of the ovary and oviduct, tumors, 

 diseases of the respiratory passages, disease of the legs and feet, diseases of the 

 brain, bacteria of the intestinal tract of chickens, the egg, isolation of non- 

 hiyers, malformations and fractures, wounds, and anesthesia. 



Investigations of the filterable virus of avian diphtheria and contagious 

 epithelioma of birds, S. von Ratz {Monatsh. Prakt. Tierheilk., 25 {1913), No. 

 1-2, pp. 41-46). — -The introduction of the virus from diphtheritic pseudomem- 

 branes of the throat into the scarified skin produced pathological changes 

 characteristic of epithelioma and, inversely, the introduction of particles of 

 epitheiiomatous tumors into the mucosa of the mouth and pharynx produced 

 diphtheritic lesions. In later experiments here reported, in which filtrates of 

 emulsified substances from a Nordtmeyer-Berkefeld filter were used, similar 

 lesults were obtained. 



The author concludes that these affections of fowls are only two forms of a 

 disease of which the causative agent is a filterable virus.

Preliminary report on ground water for irrigation in the vicinity of 

 "Wichita, Kansas, O. E. Meinzer {U. 8. Geol. Survey, Water-Supply Paper 

 345-A {1914), pp. 9). — This paper, the first of an annual volume to be entitled 

 Contributions to the Hydrology of the United States, gives an outline of the 

 geology of the Wichita region with especial reference to its water resources. 

 Types of wells and well casing methods are briefly discussed, and a table of 

 partial analyses of the ground waters in the vicinity of Wichita is given which 

 shows " that although the ground waters are generally somewhat hard and 

 otherwise mineralized they differ widely in the quantities of mineral matter 

 that they contain. ... A large proportion of the samples analyzed represent 

 waters that are satisfactory for irrigation use, but a few of the most highly 

 mineralized samples approach the danger line, especially in their content of 

 common salt. However, with the relatively humid conditions that prevail in 

 this region and the consequent dilution and leaching that will result from the 

 rain water, injury from the salt in even the more highly mineralized waters
