gitis (Borna disease), and of cases of congestion of the brain, subacute lepto- 

 meningitis, subacute encephalitis, purulent meningomyelitis, subdural abscess, 

 and chronic hydrocephalus. 



The investigations led to the conclusion that there is no regularity in the 

 blood findings in these cases. A bibliography of 37 titles is appended. 



Recent investigations of contagious pneumonia of horses and the sal- 

 varsan treatment of this disease, O. Schwartzkopf {A)iicr. Yet. Rev., 44 

 ilDlJf), No. 5, pp. 63.;-64i).— This Is a review of the subject. 



Streptococcic infections of the deep air passages of the horse, J. Eggink 

 (StreptokoJckauInfclctionen der tiefen Luftwege helm Pferde. Inaug. Diss., 

 Unw. Bern, 1912, pp. 33). — It is very certain that in inflammation of the deep 

 air passages of the horse the streptococci play an important etiological role.' 

 These streptococci possess a strong hemolytic action. In most cases they 

 possess the power to encapsulate on weak coagulated horse serum.

 Leipsic, 1912, pp. Jfl, pis. 2). — This paper includes reports of 18 cases personally 

 observed. 



Nematodes of the pharynx and esophagus of the chicken, J. Ciubea

The mechanical engineer's reference book, H. H. Suplee (Philadelphia, 

 1913, pp. 964; '■(^•- in Engin. Rcc, 69 (1914), No. 7, pp. 202, 203).— This book

 et Colon. Tunis, 17 (1913), No. 70, pp. 225-380, pis. 13, figs. 2.^).— This publica- 

 tion takes up in some detail the question of the conservation and utilization

 studies relative to projected work of this nature, which include rainfall, run- 

 off, and geological data and maps and charts, are as follows: Archaelogy and 

 Hydraulics in Tunis, by D. L. Carton (pp. 227-248) ; The Dam and Reservoir 

 of Hammam-Zriba near Zaghouan, by J. Coignet (pp. 249-265) ; The Legal 

 Management of Water in Tunis, by G. Barrion (pp. 267-275) ; How to Improve 

 the Management of Water, by L. Delaporte (pp. 277-283) ; Method Permitting 

 the More Abundant Use of Wells and Water Sources, by M. Malcor (pp. 285- 

 302) ; Rainfall of Tunis and Agricultural Hydraulics, by G. Ginestous (pp. 

 303-345) ; Agi-icultural Hydraulics in Tunis, by R. Gagey (pp. 347-355) ; Pros-
