tissue or tbe source from which they are rterived. The iodin is, however, 

 independent of thyroid iodin in its quantitative I'elationships. 



" The thyroid gland of rabbits may at times be free from any appreciable 

 amount of iodin."

Serological examination in pulmonary tuberculosis with the optical 

 method, A. E. Lamp6 and J. Cnopf (Fermentforsch., 1 {1915), No. 3, pp. 269- 

 310). — From experimental data submitted the authors conclude that in those 

 cases which are not enemic or manifest no other clinical symptoms 

 there are in general no ferments in the system which can digest peptone 

 prepared either from normal or tuberculous lung tissue or from tuberculosis 

 bacilli. Individual cases, however, were found in which the serum contained 

 the specific ferments. 



In positive cases of pulmonary tuberculosis the ferments M'ere always found 

 which digested the substrates used. The intensity of the ferment action 

 seems to decrease as the disease progresses and finally disappears. The 

 authors believe that there is a "blood-ferment death" (Blutfermenttod) when 

 the ferments no longer exist in the blood, and that it is necessary to consider 

 this fact in defending the dialysis and optical methods against false criticism. 

 From the protocols conclusions are drawn as to the diagnostic and prognostic 

 value of the optical method in tuberculosis. 



The vaccination of cattle against tuberculosis. — III, The occasional per- 

 sistence of the human type of tubercle bacillus in cattle, T. Smith and M. 

 Fabyan {Jour. Med. Research, 32 {1915), No. 3, pp. 523-537).— It is indicated 

 that the injection of the human type of tubercle bacilli into calves may, in 

 rare cases, lead to the subsequent shedding of such bacilli in the milk. The 

 bacilli apparently lodge in the undeveloped udder and appear to be less readily 

 destroyed there than in other organs and tissues. The studies of a particular 

 case have shown that the human type of bacillus maintains its characteristics 

 even after remaining under the influence of bovine tissues for several years. 



The use of vaccines of the human type of bacillus for practical purposes is 

 not, therefore, to be generally advocated. " The situation as it lias been 

 developed by experimental work is, on the whole, against the use of such 

 vaccines, unless the milk from cows vaccinated as calves is either thoroughly 

 tested or else pasteurized before use."

A remedy for clover bloat, D. J. Healy and J. W. Nutter {KenUicky Sta. 

 Circ. 5 {1915), pp. 10-12). — The data here presented have been previously noted 

 from another source (E. S. R., 33, p. 388). 



The cause and occurrence of contagious abortion in cattle, E. C. Schkoeder 

 {Jour. Amer. Vet. Med. Assoc., ^8 {1915), No. 3, pp. 30^-310). — This paper, pre- 

 sented at the fourth annual meeting of the International Association of Dairy 

 and Milk Inspectors, October 28, 1915, at Washington, D. C. (E. S. R., 83, p. 

 701), includes a brief review of the present status of knowledge of this disease. 



Investigations into the cause of woitu nodules (Onchocerca gibsoni) in 

 cattle, at Darwin, Northern Territory, Australia, J. F. SIcEachran and 

 G. F. Hill {Melbourne: Govt. [1915], pp. S; abs. in Trop. Vet. Bui., 3 {1915), 

 No. 4, PP- 133, 134)- — The results of the authors' experiments are summarized as 

 follows : 



" Local cattle may become infected with worm nodules a few months after 

 birth, as well-developed nodules were found in calf (b). Cattle from Victoria, 

 where worm nodules are rarely, if ever, present, grazing in the ordinary manner 

 with infected cattle, may become infected with 0. gibsoni within six months, as
