ond, the anaphylactic reaction following the injection of mallein; 
third, auto-inoculation; fourth, the inoculation of the guinea pig, 
producing orchitis with chanchroid lesion; fifth, the agglutination 
method (Widal reaction), which means, briefly, clumping or ag¬ 
glutination caused by a chemic substance in the germ called ag¬ 
glutinin with another chemic substance in the serum called ag¬ 
glutinogen; sixth, the discovery of precipitinogen formation in 
the blood, stimulated by precipitin contained in the product of the 
germ ; seventh, /the Wasserman reaction, or fixation of the com¬ 
plement. Of these several methods unfolded it is to be hoped 
that a practical and reliable method has been found for the certain 
diagnosis of glanders early in the disease and before the clinical 
symptoms have appeared. 
Statements have been made in newspapers, two or three mag¬ 
azines, and recently in Prof. L. H. Pammels’ Bulletin on Poison¬ 
ous and Medical Plants of Missouri assuming that there might 
be a possible relation between pelagra of the horse and the same 
disease in man. Having been a close observer of diseases of the 
horse for several years and doubting the reality of such a disease 
in the horse, effort has been made to trace the authority for this 
assumption, but without success. To assume that poisoning of 
the horse by pathogenic fungi or the toxins of any organism as¬ 
sociated with food simulates pelagra in the human is going farther 
than the writer is willing to go- at this time. 
Dr. B. F. Kaupp, of the Colorado State College, in his inves¬ 
tigation of poultry diseases, has determined the presence of two 
forms of the so-called white diarrhoea of chickens in Colorado, 
the bacillary white diarrhoea caused by Bacterium pullorum and 
the coccidian white diarrhoea due to Coccidium tenellum . Botn 
of these organisms have been isolated and both types of the dis¬ 
ease proven to exist in the Middle West. Dr. Kaupp reports that 
ordinary diarrhoea of chicks is controlled by sulphocarbolates 
compound and that white diarrhoea is successfully combatted by 
keeping the following mixture in their drinking pans from the 
day they are hatched : Sulphocarbolates compound, 1/2,000, and 
bichloride of mercury, 1/10,000. 
Paraplegia in pigs, lambs and rabbits, with 100 per cent, mor¬ 
tality, and in some respects simulating infantile paralysis of the 
human, suggests the possibility of a common or closely related 
etiologic factor. This condition has become so common in the 
Middle West and has an economic importance and scientific in¬ 
terest that warrants a careful investigation.
