PATHOLOGY. 109 



lined secretions and decomposing excreta under a high tem- 

 perature and much attendant excitement, found suffering 

 from glanders, or farcy, or both. Mr. Fleming, in his ' Sanitary 

 Veterinary Police,' mentions, as a necessary accompaniment or 

 consequence of the collection of large numbers of horses, and 

 the wasting and depressing influences operating on these when 

 engaged in active campaigning during our more recent Euro- 

 pean wars, the sudden and extensive distribution of glanders 

 amongst the cavalry horses composing the armies engaged in 

 these operations. It is there particularly noted that ' the mag- 

 nificent German cavalry that invaded France took the field 

 after every care had been exercised that no glandered horses 

 should be in the ranks ; and yet at the end of the campaign 

 every regiment, it is reported, was more or less infected, the 

 necessities and hardships of war havmg as usual engendered 

 it.' I believe, however, that since this was written my learned 

 friend has seen cause to change his views respecting the gene- 

 sis of glanders. Very similar is the experience recorded by 

 those connected with the British cavalry during our invasion 

 of the Crimea. 



Many of those who have the professional charge of large 

 studs of horses in civil life tell the same story. 



It has also, it is stated, been found that locating horses in 

 newly built, imperfectly dried, and untempered stables has 

 been found to act prejudicially, b}^ developing glanders. 



AU these causes, essentially exhausting and depressing, 

 favour the development of this or any other disease cha- 

 racterized by vitiated and depraved blood, and impaired, de- 

 fective, or perverted nutrition, resulting in serious structural 

 alterations and tissue-changes. 



They do this — (1) By the production of noxious miasm, 

 deleterious agents resulting from the changes of surrounding 

 organic compounds, and the entrance of these into the animal 

 body. (2) By increasing the natural waste and tissue-change, 

 and by further and pernicious alteration of these changed, as 

 also of the imbibed materials. (3) By preventing the natural 

 elimination, through arrest of activities by which naturally the 

 system rids itself, not merely of the normally used-up materials, 

 but of those which may have been unnaturally formed there, or 

 introduced from without.
