251 SEAT AND NATURE OF GLANDERS. 



imagined the difFerence between strangles and glanders to consist 

 in one breaking ouiwardlie, the other inioardlie*. 



De Grey, or De la Grey, 1740, adopted Solleysell's notion 

 of glanders proceeding from neglected cold, distinguishing the dis- 

 ease " by the inflamed kernels or knots which may be felt under 

 the chaul of the horse." He, however, continued in the old errror, 

 of fancying that " the thinne rheume ascendeth up to the head 

 and settleth neere to the brain, and so venteth itself at the nose :" 

 the cold gradually getting worse and ending in glanderst. 



SOLLEYSELL, 1669, a French writer of this period, of excellent 

 repute, still considered glanders as related to catarrh, though he 

 did not suffer himself to be misled by the difFerence of colour the 

 nasal discharges assumed. Neither did he think — as those before 

 him had imagined — that the discharges proceeded from the brain, 

 but from the lungs, liver, and spleen. He thought glanders was 

 ** caused and fermented by an ulcer in the lungs;" which, increas- 

 ing, consumed those organs, and at length killed the horsej. 



Lafosse, in 1749, presented to the (French) Royal Academy 

 of Sciences " A MEMOIR OF THE GLANDERS IN Horses, relating 

 to the Seat of that Disease § ;" wherein, after exposing the errors 

 of those who had written before him, in supposing the viscera — the 

 lungs, heart, liver, spleen, kidneys, &c. — to be the seat of the dis- 

 ease, he informs the Academy that he had found the frontal and 

 maxillary sinuses filled with matter, and " the pituitary mem- 

 brane inflamed; and, consequently, much augmented in thick- 

 ness," and " affected with sanious ulcers : which, in some cases, 

 had corroded through the substance of it to the very bones. That, 

 when horses discharged matter from both nostrils, both sides of the 

 membrane were affected; and that when they only ran at one nos- 

 tril, that side only of the membrane was found distempered."
