408 BOARD OF AGRICULTURE. 



The first question that presented itself was, " "What will produce 

 a scar or cicatrix on the septum of a horse's nose, other than acci- 

 dents, purpura haBmorrhagica and glanders?" Dr. Bryden said 

 they were frequently the result of horse ail, or the feeding of cut 

 feed might cause them, while Drs. Lyman and Harrison did not 

 mention any other cause. Of the horses quarantined at this stable 

 Dr. Bryden saw two or three he would order off the street, while 

 Dr. Lyman said he would not condemn to death any of the quar- 

 antined horses without close observation for at least one year, 

 and he farther stated it was with that understanding he was 

 induced to review the work of the Commissioners. 



The next day the consultation was continued at the River Street 

 stable with about the same result, excepting that the veterina- 

 rians employed by the railroad acknowledged that they never 

 heard of or saw pin-7ioIe ulceration in connection with glanders. 

 Duprey, who has well described this species of glanders, charac- 

 terizes these "little ulcerations" as the result of the degeneration 

 of miliary tubercles, and represents them truly as having " thin 

 edges unevenly excavated, like pin holes, with this difference, 

 however : that the hole made by the pin would be deep and 

 pointed, whereas these ulcerations are shallow and have thin 

 edges." 



On the 17th of October the Board met the directors of the road 

 at then" office in Cambridge. Mr. Cummings gave an abstract of 

 Dr. Lyman's letter, containing conclusions he had arrived at by 

 the examination of the quarantined horses. He found different 

 shaped scars, — long, T-shaped, V-shaped and star-shaped, the 

 latter very suggestive of glanders, the others not so. The classi- 

 fication of the shape of scars as indicative of glanders is self- 

 assuvied and loitlioat precedent. 



Dr. Lyman stated that the officials did not deny the existence 

 of glanders in their stables. Dr. Lyman further stated that he 

 would require three lesions — gland, ulcer and discharge — to 

 satisfy him that a horse was diseased with glanders. He also 

 said that the chancre could not exist without swollen glands, and 

 in chronic glanders the sub-maxillary glands must show an abnor- 

 mal condition. 



Bouley says : " In fact, in some horses which were at work, and 

 which had neither glandage nor discliarge, glander pustules were 

 found in the nostrils. Generally few in number and isolated, 

 these pustules had not given rise to any notable irritation of the 

 raucous membrane supporting them, nor to increased secretion, no 

 abnormal amount of discharge issuing from the nostrils. There 

 was no apparent derangement of health or condition. Though
