man, and the disease of man so potent as to be transmissible to 

 the bird. Every precaution therefore should be taken to prevent 

 infection passing from one to the other. 



FOLIvICULAR CONJUNCTIVITIS. 



Common in dogs. Violent congestion with enlargement of lymph fol- 

 licles, or beneath the nictitans, dark red, like millet seed, also over sclera 

 and lids. Enlarged lymph follicles with excess of lymphoid cells. Often 

 chronic. Entropion. Infection. Treatment : astringent and antiseptic 

 lotions : lunar caustic : cocaine and crushing of follicles : pure air : excision 

 of nictitans. 



Frohner has drawn attention to the frequency of this affection 

 in the dog, which according to him attacks 40 per cent, of the 

 race. It is especially liable to begin on the inner surface of the 

 membrana nictitans, and though it may be at first somewhat 

 hidden by the severe congestion, yet when that subsides in part, 

 the swollen follicles can be seen as dark red elevations, the 

 size of a millet seed, when the nictitans has been everted. It 

 may extend over the sclerotic and palpebrse. Microscopically 

 these swellings are found to be enlarged lymph follicles, with 

 an excess of lymphoid cells. 



The disease tends to assume a chronic course and may cause 

 entropion and other troublesome lesions. The diagnosis depends 

 on the recognition of the swollen follicles, and especially in the 

 depth of the conjunctival sac. 



It is presumably infective yet all Frohner's inoculation gave 

 negative results. 



Treatment. In the earlier stages the common astringent and anti- 

 septic lotions may be used. Sublimate, or boric acid lotions are 

 especially valuable for their antiseptic properties. Should these 

 fail, the eyelid and nictitans may be inverted and the individual 

 follicles touched with a fine pencil of lunar caustic, the resulting 

 smarting being lessened by application of cold water. In case 

 they should still prove obstinate, the conjunctiva may be co- 

 cainized and the follicles individually crushed with ciliary forceps. 

 Pure out door air is a prime essential in the treatment. 



In extreme cases Frohner counsels the excision of the mem- 

 brana nictitans.
