ACTINOMYCOSIS OF THE LIPS. 



In the rich river bottom lands of northern Germany and Russia 

 where actinomyces abound actinomycosis is common in the 

 form of papillae of greater or lesser size on the lips and nose of 

 horse and ox. The abrasion of these parts b\' thorns, thistles, 

 stubble, dry fibrous fodders and other irritants, appears to pro- 

 duce a raw surface for the colonization of the germ, which is not 

 slow to avail of the opportunity. The resulting lesions take the 

 appearance of warty looking elevations, more or less indurated, 

 which on .section show the sulphur-yellow actinomyces tufts of 

 club shaped cells converging to a central mycelial mass. 



Treatment is simple as the disease is at first essentially local, 

 and is easily checked by the local application of iodine. The 

 wartlike elevations may be shaved off with a razor or cut oflf with 

 sharp scissors and the surface painted once or twice daily with 

 tincture of iodine. If there is suspicion of distant or deepseated 

 actinomycosis the internal treatment with potassium iodide will be 

 in order. 



TROMBIDIOSIS OF THE NOSE AND LIPS. HARVEST 



ITCH. 



In different parts of Europe and America, and especially in the 

 warmer regions, or in sheltered gardens, shrubberies, and past- 

 ures, different species of the trombidium abound, and the young 

 hexapod larvae attack man and beast, burrowing under the cuticle 

 and giving rise to extreme itching and persistent and irritating 

 rubbing of the affected part. These parasites belong to the 

 family of acari or mites, so that the condition they produce is one 

 of acariasis or mange, only the offender is not a compulsor}' para- 

 site, but appears to survive in certain soils and in the vegetation 

 independently of animal hosts. Their parasitism is therefore 

 accidental and non-es.sential to their survival. 



The tronibidian parasite usually found in Europe is the Trom- 

 bidium Holosericeum or silky trombidium, so small (in its larval
