cheese-mites also, as well as 

 those from dried fruits, 

 raisins, &c., may produce a 

 transitory irritation upon the 

 skin, but no disease (e. g., 

 pustules, and other exanthe- 

 mata; Raspail). Nyander's 

 intestinal itch (scabies in- 

 testinorum epidemicd) and his 

 Acarus dysenteric certainly 

 belong to mites which already 

 occurred in the night-chairs, 

 &c., and which we meet with 

 in old vessels and in decaying 

 places (Martiny), or to the mites of raisins or dried fruits, such as 

 Reinhardt, of Bautzen, found in the vomited matter from a woman 

 who suffered from cancer of the stomach and ulcus perforans 

 ventriculi.
