CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 159 



not recognized as identical with the common types, and bow, in conse- 

 quence, its true characters, its prevalence, and, above all, its conta- 

 gions property were ignored, until anatomo-pathological observations 

 showed the identity of the lesions in ditt'erent organs, and biological ex- 

 periments established the true nature of the disease germ. 



He thinks Moses refers to phthisis in the word dlirre — (leanness) Lev. 

 xxii, 22 — and Columella, as ])hthisis (De re Rustica); the same idea is 

 embraced in most of its common designations — as pining, consumption- 

 decline. iSchicinden, Schicindsucht^ \AitYnsis, nlceratio?ipulmonaire, Lungen 

 versehiciirvnfj, hmgensiicht, lurKjenfUule sulliciently illustrate. 



Another form has been named and classified, on account of sexual 

 aberrations, nymphomania, satyriasis, Stiersucht, f/eilesucht, Monatsreiterei 

 (German), nin/omania, furore nterino (Italian), Brumniel (Swiss), bull- 

 ing (English). 



Another form has been named, from the more or less firm excrescences 

 which appear on the serous membranes and skin — rerlsneht, Mirse- 

 siuht, MeerUnsif/keit, Ziipjigkeit, Kranichtheit, Rindsliammen, Trauben- 

 Icranlheit, i)earl disease, knots, kernels, grapes, angleberries, clyers. 



The supi)osed syphilitic cliaracter of the disease produced the fol- 

 lowing names: Franzosenkranlcheit, Francoiisoicitost pri Kraicaeh, Lust- 

 seuche, Unreinigleif, reneric et morbus gallirus boum. 



The implication of the glands and the sarcomatous and fibrous charac- 

 ter of the growth has given rise to still other names : Driisenkranklieit, 

 malattia glandulare, sarlcomdyskrasie, cahexia bourn sarcomatosa, sar- 

 comatosis infectiosa, sarco-tuberculosis, tnbervulosis fibroinatosa, riiids- 

 tuberculose, &c. Again, as it appears in the pig in the form of scrofula, 

 it has been called scrofula tubercle. 



Ko wonder that the identity of all those forms of the disease was slow 

 to be recognized, and that pathological anatomy and inoculative ex[)eri- 

 ments had to be invoked to determine it. The name to be preferred is 

 the generic one tuberculosis (or tuberculosis panzootica contagiosa), and 

 yet this must not be held to imi)ly that tht^ nodosity (tubercle) is a con- 

 stant and pathognomonic feature of the disease. 



The manifestations of the disease are entered on fully, showing that 

 after the i)reliminary slight fever (marked symptoms often snl)side and 

 of the local lesions are confined to certain non-vital organs) there may 

 be comparatively little sign of illness for months or years. The (low 

 of milk may be abundant, and though variable yet of no fixeil quality, 

 and the animal may breed, work, or even fatten without suspicion. As 

 the diseased i)rocesses extend over the system febrile symptoms reap- 

 pear and tend to assume a remittent character, the temperature becom- 

 ing abnormally low in the morning and high toward night, and at the 

 same time wasting advances more or less rapidly. I^nlargment of the 

 cervical lymi)hatic glands, irregular appetite, tympanies, colics, (Con- 

 stipations, and diarrheas, and indications of lesions of the respiratory 

 organs, are especially common. In certain cases there may be muscu-
