 last for months and even years, and they then more or less affect 

 the health of the subjects according to the organs that were most

In certain cases, in domestic animals such as dogs, and more 

 rarely in man, after recovery from tbe bite of a viper, total or 

 partial loss of sight, smell, or hearing, has been observed. Such 

 results, however, are fortunately exceptional.
