breed there. The only parts on which I ever saw them 

 myself were the inner angles of the eyes, on the tarsal con- 

 junctiva, and in the ears. The application of those ex- 

 ternal remedies which readily destroy the common species 

 of Pediculi, failed entirely in extirpating these ; a variety of 

 internal means were likewise used unavailingly, and the 

 insects were not admitted to be sensibly diminished in 

 number at the time of my quitting Devonshire ;" though 

 the patient's general health had been a good deal benefitted 

 by the treatment. In fact she considered that her feelings 

 were on the whole most comfortable when these ' small deer ' 

 were disposed to take an airing. A great similarity will 

 be observed in this case and that of Lady Penruddock, re- 

 corded by Mouffet, with the exception that her disease was 

 Acariasis, and of a more terrific nature and termination ; 

 while this was a pure case of Phthiriasis, and caused by 

 the genus Phthirius. Whereas many of the cases attributed 

 to this disease were said to be caused by Pediculi, some of 

 which are correctly reported ; while others are doubtless 

 caused by Acari, which an unentomological observer might 

 easily confound. To one or other of these maladies, con- 

 founded under the term Morbus pedicularis, however, we 

 find that the rich, the wise, the noble, and the mighty have 

 fallen victims. Exclusive of other names of less note are 

 those of Pheretima, as recorded by Herodotus, Antiochus 

 Epiphanes, the Dictator Sylla, the two Herods, the Em- 

 peror Maximian, and Philip the Second.
