Latreille represents Humboldt as having seen Indians whose 

 bellies were covered by little tumours, which he believed to 

 result from the presence of bots in that region.* Similar 

 accounts are reported from La Condamine, Barriere, and 

 other travellers in America ; and a physician to the King of 

 Cayenne has sent to the French Academy of Sciences an 

 account of the frequent occurrence of bots in men and 

 women there. Further, D'Abreu is reported by Siebold, in 

 his article on parasites in Wagner's ' Handworterbuch/ as 

 describing the frequent occurrence of bots in a certain pro- 

 vince of Brazil.-}- 



" These numerous examples of the comparative frequency 

 of this affection in foreign countries, and especially in South 

 America, might be much extended by further quotation from 

 the article in the Transactions of the French Entomological 

 Society, already referred to, as well as from the paper of the 

 Rev. Mr Hope, in the Transactions of the Entomological 

 Society of London. If they convince us of the real frequency 

 of the disease in these countries, and if we observe the 

 remark of Gmelin on the smallness of the imago, we may be 

 left in hesitation as to the existence of a distinct species 

 in these quarters. 



" Although the disease is rare in Europe, yet cases of its 

 occurrence in almost every region of it, from Iceland to 

 Italy, are on record.J The case which came under my ob- 

 servation, and particulars of which were communicated to 

 the Medico-Chirurgical Society of Edinburgh in 1854, was,
