Several of the above works, while professing to deal with 

 human parasites only, cover more or less of the whole ground 

 of helminthology. Leuckart's work is invaluable in this 

 respect ; and in the matter of literary references of a profes- 

 sional kind Davaine's treatise is itself well nigh exhaustive. 

 In any ordinary volume it is not possible to give a complete 

 bibliography of parasitism. I make no pretension to do so 

 here ; nevertheless, the large number of modern memoirs that 

 I have received from the distinguished writers themselves, 

 enables me to render this part of my book very useful. As 

 second only in importance to the above-mentioned works may 

 be added the following whether minor treatises, memoirs, 

 monographs, comprehensive articles, or reports of a general or 

 special character, respectively. As such it will be seen that 

 some of them are sufficiently comprehensive, and their mere 

 enumeration will enable the beginner to realise something like 

 a fair estimate of the scope of helminthology. In the case of 

 my own works I have ventured to add references to reviews
