NOTES ON PARASITES. 453 



again from a purely human standpoint — of dangerous forms. 

 These facts are to some extent explained by the recent 

 settlement of the country and the uncontaminated condition 

 of the fields. This state of affairs, coupled with the exist- 

 ence of large slaughter-houses where, as the meat-packers 

 eloquently express it, " The only part of the hog which goes 

 to waste is the squeal," is to a great extent responsible for 

 the absence of those parasites which afflict the human species 

 whether through his person or his pocket. 



Of the Nematodes enumerated in the table, Ascaris 

 my s tax is rarely found in man, its accidental introduction 

 into the system being due probably to the fondling of dogs 

 or cats. Uncinaria trigonocephala produces a profound 

 anaemia in dogs, especially in the sporting species. It 

 occurs also in cats and gives rise to the disease known in 

 Italy as tifo dei gatti, but does not attack man. The other 

 species mentioned in the list are comparatively unimportant. 



To the student of parasites one of the most important 

 features of the present year is the appearance of the Ar- 

 chives de Parasitologic, under the able editorship of Prof. 

 Raphael Blanchard, of the Faculty of Medicine, Paris. 

 However much the multiplication of new journals is to be 

 deplored, there was undoubtedly room for a periodical 

 devoted exclusively to the study of parasites, whether they 

 affect man or other animals, and judging from the first three 

 numbers, the Archives are worthy to fill the vacant place. 



Two features about the journal are new. One is the 

 appearance of Spanish in addition to the four languages, 

 French, English, German and Italian, to which polyglot 

 zoological publications have hitherto been restricted. There 

 is much useful work on Helminthology and Bacteriology 

 being done especially in the Spanish-speaking Republics of 

 South America — the opportunities are great — which only 

 finds expression in the Spanish tongue ; the cost of learning 

 enough of the language to follow a scientific treatise is small, 

 so that on all grounds we applaud the courage of Prof. 

 Blanchard in adding Spanish to the list of languages in 

 which articles for the Archives may appear.
