A brief account is given of the numerous insects attacking farm 

 animals in Quebec. The injury caused by them is described and 

 remedial and preventive measures are advocated.

In the peripheral blood of a native, who died of malaria in -Algeria, 

 the three forms of malaria, Plasmodium praecox, P. vivax and P. 

 malar iae, were found to be coexistent. Owing to the lack of data 

 concerning the patient's antecedents and the possibility of simulta- 

 neous or successive infections, no conclusions can be drawn as to the 

 confirmation or otherwise of the unicist theory respecting malaria 

 parasites.

 Parasites du Paludisme. — Bull. Soc. Path. Exot., Paris, xv, no. 2,

The author is of opinion that not only do three species or varieties 

 of Plasmodium exist, but that they form three groups containing 

 numerous varieties. Some of the many forms recorded as distinct by 

 other authors are enumerated. The results of immunity reactions 

 would seem to be in favour of the theory of a multiplicity of races. 

 Thus, natives of Senegal, though resistant to malaria in their own 

 country, succumb to the fever in Dahomey ; they may even become 

 infected in the interior of Senegal, though remaining immune along the 

 coast.

Flagellates have been isolated from the latex of Funtumia elastica 

 and Thevetia nereifolia in Florence, and should apparently be included 

 in the genus Herpetomonas, any differences being probably due to the 

 imusual medium.

A new flagellate, Crithidia oxycareni, has been isolated from a 

 Lygaeid bug, Oxycarenus lavaterae, on the Malvaceous shrub. Althaea 

 syriaca. Smears of the faeces of these insects contained large, round
