The subject-matter of the first of these papers is indicated by its 

 title. It is considered possible that dogs suffering from filariasis may 

 prove to be dangerous carriers as regards man. The diseases known 

 as Babesidiosis canis surinamensis and Filariasis canis surinamensis 

 are both due to varying developmental stadia derived from Macro- 

 filaria canis surinamensis. 



In the second paper, equine filariasis, which was unknown to science 

 a few years ago, is described from cases observed in Surinam.

A slight outbreak of malaria occurred during the summer of 1917 

 on the borders of Argonne in a district occupied by a camp of infantry 

 and engineers, the neighbourhood consisting of vast forests interspersed 

 with damp meadows intersected by streams. The nearest village, 

 which had been evacuated, was between 2 and 3 miles distant from the 

 area frequented by the troops. Many mosquitos occurred in the 

 district, of which Anophelines constituted 6 to 8 per cent., the larvae 

 of A. hifurcaius and A. maculipennis being found, not only in stagnant 

 waters, but also in the streams and rivers. 



A. hifurcaius was seldom m.et with in houses, but on the borders 

 of the woods, at twilight, it constituted 2 "8 per cent, of the mosquitos 

 in summer. A. maculipennis, on the contrary, appeared to be a 

 domestic species, seeking the cool dark corners of houses, stables, etc., 

 during the day, often at a distance of more than 2 miles from its 

 breeding-places, and representing 75 per cent, of the mosquitos present. 

 This same proportion occurred in uninhabited districts, however, 

 such as abandoned foresters' huts, showing that the presence of man 

 is not the attraction. In the evening, this species leaves the houses 

 and seeks the woods, where it attacks man. The Culicine, Ochlerotatus 

 {Theobaldinella) nemorosus, during the day lives in the woods, seeking 

 houses at night. In damp weather the percentage of A. maculipennis 

 found in houses is much smaller, being reduced to from 10 to 20 per 

 cent. Another species found, though rarely, was A. plumheus, Hal. 

 (nigripeSi Staeg.), with habits like those of A. bifurcatus. 



The cause of the outbreak of this malarial epidemic is uncertain, 

 malaria being unknown in the district before the War and no case 

 having occurred before 1917, in spite of the numerous and varied 

 contingents which occupied the district during the first four years of 

 the War, and the high percentage of Anophelines present during the 

 warm months. In the regiment in which the outbreak occurred there 

 were neither recognised malarial subjects nor recruits from Salonica.
