The type of malaria most prevalent in the Jeypore Hill Tracts is 

 quartan, and the author thinks that the species of Anopheline present 

 is one of the factors concerned, the prevalence of quartan fever varying 

 synchronously with the rise and fall in prevalence of the stream- 

 breeding Anophehnes. The splendid physique of the inhabitants of 

 the Jeypore country, despite a spleen rate of 80 per cent, to 90 per cent. 

 in childhood, and a parasite rate of 80 per cent, is remarked upon. 

 The cUmate is deadly to Europeans, but the aborigines appear to be 

 immune and tolerant in a high degree of the presence of the malaria 

 parasite in the blood. Great difficulty was experienced in finding 

 Anophelines containing zygotes and sporozoites ; of 982 specimens 

 examined, only four, and these all ^. listoni, were found to be infected. 

 Attention is drawn to the relatively high percentage of A. listoni in 

 human habitations and their practical absence from cowsheds, etc. 



Cornwall (Major J. W.) & Patton (Capt. W. S.). Some Observa- 

 tions on the Salivary Secretion of the Commoner Blood-sucking 

 Insects and Ticks. — Ind. Jl. Med. Research, Calcutta, ii, no. 2, 

 October 1914, pp. 569-593, 2 charts. 

 Experiments show that the salivary secretion of Philaeniatomyia 

 crassirostris (ms%wts) contains a powerful anticoagulin ; the malesecre- 

 tion is weaker than that of the female, and less active in recently hatched 

 individuals of both sexes. The mensenteron contains a powerful 

 coagulin which is most active in flies from 20 to 44 hours after their 

 first feed of blood. The saUvary secretion of Philaematofnyior 

 does not produce any irritation when injected into the human skin. 

 Musca nebido, one of the house-flies, has neither an anticoagulin in 

 its salivary glands nor a coagulin in its mesenteron ; M. convexifrons 

 has no anticoagulin in its salivary glands, but a moderately powerful 

 coagulin in its mesenteron ; M. pattoni has a weak anticoagulin 

 in its salivary glands, and a powerful coagulin in its mid-gut. Stomoxys 

 calcitrans and another undetermined species, both lack an anticoagulin 

 in their salivary glands, but have a powerful coagulin in their mid guts. 

 The salivary glands of Tabanus albimedius contain a powerful anti- 

 coagulin, as also do those of Anopheles rossi and A.jamesi, the secretion 

 of the last two causing immediate agglutination of the red blood cor- 

 puscles. 



The secretion from the cardiac and ovoid salivary glands of Cimex 

 hemiptera (rotwidatus) does not appear to contain an anticoagulin, but 

 this may have been due to the escape of this fluid from the glands w^hile 

 dissecting them out. The mid-gut does not contain an anticoagulin or a 

 coaguhn. The ovoid salivary glands of Conorhinus rubrofasciatus 

 contain a powerful anticoagulin, the cardiac glands on the other 

 hand only a weak anticoagulin. No antibody was formed in the blood 

 of a rabbit on which large numbers of Conorhinus rubrofasciatus had 

 been fed for more than a year. The blood of a rabbit not so bitten 

 contains some substance which has a distinct inhibitory action on the 

 anticoaguUn.
