P. papatasii, Scop., and P. sergenti, Parr. The author was bitten 

 by P. sergenti, but no data were obtained showing that P. minutus 

 or P. fallax habitually attack man. 



Both males and engorged females were taken of a new species, 

 Ctdicoides langeroni, Kieff. 



Cimex lectularius and Argas persicus occur, but no trace of 

 Ornithodoriis could be found.

 est-elle hereditaire chez le Pou ? — Arch. Inst. Pasteur Afr. Nord,

It has been concluded that the infection of typhus is hereditary 

 in the louse [R.A.E., B, x, 48] as a result of a positive inoculation 

 with the product of ground louse eggs collected on a case of typhus. 

 The author disagrees with this view, as he did when it was originally 

 briefly enunciated \R.A.E., B, ii, 90] and, discussing the detailed 

 statement, concludes that not only is hereditary transmission not 

 proved, but that it is not probable.

The laxwdLeoiOestrus ovisiniesi the frontal sinuses of sheep. Lyperosia 

 irritans [Haematohia serrata) attacks cattle, generally at the base of the 

 horns, but exceptionally it also attacks sheep. As the larvae live in 

 cattle dung, where they develop in two or three weeks, and as the 

 insect has seven or eight generations in a year, cattle sheds should be 

 kept clean and disinfected with creolin.

 27th January 1922.] 



Texas fever has been indigenous in Porto Rico for a very long period, 

 and the native cattle have acquired a high degree of immunity, but 

 foreign cattle, which are imported in large numbers, suffer greatly from 

 the disease. Treatment of the animals has not given satisfactor}^ 

 results, and it is realised that the only reliable method is the extermina- 

 tion of ticks that transmit the disease ; the value of arsenical dips 

 in this connection is discussed.

Experiments here described show that the trypanosome of camels 

 in Turkestan is identical with that of camels in the Ural. It is probable 

 that the Astrachan form is also the same.
