any reaction whatever. The trial was repeated with the same 

 ticks on ten head of cattle, one of which was, as before, regarded 

 as susceptible, and the other nine had been released from 

 the Kamiti testing* area as immune ; the nine escaped, the other 

 died. It seems therefore at least to be clear that an animal 

 immune to East Coast fever is also immune to the S. African form 

 and that therefore the diseases are identical.

 Amer. (Columbus), v, pt. 4, pp. 421-430, 2 pi. 3 figs. 



The author describes the distinctive characters of Musca 

 domestica, L. (the House Fly), and Fannia (Hovialomyia) 

 canicularis, L. (the lesser House Fly) and of StomoA-ijs cal- 

 citrans, L. (the Stable Fly), discussing the internal anatomy of 

 the last-named in detail. In one plate the three flies, their larvae 

 and pupae are figured side by side.

Culex pipiens, C. aurifer, C, canadensis, C. sylvestris, C. 

 salinarius, Anopheles viaculijjennis and Wyeoviyia smith ii appear 

 normally only at night and are to a certain extent attracted by 

 light of low intensity. Near the close of the season impregnated 

 females of C. pipiens seek dark hibernating quarters in spite of 

 outside warmth. Aedes crucians is a daylight mosquito, while 

 A. punctipennis is attracted only by light of low intensity. 

 C. sollicitans does not regard the light or its absence when seeking 

 food. C. perturhans is not attracted by light, but C. cantator is 

 attracted. Most of the salt-marsh forms seek the light, e.r/., 

 C. sollicitans, C. cantator and C. taeniorhynchus ; but ('. sal- 

 inarius does not. Those species which do not fear the light are 

 the most active biters, although the light exposes them to the 

 attacks of their natural enemies.

 Ticks and Parasites on Cattle, and a Portable Bath for Foot-and- 

 Mouth Disease. — Agric. Jl. of India, vii, part 4, Oct. 1912, 

 pp. 382-386. 



The portable spray consists of an ordinary garden spraying hose 

 for use with a bucket, with the usual iron stirrup attachment to 

 enable the operator to use both hands. The rose sprayer is flattened, 

 liaving 10-12 large holes and with a concave perforated surface so 

 that the spray jets are concentrated Avhen thrown on the body 

 surface of the animal. Spraying is effected from the rear of the 

 animal the fluid being thus forced against the fall of the hair 

 and coming into direct contact with the skin. Cooper's Arsenical 

 Dip is the fluid used. The animals are made to stand on a zinc 

 lined tray so contrived that the waste dip is returned to a bucket 

 sunk in the ground. The tray is made in two parts for con- 

 venience of transport.
