land surrounding the shipyards, and the consequent interruption 

 of work. The matter became so serious that the Consulting Entomo- 

 logist of the State Board of Health was detailed to deal with it. 

 Drainage operations on the marsh were undertaken, with oiling of 

 the pools where ditching and draining was impossible. The complete 

 abatement of the mosquito nuisance was secured in the vicinity of 

 the shipyards by these measures. The restaurants that have sprung 

 up in the vicinity to meet the requirements of largely increased bands 

 of shipbuilders have also been inspected ; these were found to be in a 

 very insanitary condition and have been greatly improved, all places 

 where food is exposed being now screened from flies.

Among the diseases of sheep dealt with in this paper is that caused 

 by the sheep bot-fly [Oestrus ^ovis] [see this Review, Ser. B, vi, p. 93]. 

 The infestation very seldom does any serious harm to the animals. 

 To prevent the adult flies from attacking sheep it is suggested that 

 battens smeared ^ith tar should be placed about two inches apart 

 over a trough of food or over the lick. The tar becomes smeared 

 on the nostrils of the sheep and acts as a repellent to the fly.

The Cattle Tick in Australia. — Commonwealth of Australia Advisory 

 Council of Science & Industry, Melbourne, Bull. no. 1, 1917, 30 pp.,

Boopliilus australis (cattle tick) may affect the health of cattle in 

 two distinct ways, namely by conveying tick fever and by the 

 irritation, etc., caused by its presence. . This fact of the tick being 

 capable of giving rise to sickness per se by gross infestation, has not 

 always been recognised, and early records of the jDCSt refer almost 

 exclusively to tick fever. The particular form of piroplasmosis known 

 as tick fever in Australia is due to Piroplasma [Babesia) bigeminum, 

 which is also the cause of Texas fever in the United States of America 

 and similar diseases in Europe, Asia, South America and South Africa.
