122 HORSE AND CATTLE FLIES. 
‘‘They may be kept very much under by timely dipping, if not got rid 
of altogether.” * 
The different kinds of washes and dips, as also the time for appli- 
cation in reference to conditions of sheep, as well as circumstances of 
shearing time, repetition of dipping in order wholly to clear infestation, 
and all details, are so thoroughly understood by all interested in the 
subject, that it would be mere presumption on my part to say anything 
regarding treatment. But perhaps I may venture to draw attention 
to the book by Dr. Cooper Curtice, previously alluded to, published 
under the direction of the Secretary of Agriculture, U.S.A. It con- 
tains a great amount of serviceable information on internal and external 
parasites of the sheep most clearly given, embodying both the nature 
of the attacks in scientific detail, yet intelligibly to all, and likewise 
the treatment found to answer; each or almost every paper being 
accompanied by a full-sized good plate. It would be easily procurable, 
by order, from Messrs. William Wesley & Son (Agency of the United 
States Government Departments), 28, Essex Street, Strand, London, 
W.C. The title, put shortly, is as follows :— 
Curtice (C.), ‘ The Animal Parasites of Sheep.’ With Thirty-six 
partly Coloured Plates. Large 8vo, cloth. Washington, 1890. 12s. 
* ‘Farm Live Stock of Great Britain,’ by Robert Wallace, F.L.S., &c., Professor 
of Agriculture in the University of Edinburgh, p. 273.
