WARBLE FLY. 
to have the good results of stamping out warble attack whilst still in 
maggot-state clearly shown. The one point which as yet has not 
been observed is where the egg is laid, or rather how it is placed on or 
in the hide. This is not very important, but any observations bearing 
on prevention, or on points connected with this attack, will be grate¬ 
fully received. 
Those observers who may wish to study the minute scientific de¬ 
scription of the (Estrida will find excellent information in ‘ Monographic 
der (Estriden,’ von Friedrich Brauer ; descriptions, with serviceable 
life-histories, of the Hypoderma bovis are given in ‘Praktische Insekten 
kunde,’ von E. L. Taschenberg, part iv., pp. 84, 85 ; and the founda¬ 
tion of a large proportion of the information usually met with—that 
is sound, plain, and of practical use—is to be found in the ‘ Essay 
on Bots of Horses and other Animals,’ by Bracy Clark, F.L.S., pub¬ 
lished in 1815. But our present research is putting the matter on 
such a practical and demonstrable footing from what we can all see 
in our own country, that I venture to submit to those who refer to me 
relatively to study of the subject that observations from life, both of 
the attack and of successful treatment, are of far more value than any 
quotation from already published books.
