CHAPTER XVI 



LETTERS TO MR. GRIMSHAW, MR. WISE, AND MR. 

 TEGETMEIER 



The Red-bearded Dot fly Deer and Ox Warble flies Caddis flies Black 

 Currant mites Crusade against the House Sparrow Miss Ormerod's 

 pamphlet and Mr. Tegetmeier's book on the Sparrow. 



THE grouping of the letters to three correspondents, so 

 differently interested in Entomology and other branches of 

 Biology, was more a matter of dates than of any scientific 

 relationship in the subject matter, (i) Mr. Grimshaw, the 

 well-known authority on Scottish Diptera, was also the first 

 investigator to show that the so-called " frosted " condition 

 of heather was caused by a beetle larva ; (2) Mr. Wise was 

 one of Miss Ormerod's most interested correspondents in 

 questions relating to fruit-growing and market-gardening ; 

 and (3) Mr. Tegetmeier was her colleague through the 

 trying days of the Sparrow controversy, in which Miss 

 Ormerod was subjected to bitter personal attacks by her 

 opponents. He was always ready to lend assistance in 

 relation to questions dealing with birds and the four-footed 

 animals.

DEAR SIR, I write at once to thank you very much for 

 the copy of your paper on the Cephenoiiiyia rufibarbis (Red- 

 bearded botfly), in the " Annals of S. Nat. Hist." Will this 

 be the attack figured (in its effect on the deer) in Dr. 

 Brauer's spirited frontispiece to his " CEstridae " ? * 



[In the last few days I have had sent a nice specimen of
