166 THE ENTOMOLOGIST. 



ascertain whether any entomologist, who has used the ordinary 

 white crystalline form of naphthaline as a preservative against 

 mites, has noticed that any ill effects have resulted. I may add 

 that it has been used in my cabinets without any evil results, as 

 far as I can judge. — J. Jenner Weir. 



[We shall have some further remarks to make on this subject 

 in an early number of the ' Entomologist.' So far as our expe- 

 rience goes, after long trial, naphthaline appears by far the best 

 preventive against mites, and even mould, in collections, not 

 only of Lepidoptera, but also any prepared Natural-History 

 specimens, being highly fatal to life of any kind. — Ed.]

' Matahele Land, and the Victoria Falls.' Edited by C. G. Gates, 

 M.A. London : C. Kegan Paul & Co. 1881. Coloured 

 Plates and Maps. 



The work under notice has been apparently published as a 

 monument to one dead, by a surviving brother. The gist of the 

 work consists of a series of letters and memoranda written in 

 uncivilized Africa, by the late Mr. Frank Gates, F.R.G.S. These 

 have been edited by Mr. C. G. Gates with great care and evidently 

 as a labour of love. The work is profusely illustrated, not only 

 with woodcuts, but by chromo -lithographic facsimiles of water- 

 colour drawings taken by the traveller. These latter are very 

 striking, being full of colour, one — that of the Victoria Falls — 

 especially so. Added to these, in the Appendix are the plates 

 (nine of which are coloured), devoted to the natural history 

 portion of the work ; four of these concern the readers of the 

 ' Entomologist,' as they illustrate the more remarkable insects 

 found in the collection made by Mr. Gates. There are also four 

 elaborate maps for the reader's guidance and reference. 



The editor devotes the first thirty pages to a memoir, which 

 unfortunately but varies the too oft-told story of a young man who 

 leaving home in robust health, on his voyage of scientific and 

 geographical discovery succumbs to fever caused by the worry, 

 fatigue, and privation of African travel. This memoir is rendered 

 more sad by the clever cartoon, drawn by Mr. Charles Whymper, 

 of Frank Gates' favourite pointer dog standing by the graveside 

 of his master. This dog left the camp some eighty miles from
