tirst, to prepare a galvaiiized-iroii receptacle of convenient size, with au 

 apartment for ice and another for the insects, so that the temperature 

 i'ouldconstautlyandcertainlybekeptatalowpoint/ This we conceived to 

 be a much better phin than to rely upon the reliijij;erators of vessels and 

 trains. We also urged that a duplicate lot be kept at a normal tem- 

 perature, active and constantly at work and breeding throughout the 

 jom^ney. This method retpiired that they should be carried in sucli a 

 way that they could be examined from day to day, and tliat a good su])- 

 ply of food in the shape of living Icerya should be taken if possible on 

 living plants in pots. We advised Mr. Louw to call upon Mr. Alexander 

 Craw, the chief quarantine officer, on his way to Los Angeles, and we 

 anticipate the most profitable results from his mission to this country. 

 In addition to Mr. Louw's effort Mr. Koebele has, in accordance with 

 instructions, carried very large numbers of Yedalia in the ej^^^x and 

 larva state from New Zealand to Australia, with the intention of ship- 

 ping them from there to Cape Town. He found on his arrival at Syd- 

 ney that no steamer would sail within a reasonable time, but he is wait- 

 ing an opportunity to start his sending over. While he is in Australia 

 we have every hope that the shii^ment can be made. 



A Monograph of the Insects and other Animals injuring Tobacco.*— Prof. 

 Ad. TargioniTozzetti has Just published an elaborate work on the subject 

 of the animals and insects of growing tobacco and of the dried product, 

 under the auspices of the Royal Excise Department, and with the 

 assistance of the Government agencies for the manufacture and culti- 

 vation of tobacco. He has gone over the entire ground of tobacco ene- 

 mies in all countries, devoting 270 of his 300 pages of text to the sub- 

 ject of insects proper, six pages to vertebrates, seven to snails, ten to 

 arachnids, and one to earthworms. In all, 144 species of insects are 

 treated, nearly all of them being delineated by means of very fair wood 

 cuts, and their work being shown by several full-page plates. The in- 

 sects are considered in their systematic order, and the matter of reme- 

 dies is discussed under each insect. Where several species of a given 

 group occur upon tobacco, synoptical tables to enable their separation 

 are published. The work is prefaced by a bibliography and concludes 

 with a very full index. The tobacco insect, of which there is the most com- 

 plaint in this country, viz, the Cigarette Beetle {Lasioderma serncorne), 

 is treated at some length. The author concludes that on account of the 

 special abundance of this insect in tobacco brought from this country to 

 Europe its origin may be accorded to America. As a remedy for this 

 pest he recommends a thorough use of chloroform, bisulphide of carbon, 

 and hydrocyanic acid gas in disinfecting warehouses and manufactories, 

 and he also advises, where possible, the submersion of the tobacco in
