Craig (Capt. C. F.). The prophylaxis of malaria with special reference 

 to the military service.— War Dept., Office of the Surgeon-General, 

 Washington, B.C., Bull. no. 6, (Aug. 1914), 115 pp., 12 pis. 

 1 chart. [Received 23rd December 1914.] 



In this bulletin special stress is laid upon those measures that are 

 most applicable in the prophylaxis of malaria in the military service, 

 including service in the field, as well as in semi-permanent camps and 

 permanent posts. The earlier chapters treat of the malarial parasites, 

 malaria-conveying mosquitos, the prophylactic methods based upon 

 the destruction of mosquitos, the protection of man from their bites, 

 and the destruction of the malaria parasites (quinine prophylaxis). 

 A bibliography of 70 works down to 1913 concludes this bulletin, in 

 which all the Imowledge on the subject is gathered and presented in a 

 handy form.

 Mastoid Operation.— J^. A7ner. Med. Assoc., Chicago, III, Ixiii, 

 no. 6, 8th August 1914, pp. 479-480. 



On the third day after the radical mastoid operation had been 

 performed on a boy of 14, when the packing was removed, from 40 to 

 50 small maggots came away w^ith the gauze. The patient had spent 

 the summer on a farm in New Jersey. The larvae are believed to have 

 been those of the Texas screw-worm fly, Chrysomijia {Lucilia or 

 Comqjsomyia) macellaria, which often deposits its larvae in open wounds 

 or even in the nostrils of sleeping persons. In the present case the 

 patient probably became infected before the operation. 



•Chapin (R. M.). Arsenical cattle dips : Methods of preparation and 

 directions for use.— U.S. Dept Agric, Washington, D.C., Farmers' 

 BuU. no. 603, 14th August 1914, 16 pp., 1 fig. [Received Ist 

 March 1915.] 



As a handbook for users of arsenical cattle-dips, this bulletin 

 supplies general information, formulae, tables and practical hints on 

 the preparation and management of these dips. Changes in the com- 

 position and strength of the solutions have been dealt with in a previous 

 paper [see this Revieiv, Ser. B, ii, p. 145], but notes on the substances 

 employed in making up the solutions are given here. The boiled dip 

 is used in two strengths. The low-strength bath is commonly used 

 for ordinary tick-eradication, the cattle being dipped regularly every 

 two weeks for several months, if necessary. To make 500 U.S. 

 gallons (416 Impl.) of low-strength bath take : Washing soda, 24 lb. 

 (or monohydrated sodium carbonate, 10| lb.) ; white arsenic, 99 per 

 cent, pure, in fine powder, 8 lb. ; pine tar, 1 U.S. gallon (0*83 Impl.). 

 Put 25 U.S. gallons (20-82 Impl.) in a tank of about 45 gallons capacity, 

 heat to boiUng and add the washing soda. When this has dissolved 

 add the arsenic, then boil and stir for 15 minutes or longer, until the 

 white arsenic has entirely disappeared. If intended for immediate 

 use, cool to 140° F. (by the addition of cold water if desired), then pour 

 in the fine tar in a thin stream while constantly and vigorously stirring 

 the solution. Immediately empty the liquid into the dipping vat,
