as a narcotic and irritant poison to both dogs and cats. Professor 

 Gofton recommends the following, used as a soap : Strong mercurial 

 soap, IJ oz. ; lard, 4 oz. ; soft soap to 1 lb. ; give two dressings at 

 intervals of one week, taking care to prevent the animal from licking 

 or biting itself ; long-haired dogs should be clipped.

The following mosquitos are recorded as carriers of malaria and other 

 diseases : — Anopheles crucians, Wied., widely distributed in North 

 America ; A. maculipennis, Meig., Europe, Canada, U.S.A. ; A. 

 (Myzomgia) rossi, Giles, India and the Phihppines, host for Filaria 

 bancroftii, but probably negative to malaria ; A. funesta, Giles, 

 Tropical Africa and the Philippines ; A. {C gcloleppteron) grabhamii, 

 Theo., Jamaica ; A. {Myzorhynehus) sinensis, Wied., Formosa, China 

 and the Philippines ; A. barbirostris, Van der Wulp. Selangor, 

 Upper Burma, and the Philippines ; reported to be experi- 

 mentally positive to malaria ; A. [Nyssorhynchus) fuliginosus, 

 Giles, India and the Philippines ; A. (Cellia) argyrotarsis, Kob., 

 West Indies, Brazil, Canal Zone, etc., also carries Filaria nocturna; 

 A. albimana, Wied., West Indies, Brazil, Canal Zone, India, etc. ; 

 A. tarsimaculata, Canal Zone, Central America, and southward ; 

 Stegomyia fasciata, ¥., of world-wide distribution in the Tropics, 

 carrying yellow fever ; Culex fatigans, W^ied., all over the world, 

 a host for Filaria nocturna, and concerned in the transmission 

 of dengue ; Mansonioides uniformis, Theo., South India, Perak, 

 Philippines, positive to Filaria nocturna in Africa ; and Mansonioides 

 africanus, Theo., Tropical Africa and the Philippines, perhaps also 

 positive to F. nocturna. 



The following species are referred to as being probably negative 

 to malaria .—A. punctipennis. Say, A. indefinita, Ludl., and probably 

 A. kochi, Don. A. pseudo punctipennis, Theo., and A.franciscanus, McC, 

 are most probably, but not certainly, carriers of malaria. Particulars 

 are also given of a number of doubtful species, including ludlowii, 

 Theo., and many others, the relations of which to malaria are unknown.

 the warble-fly.] — Deutsche Tierdrztl. Wochenschr., Hannover, xxii,

In a report of Dr. Glaser's address at the annual meeting held on 

 the 16th December, the following results of his investigations during 

 1913 are given. In an experiment with 10 young heifers of the same 

 age, five of which had been treated for warbles and the other five not, 

 it w^as found that in six months the weight of the treated animals 

 had increased, on an average, 34 lb. over that of the untreated ones. 

 At current prices, a difference of 15 to 16 shillings, would result in 

 favour of the treated animals. In the trial conducted in the district 

 of Neuhaus, 46,231 larvae were destroyed at a cost of about 9 shillings 

 per 1,000. An expert man removed 12,253 larvae in 83| working
