doubt that control measures have already saved a considerable number 

 of lives ; although the population of the valley is increasing and the 

 disease itself is slowly spreading, fewer cases have occurred in recent 

 years. Complete coi trol will require some years, since the territory 

 involved is extensive and methods effective in one district are less 

 useful in another. Educational work among the people must be in 

 advance of actual control, and the life-history of the tick is such that 

 thoroughly effective measures must be pursued through a term of 

 years. In the discussion following the paper, Professor Cooley stated 

 that the tick was responsible for paralysis in sheep, and in view of the 

 recent work by Hadwen and Nuttall there should be no hesitation in 

 calling this a definite disease. [See also this Review, Ser. B, iii,

In Mozambique if cattle are neglected they become infested with 

 lice, and though death is rare, the animals are usually in poor condition. 

 The following species are noted as occurring : — On horses and mules : 

 Haematopinus asini {macrocephalus), Trichodectes filosus, Trichodectes 

 pubescens and T. parumpilosus. On cattle : HaemaLopinns eurysternus 

 and Linognalhus vituli {H. temdrostfis), Trichodectes scalaris and T. 

 biluberculatus. On sheep : Trichodectes sphaerocephalus. On goats : 

 Haemaiopinus stenopsis and Trichodectes climax. On pigs : Haemato- 

 pinus suis {urius). On dogs : Haematopinus piliferus and Trichodectes 

 latus. On cats : Trichodectes snbrostratus. The best known are those 

 which attack pigs and the usual mode of transmission is by actual 

 contact. Prevention is the best treatment and the adoption of all 

 possible means of securing cleanhness in the animals themselves and 

 their surroundings. The best general remedy is a decoction of tobacco 

 leaves, about 3 oz. well boiled in a quart of water and the liquor well 

 pre sed out of the leaves. For sheep, benzine 1 part, soft soap 6 parts, 

 water 20 parts ; mix and wash the affected parts. Hclileg's formula 

 is composed of arsenious acid and potash, of each 16 grams, water 

 and vinegar, of each 1| Utres ; mix and dissolve. Viborg's formula 

 is arsenious acid 32 grams, vinegar 2 litres, distilled water 1 litre, 

 but the author prefers the benzine formula. While on a journey to 

 the north, the author saw a herd of cattle with their necks perfectly 

 white from the number of eggs on the hair and many of them so 

 weak that they could hardly stand.

This report deals with the increased drainage work in Greenwich 

 and Madison during the year and the corresj)onding decrease in 

 malaria. In New Haven several old ditches have been cleaned and 

 new ones cut. Measures have been taken for the cleansing of West 

 River, which has hitherto furnished a breeding place for Cidex pipiens.
