The last two species may be successfully controlled by applying spirit 

 extract of sabadilla, mercury ointment, both the grey and white, 

 solution of corrosive sublimate of a strength of 1 : 250 to 1 : 100, amyl 

 and ethyl alcohol, benzine, choroform, carbon tetrachloride, methane, 

 birch-tar, Hquid of Malinin, etc. The control of P. humanus is very 

 difficult owing to its ability to withstand some of the above remedies 

 and to its life-history, which makes the application of some of them 

 impracticable. To destroy the parasites in the clothing of troops, 

 only gases must be used, such as the vapour of chloroform, carbon 

 tetrachloride or methane and SO 3. The latter may be applied in the 

 following way : a mixture of tartaric acid and sodium sulphite shghtly 

 moistened with water is placed in small linen bags underneath the 

 shirt ; the temperature of the body produces a reaction which con- 

 tinues for two days, giving off a large amount of SO 2 (100 grms of 

 sodium sulphite give 22-4 litres of SOJ which spreads underneath the 

 shirt and kills all the parasites while not affecting the skin in any way 

 or causing discomfort to the wearer. The author has proved this by 

 experiments on himself. The cost, per man, of 15-20 grms. of the 

 mixture is only a few farthings.

soldiers of the active armies, their importance and remedies 



against them], pp. 68-70. 



Attention is drawn to the necessity of combating Pedicnlus humanus 



{vestimenti) in order to protect the army and the civil population from 



outbreaks of spotted and recurrent fever. Frequent bathing and 



washing of the underclothing is the best preventive remedy against 



ectoparasites. Soaking linen in birch tar, liquid of Malinin, kerosene, 



creosote, ether-oils, etc., can also be used as preventive remedies, while, 



in cases when the clothes and linen are already infested with parasites, 



they should be subjected to treatment with S0„, kerosene, liquid of 



Malinin, birch tar, acetic acid, or the Helios apparatus. Shaving and 



washing the head, followed by smearing with xylol, kerosene, acetic 



acid, liquid of Malinin and mercury ointment are recommended 



against Pediculus capitis.

The author illustrates the dangerous consequences, both for the army 

 and the civil population, which may result from the part played by 

 insects in carrying various diseases. He refers more or less fully to 

 Mtisca domestica, which is responsible for carrying typhoid, cholera 

 and other diseases, to Stojnoxys calcitrans, the bites of which may lead 

 to infection with siberian-sores (anthrax ?) and probably also with 

 erysipelas and epidemic cerebro-spinal meningitis, and to Anopheles, in 

 connection with malaria, which may threaten the army on the 

 Caucasian-Turkish front. Prophylactic quinine for the whole army, 

 after March, is urged, and measures should also be taken against 

 Pediculus humanus, which carries typhus and recurrent fever, the 

 latter disease, according to some authors, being also carried by Cimex
