To disinfect a barge of 12,000 cubic feet capacity, half an ounce of 

 potassium cyanide per 100 cubic feet proved sufficient. Rats and 

 fleas placed in different situations in the hold were nearly all killed 

 after four hour's exposure to the fumes, though many survived one 

 hour's exposure. In another experiment, an epizootic was started 

 in a store-room, where a number of fleas were placed together with 

 bundles of old clothing and gunny bags half full of rice. The clothes 

 and gunny bags were later removed to flea-free store-rooms and it 

 was found that, whereas infection occurred in the former, no plague 

 was found among the rats where the gunnies had been placed.

[On the destruction of external parasites in the army.] « HOBOe 

 BpeMfl.»— [iVot'oe Vre7mja], Pefrograd, 21st December 1914, p. 5. 

 The author advocates the use of the liquid of Dr. Malinin as a 

 protection against lice in the army in the field. This hquid has been 

 successfully used in many parts of Caucasia for the destruction of 

 mosquitos in barracks and camps during the campaign against malaria. 

 According to Dr. Girgoriev, the liquid was sprayed at night over the 

 walls, ceihngs, etc., of the rooms where the soldiers were sleeping, and 

 their beds, their hands and arms as far as the elbows and legs as far 

 as the knees, i.e., all parts of the body which are, or may become un- 

 covered during sleep, were also sprayed. The result was a rapid death 

 of the mosquitos present in the rooms and no new mosquitos entered 

 during the night. All flies, bugs, fleas, Simuliidae and other human 

 parasites were also killed. Some dogs, suffering from a parasitic skin 

 disease, were also quickly cured by the application of this hquid. 

 An experiment was also carried out on 40 pigeons suffering from lice, 

 20 of which were used as controls, while 20 were subjected to treatment 

 with this Hquid ; of the former 8 died and only 1 among the latter. 

 The liquid does not in any way affect the health of men, has no effect 

 on the skin, but irritates the mucous membranes, so that the soldiers 

 had to shut their eyes, when it was applied to their faces. It has a 

 greenish yellow colour and a shght smell of birch tar ; cotton and 

 woollen materials retain this smell for 2-3 days, when kept in the open ; 

 while hnen, w^hen worn underneath other clothing, retains it for a still 

 longer time. It destroys rubber, so that it must be sprayed through 

 metal tubes. In July 1910, the author had an opportunity of testing 

 the liquid, while passing a night in the house of a forester, situated on 

 one of the branches of the Volga ; before going to bed he sprayed 

 the room and his bed with the liquid and neither was he annoyed by 

 mosquitos, nor did he see any in the room during that night. He is 

 convinced that no parasites can live in linen sprayed with this hquid. 



The following is the recipe for the preparation of the liquid of 

 Dr. Malinin, as given on pp. 16-17 of Dr. A. X. Grigoriev's work,
