Analysis of Sour Milk. 



the female coats them with earth. In the other genera the 

 number probably varies to some extent. Geophilus is said to 

 lay its eggs in an earthen cell ; Scolopendra to bring forth living 

 young. 



These pests are frequently distributed with leaf mould, which 

 should, therefore, be examined before being used, and if found 

 to contain them should be mixed with lime. Their numbers in 

 the field may also be lessened by broad-casting lime over the 

 surface and working it into the soil. Soot and water, in the 

 proportion of a handful of soot to half a gallon of water, is found 

 to drive them away from the roots of garden plants for a time. 

 The)- may also be trapped in numbers by placing pieces of 

 mangolds scooped out just under the ground near the plants 

 they are attacking ; they swarm over the baits and may then be 

 collected and destroyed. 



Another certain way of killing them on small areas is by 

 injecting bisulphide of carbon into the soil. They may also be 

 trapped by soaking decaying cabbage leaves or decaying roots 

 in Paris green and placing them about in gardens ; the milli- 

 pedes feed upon them and thus get poisoned.* 



Analysis of Souk Milk. 



The fact that samples of milk referred to the Government 

 Laboratory under the provisions of the Sale of Food and Drugs 

 Acts are invariably sour when received, has occasionally given 

 rise to inquiries, by magistrates' clerks and others concerned 

 with the working of the Acts, as to the practicability of making 

 a satisfactory analysis of sour milk, with a view of substantiating 

 or disproving an allegation that the milk has been mixed with 

 water, or that fat has been abstracted from it.
