Distilled and salt water compared 3 1 5 



Jan. 2 M. Same experiment repeated with the same water, which had been 

 left in the tubes all night. 



20 12 



1-4 plainly greater. 



1-9 seemingly less. 



2-1 plainly less. 



Therefore salt in 2999 conducts 22 times better than distilled water. 



The same experiment repeated, only the water in the tubes was changed 

 for fresh by pouring out the old and putting in fresh by small funnel, without 

 taking out the wires.

plainly greater, 

 plainly less. 



Therefore salt in 2999 conducts 72 times better than distilled water. 



The same experiment repeated, only the distilled water changed for that 

 used in the preceding year. 



4 considerably greater, 



i-i plainly less. -8 supposed equal. 



Therefore salt in 2999 conducts 47 times better than distilled water. 



Jan. 3. Experiment repeated with the same water left in. 



8 plainly greater. 



1-2 plainly less. 



Therefore salt in 2999 conducts 38 times better than the distilled water. 

 The distilled water changed for the new distilled water. 



28 plainly greater. 



6 plainly less. 



Therefore salt in 2999 conducts 86 times better than distilled water*. 



Salt in 2999 compared with salt in 150,000 in same tubes. 



1-2 43-5 sensib. greater. Electrom. = 4j. 

 1-7 sensib. less. 



Therefore salt in 2999 conducts 26 times better than salt in 150,000. 



The experiment repeated with the same waters, only the wires in tube 12 

 brought nearer. 



3 12-5 sensib. greater. Electrom. = ij. 

 45 sensib. less.
