The intermediate fpecific gravities may be found by taking 
an arithmetical mean between the fpecific gravities by obferva- 
tion betwixt which that fought lies, and noting how much it 
exceeds or falls fhort of fuch arithmetical mean ; and then tak- 
ing alfo an arithmetical mean betwixt the mathematical fpecific 
6 gravities
