As an officer of engineers he presented to the National Assembly in 1790 a Memoire on the standardization of weights and measures.
In this standardization, one of the hallmarks of civilization, mathematical exactitude and specialized skill go hand in hand.
Standardization within the LMS locomotive fleet by 1934 rendered obsolete the larger non-standard boilers of the second batch of locomotive fleet by 1934 rendered obsolete the larger non-standard boilers of the second batch of locomotives.
To some extent it is there, even when standardization in form and decoration generally predominates.
In early inquiries a great point was made of the prevention of putrefaction, and work was done in the way of finding how much of an agent must be added to a given solution, in order that the bacteria accidentally present might not develop. But for various reasons this was an inexact method, and to-day an antiseptic is judged by its effects on pure cultures of definite pathogenic microbes, and on their vegetative and spore forms. Their standardization has been effected in many instances, and a water solution of carbolic acid of a certain fixed 'strength is now taken as the standard with which other antiseptics are compared.
