Excerpt from Chemical Manipulation: Being Instructions to Students in Chemistry on the Methods of Performing Experiments of Demonstration or Research, With Accuracy and Success

Sidcrable, that of two persons having otherwise equal talents and information, the one who manipulates best will very soon be in advance of the other; for the one may obtain satisfactory conclusions from his experimental inquiries, while the other is left in doubt or led astray by his imper feet and incorrect results. This advantage may be illus trated by the use of the tinder syringe, a small instrument consisting of a cylinder about half an inch in diameter, and three or four inches in length, closed at one end and fitted with a piston, to the extremity of which a piece of amadou is fastened: by forcing the piston down and compressing the air suddenly, so much heat is evolved as to fire the tinder. Some persons cannot perform this simple experiment, what ever may be the strength or dexterity which they endeavour to bring into action; whilst others, 'with a very slight force. Will in every instance obtain the effect desired, and produce the required ignition. Were this a new experiment to the persons making it, the object being to prove whether air when highly compressed gives out much heat or not, - the first person would either come to a wrong conclusion, or, if be doubted the success of his experiment, would arrive at none at all, whilst the second would be enabled to form a correct and affirmative decision, and thus would have added an important fact to his previous knowledge.
