I regret to hear that one of the thermometers has been broken by an undue application of heat. No head should be applied greater than that of the hand. In future the Observers will be held answerable for instruments broken through want of care, or in judicious treatment. Until further notice omit description of clouds; at the same time your remarks might be a little extended.
No importance is allocated to the electrical observations at the regular hours, but it will be well to watch and record the indications of electroscope previous to and during thunderstorms.
I am sir
Your Obedient Servant
