Acknowledges JH's comparison of Barclay Observatory results with those of other observatories. Sends more observations.

Sends CD information on two points which St George Mivart has asked him to provide, respecting the platysma myoides muscle. It is always in a state of violent contraction when a person is struggling for breath. In persons to whom chloroform is about to be administered, there is contraction but not so marked. No doubt contraction was strong before use of chloroform in operations.
