32 Harley Street - JH did not mean to imply that the observer using WW's tide paper in the Admiralty Manual [John Herschel ed., Admiralty Manual of Scientific Enquiry, 1849] should be familiar with all WW's tide papers in the Phil. Trans., but that his tide registry table cannot be at once and simply filled in from observation. It is a registry of results. Each entry is a conclusion from many readings of the tide gage and the clock'. If WW does not approve of Frederick Beechey's forms then he should give some other form. For the methodical observation of the heights and time of high and low water it is best to have printed forms.
