Stomach and small guts. Also, why to some animals liquidity of excrements is 

 as necessary. 



Directions for the Use of the following Tide Table, sent by J. F. (John Flam- 

 steed) M.R. and R.S.S. N° 155, p. 458. 



Having found my last year's tide table very agreeable to experience, I here 

 present you with another for the year ensuing, made by the same theory and 

 numbers, but in a more convenient form for your tracts. I must only desire 

 those that use it to note, that when by reason of long droughts in summer, or 

 continual hard frosts in winter, the fresh waters are low, as also when the 

 winds blow hard at N. or N.W. the tides may hold up longer than the times 

 shown in the table. But when the contrary winds blow hard, or by reason of 

 great rains the freshes are increased, they hold not out so long, yet have I very 

 rarely found the difference more than half an hour. I find by inquiry made 

 amongst our most experienced seamen, that the high waters of our English and 

 neighbouring ports, keep a good correspondence with these of the river 

 Thames; having therefore instructed myself the best I could by conference 

 with them, I have made the following table of reduction, whereby the tide 

 table may be made to serve at the places underwritten, by adding,
