48 Mr. A. W. Blyth. Observations on the [May 15, 



Dr. Richardson has published elsewhere* an account of the results 

 of the general clinical observations, and it suffices to remark, that the 

 pedestrian during the whole time enjoyed the most robust health, and 

 at the termination of the walk was apparently in no way the worse 

 for the continuous exertion of so many months. 



My own part in the observations on Weston has been the analysis 

 of the egesta and the calculation of the food equivalents. The latter 

 have been, for the most part, based upon analyses in my own work 

 on " Food," supplemented by the mean numbers given in Kiinig's 

 " Nahrungsmittel," and in two instances by analyses of the actual 

 foods consumed.f 



The Food taken. Inyesta. 



The bulk of the food was taken in three meals breakfast, dinner, 

 and supper. Carbohydrates were supplied chiefly through porridge, 

 bread-stuffs, potatoes, and tapioca pudding; albuminoids through 

 eggs, fish, lean beef or mutton ; some fat was taken in the shape of 

 butter, and there was a copious supply of liquids by means of mutton 

 broth, tea, coffee, and aerated waters ; it is also noticeable that each 

 day a certain number of figs were eaten. Table 1 (p. 47) gives the 

 amounts of the various constituents in grams and cubic centi- 

 metres. 



In Table II the somewhat complicated diet is reduced to " food 

 equivalents." 



The last day, Saturday, was in some points not comparable with 

 the others ; besides which, we have the results of an analysis of the 

 solid excretaj corresponding to the food of the five days, from 

 Monday to Friday inclusive, so that it is best to take the average of 

 the five days previous to Saturday, and this average may be compared 

 with any standard diet which would keep a man of Weston's weight 

 in health during ordinary labour.

The sponge cake was also analysed.' 



J The solid excreta of, say, Tuesday is supposed to belong'to Monday's food, that 

 of Wednesday to Tuesday, and so on ; but as the urinary secretion is expelled more 

 frequently, most of a day's urine belongs to the diet of that particular day, and in 

 this paper is supposed to wholly belong to the same day.
