noon, and as the end of the second day was Saturday at noon, we 

 decided to leave them with double rations, till Monday at noon, for 

 two consecutive days, thus, on the fourth day the mice "A" and 

 "B" from being - about 8^ parts per 100 above, had fallen to 4 parts 

 below their original weights, whilst the "C" mice with Somatose 

 Wine residue rations fell by 13 parts per 100 of their original 

 weights. The mice had evidently eaten all the two days' rations 

 en the first day, and starved during the second. It is remarkable 

 that mice are capable of eating from half to a whole of their own 

 weight of food per day. 



On the fifth day the "B" mice, fed with ordinary Port Wine 

 icsidue rations were 9 parts above their original weight. The 

 "A" which had Glucose in their rations were 5 parts above their 

 original weight, and the "C" series, which had Somatose Wine 

 Residue were 4| parts below their original weights, 



I made another set of experiments, to find how the mice would 

 fare if fed on the rations given in my first series of experiments, 

 but in one series simply leaving out the Somatose without adding 

 anything in its place. Two mice were fed therefore with Oats 2 

 grammes. Plasmon 0.487 gramme. Glucose 0. 15 gramme. Water 

 3.36 grammes — Total 6 grammes, against other two mice fed with 

 Oats 2 grammes. Glucose 0.224 gramme. Water 3.36 grammes 

 — Total 5.584 grammes, this being the same as the ration mixture 

 of my first experiments, but with the Somatose left out. 



The mice fed on the first named or Plasmon ration, each gained 

 weight during the first day, one mouse 7|, and the other, 9 parts 

 above their original weights taken as 100. The other two mice fed 

 with a decreased weight of food corresponding to the weight of 

 Somatose in the ration of my first experiments, each lost weight, 

 the first to 1| and the other to 3^ parts per 100 of mouse. 



At the end of the second day the two mice fed with Plasmon in 

 their rations were respectively 11^ and 15^ parts above their 

 original weights, whilst the other two with decreased rations were, 

 the one J part below, and the other two parts above their original 

 weights. 



At the end of the third day the first two mice fed with Plasmon 

 in their rations were respectively 18 and 18^- parts above, and the 

 other two mice fed with decreased rations, were 1, and 2f parts 

 respectively per 100 above the original weight. 



At the end of the fourth day the first two with Plasmon in their 

 rations were respectively 23 and 24 parts above, and the other two 

 without Plasmon were respectively 3 above, and 1| parts below 

 their original weights. This series proved that whilst the Somatose 

 fed mice in my first 12 days' experiment remained practically below
