BORIC ACID AND BORAX.

gain in weight occurring in Series I. In Series II, IV, and V there 

 appears to be practically no tendency to check the loss of weight by 

 reason of the withdrawal of the preservative. The general conclusion, 

 which is based upon these data, is that the administration of borax and 

 boric acid, in the quantities and under the conditions stated, tends to 

 produce a slight loss of body weight. On the withdrawal of the 

 preservative during the short after period there is, in some cases, 

 a tendency toward recovery of normal weight, but in the majority of 

 cases the tendency toward the loss of weight continues. These data, 

 therefore, are capable of interpretation in different ways, in so far as 

 respects the influence of the preservative. The most reasonable inter- 

 pretation is that which has already been given in connection with a 

 study of the individuals in the series. In this discussion the weights 

 of the after period of Series II have been included, although, as has 

 already been intimated, by reason of illness and irregularity, the other 

 data for this after period are not sufficiently reliable to justify their 

 inclusion in the general average of results.
