on hand. To purchase alcohol at the regular mariet 

 price, which is about two and a half dollars per gallon, 

 entails upon the laboratory a serious expense, which, 

 with little trouble, may be avoided. By act of Con- 

 gress every incorporated educational institution is per- 

 mitted to purchase alcohol free of the internal revenue 

 tax when the alcohol is to be used for scientific pur- 

 poses only. Before the alcohol may be withdrawn from 

 the bonded warehouse in which it is stored, certain pre- 

 liminaries must be performed. These are as follows: 

 From the collector of internal revenue for your district 

 learn where the nearest distillery is located ; write to the 

 distiller, specifying the amount of alcohol desired ; in re- 

 turn you will receive a bond, an application for the with- 

 drawal of alcohol from bond, and a ganger's receipt 

 specifying the number, etc., of the package of alcohol 

 which has been set aside for you ; you will then fill out 

 the application with the name of the institution, curator, 

 etc., and forward it to the Secretary of the Treasury, 

 along with the ganger's receipt and the bond, the latter 

 having been signed previously before a notary -public, 

 and in the presence of two witnesses, by the principal 

 officer or curator of the institution and two sureties. 

 In due time the distiller will receive from Washington a 

 permit for the withdrawal from bond of the package of 

 alcohol which you wish to purchase. This will then be 

 forwarded you. By observing such procedure alcohol 

 may be obtained for about seventy-five cents per gallon, 

 or less thkn one-third the market price. 



Absolute alcohol comes in one-pound bottles, and is 

 used as a killing and hardening agent. Objects killed in 

 this may be preserved in seventy per cent, alcohol. 

 Preparation. — As procured in the market or from the dis- 

 tillery, alcohol varies from ninety to ninety-five per cent, 

 in strength. From this the various grades may be pre- 

 pared approximately by mixing ninety -five per cent, 

 alcohol and water in the proportions given in the fol- 

 lowing table :
