328 C. U. C. P. ALUMNI JOURNAL August, 1918 



While this may be considered a law not directly affecting clinical and diag- 

 nostic laboratories, it does cover, however, the use and possession of hypodermic 

 syringes and needles which are so often necessary in obtaining various body fluids 

 for examination, and in the procuring of blood for various biological, chemical and 

 serological tests. They are both indispensable for the injection of animals with 

 various pathological elements, for the purpose of determining their biological and 

 bacteriological aspects. In conclusion, as a finale to date, we have one more law 

 that diagnostic and analytic laboratories will be obliged to comply with. This law 

 is known as the Federal Explosives License. It requires that a license be taken 

 out by every person using ingredients that enter into the making of various ex- 

 plosives and detonators during a time when the United States is at war. In fact, 

 I have recently been advised that ether and chloroform are now refused to pur- 

 chasers by dealers and manufacturers, unless they produce their explosive license. 

 We are all aware to what extent alcohol has been restricted for munition purposes, 

 and it is no wonder that the above have come under the ban. What now follows 

 in the above law is the so-called "Analyst's Explosive License," which reads under 

 act of Congress, H. R. 3932, Sec. 10 — part (g) — "Analysts, educators, inventors 

 and investigators licenses authorizing the purchase, manufacture, possession, test- 

 ing and disposal of explosives and ingredients." 



These licenses are issued by the Director of the Bureau of Mines under au- 

 thority of the Department of the Interior, through the various county clerks. In 

 applying for the above license, an exception is made in this particular case, which 

 does not apply to the other six licenses and is, as we should know, made for ob- 

 vious reasons, which is : "an application for an analyst's license must be indorsed 

 under oath by two responsible citizens, acquainted with applicant and known to 

 the licensing officer." This act was approved on October 6/1917, and covers a 

 certain number of chemicals largely used for special purposes in clinical and ana- 

 lytical laboratory methods, which also enter into and come under the general head- 

 ing of explosive ingredients. In order to purchase, possess, use or offer for sale 

 any of the ingredients listed below in amounts of one ounce and over, a Federal 

 Explosives License will be required. The approved list of ingredients which are 

 used in laboratory methods as above intimated, is as follows : 



Bichromates — ammonium, potassium, sodium. Chlorates — barium, potas- 

 sium, sodium, strontium. Chromates — ammonium, barium, calcium, chrome green, 

 chrome yellow, potassium, sodium. Nitrates — ammonium, barium, copper, ferric, 

 lead, magnesium, nickel, potassium, silver, and strontium. Nitric Acid — aqua 

 fortis, fuming nitric, acids, of all grades and strengths, mixed acids. Pcrchloratcs 

 — perchloric acid, potassium. Perborates — magnesium, sodium, zinc. Perman- 

 ganates — calcium, potassium, sodium. Peroxides — 'barium, calcium, magnesium, 

 oxon (cubes and cartridges), sodium, strontium, zinc. Phosphorus — This would 

 also include flashlight powders and fireworks. 



A purchaser of the above ingredients must file with his dealer, jobber or man- 

 ufacturer, a certified copy of his license before deliveries can be made. The mere 

 information of a customer's license number is held not to be sufficient evidence to 

 justify shipments or deliveries, within the meaning of the act.
