Diaphtherin (diaphtheiro = to completely destroy). The title refers to 

 the antibactericidal properties of this quinolin derivative. 



Quinaseptol (a = negative + SEPO = to putrefy'). A quin-o\\n deriva- 

 tive of antiseptic properties. 



Kairin (kairos = a?i opportunity). Oxy-quinolin-ethyl-hydrid. 



Kairolin (kairin + oleum = an oil). Quinolin methyl or ethyl hy- 

 dride, an oily liquid. 



Thalline (thallos = a green twig). 



Loretin. Named by Professor Claus, the discoverer of this meta-iodo- 

 ortho-oxy-quinolin-ana-sulfonic acid, in honor of his daughter Laura. 



Some Bismuth Organo-Preparations. 



Dermatol (derma = skin). Basic subgallate of bismuth. 



Helcosol (elkos = an ulcef). Basic pyrogallate of bismuth. 



Thioform (theion = «^«r + forma = /(?m (sf.)). A basic di-thio- 

 salicylate of bismuth. 



From the examples cited it will be observed that chemical nomenclature 

 is retained in all cases where at all practicable ; however, the majority 

 of these synthetic products possess such long chemical titles that their 

 employment is out of the question. No matter what valuable medicinal 

 properties a remedy may possess, its failure or success depends largely 

 upon its title. What would have been the fate of Loretin had its chem- 

 ical title been preserved, or that of Eucain A, with its chemical title of 

 sixty-two letters ? and so on with many others. The medical fraternity 

 and commercial world have no use for medicinal products possessing long, 

 complicated chemical titles ; hence the necessity of selecting a convenient 

 euphonic title which is readily retained in the memory.

The ©hemistry of Aloes.- 



By Alfred R. L. Dohme, Ph.D. 



Aloes is the concentrated juice of the plants of the genus Aloe, princi- 

 pally the varieties Aloe socotrina, Aloeferox, Aloe plicatilis, Aloe vulgaris, 

 Aloe Africana and Aloe Perryi. Strange to say, the much-talked-of and 

 official Socotrine aloes does not grow on the island of Socotra, this variety 

 being Aloe Perryi, named after our famous Commodore Perry, who ob- 

 served it on the island in 1878. Commercially speaking, the varieties of 

 aloes are Socotrine, Curacoa, Barbadoes, Natal, Cape and Indian aloes.
