Rico Is now a thing of the past, and like all 

 unpronounceable foreign words has sacrificed 

 its life to the dictum of the law of the least ef- 

 fort. It was never used by the American or 

 English people and may now be laid upon the 

 shelf with Nuevo Mejico, Nouvelle Orleans and 

 others of their kind. 



In determining this form of the word the 

 Congress has followed the undoubted usage of 

 the English language for 300 years and scotched 

 an effort to fix upon our people and language a 

 name and a principle which were never accepted 

 by them. Eob't T. Hill. 



LINGUISTIC FAMILIES IN MEXICO. 



To THE Editor OP Science : — In the ^wiencan 

 Anthropologist Q^ . S. , II., 63-65), I have brought 

 Pimentel's list of linguistic families in Mexico 

 into harmony with the scheme of the Bureau of 

 American Ethnology. It occurs to me that it 

 will post the ethnology of the Republic up to 

 date to add the names of families not mentioned 

 by Pimentel, and to spell them in accordance 

 with Major Powell's scheme for North America. 

 Then families, language names, and tribal 

 names will not be confounded. For example, 

 the Mayas or Maya people, speak the Maya 

 language, of the Mayan family. The Mangues, 

 speak the Mangue language, belonging to the 

 Chiapanecan family.

hemianopsia in migraine. 



The visual symptoms frequently occurring 



in migraine ('sick-headache,' so-called) have 



been described (see e. g., Wood's Reference 



Sand-hook of the Medical Science, sub verba) by 



Fms. 1, 2, 3. 



Optical symptom in migraine (Figs. 1-2). 0, point 

 of fixation in center of left hand held laterally 18 in. 

 before the eyes. AB, length of hand. OZ, direction 

 of development of symptom (hemianopsia in left up- 

 per quadrant). Fig. 1. Initial stage, true size 

 (about), only symptom of any sort present. Fig. 2. 

 Maximum stage, accompanied by massive headache, 

 and beginning of nausea. Fig. 3. Final stage ( be- 

 fore rapid fading), violent, more localized headache 

 and nausea. (In Figs. 2 and 3, AO, equals AB ol 

 Fig. 1. ) Daration of symptom 1 to \\ hour. Symp- 

 tom is invariably for recurrent attacks, and for mo-
