ture, has a single glyph carved upon its front. This is quite clearly the 

 day 8 Ahau and in all probability denotes the katun ending 9.13.0.0.0 

 8 Ahau 8 Uo. This is also the latest date on the tablet of the Foliated 

 Cross in the temple of the same name nearby, and on the tablet in the 

 Temple of the Inscriptions across the stream, and is possibly to be 

 interpreted as indicating that these three temples were all dedicated on 

 the same day. 



In spite of certain architectural evidence to the contrary, it seems 

 fairly clear from the seven or eight dates now known at Palenque, that 

 the city was at its zenith about 9.13.0.0.0 and not a hundred years 

 later, as has been suggested. Indeed 9.13.0.0.0 is the latest date that 

 has yet been found there. Beautiful as the Palenque sculptures are — 

 possibly the best in the whole Maya area — their excellence may prob- 

 ably be ascribed to the superiority of the sculptural media, stucco or a 

 very fine-grained limestone, rather than to a later period of origin, and 

 the city itself had probably already reached the zenith of its esthetic 

 development before the beginning of the Great Period in 9.15.0.0.0.*

Garrison, Fielding H., Army Medical Museum, Washington, District of Col- 

 umbia. Preparation and publication of the Index Medicus. (For pre- 

 vious reports see Year Books Nos. 2-16.) 



The Index Medicus for 1917 represents 682 pages of bibhographic 

 material, with an index of 134 pages. The restricted size of the annual 

 volume is a measure of the response to national crises by physicians and 

 scientists and of the difficulty of obtaining foreign medical periodicals. 

 Transactions of medical societies and congresses in normal times furnish 

 a substantial quota of references and the cancellation or postponement 

 of these meetings is reflected in a reduced quantity of medical litera- 

 ture. Continued preponderance of war literature is manifest through- 

 out and has necessitated the introduction of additional subject rubrics 

 under the section of Military Medicine. A War Supplement, consti- 

 tuting a classified bibliography of medico-military literature, has also 

 been issued. It embraces some 12,000 items in 260 pages and furnishes 

 references to subjects of military interest from January 1914 to Decem- 

 ber 1917. A new type-page has been designed to facilitate more ready 

 reference. 



* A correction should be noted here in the report of the previous year's work. On p. 288 of Year 

 Book No. 16, attention was called to the discovery of the ruins of Los Higos in the Chamelecon 

 Valley, Honduras, through information derived from Mr. S. K. Lothrop, of Harvard University, 

 and Mr. Basil Booth, of Guatemala City. Credit for this discovery, however, it has been sub- 

 sequently ascertained, belongs instead to the well-known Central American traveler, E. G. 

 Squier, who visited this site as early as 1850, and who seems to have published his first account 

 thereof in Frank Leslie's Magazine for April 1883; "Ancient laborers and princes of Grand Chimu 

 and New Granada." E. G. Squier, Frank Leslie's Magazine, vol. xv. No. 4, April 1883, pp. 

 468-480. Although he was unable to read the hierogljrphic inscriptions there, his visit having 

 antedated by more than 30 years the first successful attempts at decipherment by Professor 

 Ernst Forstemann and J. T. Goodman, Squier's priority of discovery remains unquestioned and 

 any credit arising therefrom belongs to him; acknowledgement of which is made here.
