whose index averages about 90. On the 

 whole the broad-skulled type predominates, 

 being, as compared to the long-skulled type, 

 in the proportion of S to 3. The complete

BIBLIOGRAPHY OF PERU. 



The 23d publication of the Field Colum- 

 bian Museum is a ' Bibliography of the 

 Anthropology of Peru,' by Dr. George A. 

 Dorsey. It is a neat octavo of 206 pages 

 and must contain nearly 3,000 titles. This 

 is proof enough of its value to students, and 

 we venture to hope that it will not be the 

 last work of the kind by its author, though 

 in his preface he says it will be. 



How impossible it is, however, to reach 

 completion in such a task ! Confining 

 myself to the works in my own library, I 

 find that Dr. Dorsey does not mention the 

 papers on Peruvian mummies by Schuch 

 and Cornalia, nor that on Peruvian gems 

 by Blondel, nor any by the distinguished 

 collector. Dr. Contzen, nor the valuable 

 archaeological catalogue of Macedo, nor the 

 essays on Peruvian mythology by Lafone, 

 and, more painful to relate, he says nothing 

 of my articles on the Puquina language 

 omitting also those of Grasserie on the same 

 tongue. This merely shows that the great- 

 est care sometimes fails. 



THE LAMP OF THE ESKIMOS. 



It has been noted that no form of lamp 

 (with one doubtful exception) was known 

 in ancient America south of the Eskimos. 

 These possessed one from time immemorial. 

 They could not, indeed, live without it. 

 A study of it is presented in the Ameri- 

 can Anthropologist for April by Mr. Walter 

 Hough. He considers it an independent 

 invention. The rudest are merely stones 

 collected on the beach with natural con- 

 cavities in which the fats or oil can be 

 poured and the wick laid at the side. 

 Other stones were hollowed out to imitate 



these. At St. Lawrence Island lamps of 

 pottery are frequent. The size and form of 

 the lamps curiously enough bear so distinct 

 a relation to the isothermal lines that it is 

 possible by comparison to assign the geo- 

 graphic position to any specimen.

SCIENTIFIC NOTES AND NEWS. 



SUMMER SCHOOL OF THE ILLINOIS BOTANICAL 



STATION. 



A SUMMER school of blology will be held at 

 the Illinois Biological Station, Havana, Illinois, 

 under the auspices of the University of Illinois, 

 adapted to the purposes of university students ; 

 the instruction will also be carefulljr adjusted 

 to the needs of teachers of biology wishing an 

 opportunity for personal studies, in field and 

 laboratory, of the plants and animals of a pecu- 

 liarly rich and interesting situation and of the 

 methods of modern biological station work. 

 Four regular courses will be offered to organ- 

 ized classes, two in zoology and two in botany ; 

 and in addition to these opportunity will be 

 given to students of experience to take inde- 

 pendent work on special subjects, and to visit- 

 ing investigators to pursue their personal re- 

 searches at the station with the use of its 

 equipment. The regular courses will be open 

 to all who satisfy the management of their 

 abilitj' to do the work. The session will begin 

 June 15th and continue four weeks, but mem- 

 bers of classes may continue their work inde- 

 pendently until August 1st. "Visiting investi- 

 gators may come at any time and remain until 

 September 1.5th, and teachers may enter at any 

 date preceding July 1st. 



Visiting investigators will be given tables 

 on the floating laboratory of the biological sta- 

 tion. They will find in the locality a very rich 

 fauna and flora iu a greatly varied environment. 

 Exceptional opportunities are oflfered for work 

 on the lower algre and the fleshy fungi. Over 

 ninety species of Mycetozoa occur at Havana 

 during the summer months. The abundance 

 of Protozoa, Rotifera, Entomostraca, aquatic 

 insects, planarians, oligochsete and parasitic 

 worms, Mollusca — especially Unionidas and
