distribution of these forms that is of primary importance, whether 



or not their interrelationships be closer thanjn the case of the 



first mentioned species. 



It is intended to make a statistical examination of the material 



collected, and of the strength of inheritance in the case o color 



and form characters as determined by the correlation between 



the adults and their young. A full report must await such an 



extended study. Of the live snails, of which there are now more 



than 8,000, it may be said that the adults are now feeding and 



producing young, in some cases four months since their collection ; 



the adolescents are also feeding and growing, and, if opportunity 



permits, will serve for the study of inheritance in direct and 



hybrid lines.

III.— THE EXPEDITION TO THE BLACKFEET INDIAN 

 RESERVATION. 



URING the past summer the writer made another 

 visit to the Blackfeet Indian Reservation in the 

 United States to secure further information as to 

 the ceremonies and industries of this interesting 

 tribe of Plains Indians. The work was quite 

 successful and the IMuseum has now a large collection with full 

 ethnological notes covering the whole range of their culture. 



A number of interesting survivals of ancient industries were 

 observed. In an out-of-the-way camp some w^omen were dressing 

 cow-skins with broken stones instead of the native-made metal 

 tools now in use. For removing the hair a pebble with a broken 

 edge was used, the stone being held in the hand and a glancing 

 blow delivered upon the skin as it lay upon the ground. While 

 this method requires more time than that employing metal tools, 

 it has an advantage in that the danger of cutting into the texture 

 is avoided. In former times the skin was reduced to the required 

 thickness by scrapers flaked from quartzite boulders. 



In another camp an old man gave a demonstration of a type of 

 cooking often employed by the buffalo hunting Indians when 

 on the war-path, a method that may at one time have been the 

 usual manner of cooking. At the demonstration witnessed this
