With reference to a Circular issued by a Committee of the British 

 Association for the purpose of collecting photographs of Anthropological 

 interest, printed in the Proceedings of the Society for April 1903, the 

 President announced that the Council had agreed to the establishment 

 of a local Indian depot for the storage of negatives, and the Society had

 The Council had further undertaken the business of the lecture itself at

 and entrusted the matter to a Sub-Committee consisting of the Vice- 

 President, Mr. E. P. Stebbing, the Hon'ble Dr. Asutosh Mukhopadhyaya, 

 and the General Secretary. Members of the Society will be admitted 

 free and tickets sold to Scientific Institutions at a large reduction.

 Presidency, and made a few remarks upon its life-history. The 

 insect, of which specimens of the various stages and diagrams were 

 shown, belongs to the family Psychidae, commonly called the bag- 

 worms because of the habit the larvaa have of preparing for them- 

 selves early in life small cases of bits of stick, leaves, etc., in 

 which they live and pupate. In the present instance the case is 

 made of the small green branches of the tree arranged in a cylin- 

 drical manner. The green soon fades, and the case then assumes 

 the dirty grey colour of pieces of stick. The caterpillar feeds upon the 

 needle-like leaves of the tree, and its protective case doubtless helps to 

 protect it against birds which, owing to the very thin foliage of the Ca- 

 suarina, would quickly see it feeding upon the tree had it not some form
