INTRODUCTION.

The compilation of a work of this nature is impossible witliout the 
help derived from others, and I have to acknowledge free use of the 
London, Vienna, Paris, BerUn, Washington and Chicago catalogues 
by Fletcher, Brezina, Berwerth, Meunier, Klein, Tassin, Ward and 
Farrington respectively. In addition to these I am also indebted 
in no small degree to the classical works of Wulfing, Cohen and 
others. The weights of falls which are only represented by fragments 
of less than 0*5 gram are not given. The names of Indian falls are 
printed in italics {e.g. AKBARPUR) and the first reference to them in 
literature is added. 
Finally, it is hoped that this catalogue will not only serve a use- 
ful purpose in the conservation and building up of the Calcutta col- 
lection, but that it will also help in the advancement of our know- 
ledge of meteorites in general. In this connection, attention may 
be drawn to the fact that I have determined the position of the 
following falls which were left unclassified by Wulfing, — Kakan- 
garai, Linum, Nageria, Perth, Sabet Mahet. I have also provi- 
sionally classified numerous recent Indian falls including— Bholgati, 
Delhi, Donga Kohrod, Haraiya, Kamsagar, Karkh, Kuttippuram, 
Lakangaon, Meerut, Mirzapur, Shupiyan.
