LETTER OF TRANSMITTAL. 
Sir,— 
Geological Survey Office, 
Wellington, 1st June, 1917. 
I have the honour to transmit herewith a palaBobotanical 
memoir, or monograph as it may more correctly be termed, which has 
been written by Dr. E. A. Newell Arber, Demonstrator in Palaeo- 
botany to the University of Cambridge, and is entitled “ The Earlier 
Mesozoic Floras of New Zealand.” The memoir, now published as 
Palaeontological Bulletin No. 6 of the New Zealand Geological Survey, 
contains 80 pages of letterpress, and is illustrated by 14 plates in 
collotype and 12 figures reproduced as half-tones or as process blocks. 
A perusal of the following pages will show that Dr. Arber, who, 
solely as a labour of love, undertook the work of examining and describing 
the plant-remains, here described, has spared no trouble and no pains in 
order to make the results of his investigations so complete that the 
Mesozoic botany of New Zealand will henceforward be established on a 
firm footing. The memoir itself will undoubtedly become a classic, indis¬ 
pensable to all students of Mesophytic floras. 
With the exception of the plates, which were executed by the 
London Stereoscopic Company, this bulletin has been prepared entirely 
in the Government Printing Office, Wellington. Thanks and praise are 
due to the Government Printer and his staff for the careful manner in 
which this difficult typographical material has been set up. The first 
proof was read by Dr. Arber, but later proofs were corrected only in New 
Zealand, and therefore a few small errors are doubtless present. It is 
hoped, however, that the corrigenda will be found few in number and of 
little consequence. 
I have the honour to be, 
Sir, 
Your obedient servant, 
P. G. MORGAN, 
Director, New Zealand Geological Survey. 
Hon. W. D. S. MacDonald, 
Minister of Mines, Wellington.
