Christchurch, September 4th, 1884,—R. W. Fereday, Esq., 
President, in the chair. 
Professor von Haast read a paper, “In Memoriam: Ferdinand 
von Hochstetter.’”’* 
Professor Hutton said that he did not wish this occasion to pass 
without recording his opinion of the great value of Dr. Hochstetter’s 
geological work in New Zealand. When Dr. Hochstetter came to 
this country a few scattered observations by Dr. Dieffenbach, the 
Hon. W. Mantell, Dr. C. Forbes, and others, represented our know- 
ledge of its geology. All was vague, and no geological map of any 
part of the islands was in existence. During his short sojourn Dr. 
Hochstetier mapped large parts of the provinces of Auckland and 
Nelson, and laid the basis of the present classification of our rocks. 
His geological maps of the neighbourhood of Auckland, and of 
the Waikato and Taupo districts are mervels of accuracy ; and 
in Nelson he was also very successful, notwithstanding the difficult 
nature of the country. He distinguished two tertiary systems, an 
older and a younger, and he recognised the difference in age 
between the coals of Drury and Waikato on the one hand, and of 
Pakawau in Nelson on the other. He also recognised the triassic 
rocks near Nelson, the paleozoic sandstones and slates in the 
southern parts of that province, and the still older schists of the 
western ranges. No doubt the classification in the ‘“ Reise de 
Novara” contains several mistakes, but nearly all ofthese are due 
to Dr. von Hochstetter having incorporated with his own observa- 
tions much information given him by others about pleces he did 
not himself visit. If these be left out, it will be fouid that the 
geological survey has only introduced two changes of any import- 
ance into his classification. The first of these changes is un- 
doubtedly an improvement, but it was not made until 1869. Itis .

of Pakawau and placing them with the older rocks, The second
