He detailed some of the measurements made of over eight hundred members of the 
Maori Battalion that served in the late war. For full-blooded Maoris he established 
racial standards of 5ft. 7Jin. in height and 11 stone 91b. in weight, which were IJin. 
and 22 lb. greater than those so far accepted on too few observations. Head, face, 
and nose measurements were detailed, and attention drawn to the tribal differences 
that existed. An interesting feature was the modification of face and nose width which 
occurred amongst those of mixed blood, the narrowing in these two measurements being 
shown to increase with the greater admixture of white blood. The whole subject opened 
up a new field of great scientific interest, and further investigation would probably 
throw' additional light on tribal and racial origin, and have an important bearing on 
the culture differences that existed in various parts of New Zealand.

Resolutions of the Science Congress. 
1. That this Congress, recognizing Bacillus amylovorus as being in the 
forefront of destructive plant-diseases, views with alarm its introduction 
into New Zealand, and urges upon the Government the necessity of adopt¬ 
ing the most effective means towards its early eradication, and is further 
of the opinion that it will be little short of criminal not only to the fruit¬ 
grower and general public of the present day, but to future generations, 
should any consideration of expediency whatever be allowed to interfere 
with the vigorous prosecution of such a policy. 
2. This Congress is of opinion that an absolutely complete census of all 
hawthorn hedges or single plants and all other hosts of fire-blight should be 
carried out in conjunction with the forthcoming general census. 
3. That the time has arrived when the Marine Department ought to 
establish systematic observations of the sea temperatures on the coasts of 
New Zealand. In Europe and the United States, where such observations 
have been regularly made for thirty years or more, important economic 
results have been obtained, it being found possible front temperature- 
observations to predict the arrival at certain points of migratory food 
fishes, such as herring, some time beforehand. 
4. That this Congress congratulates the Government on the beginning 
made to equip the Hector Observatory with improved seismological equip¬ 
ment, as urged at the last Congress, and that, owing to the importance of 
seismology to New Zealand, the Congress desires to urge the Government 
to add to the equipment of the Hector Observatory by providing another 
Milne-Shaw seismograph, so that both horizontal components may be deter¬ 
mined, and that a vertical-component seismograph also be provided. 
5. That a sub-committee consisting of Dr. Thomson, Mr. P. G. Morgan, 
and Mr. Donovan (Dr. Thomson as convener) be set up and requested to 
collect available information with respect to the New Zealand occurrence 
of minerals containing suspected isotopes of certain elements, and that this 
be handed to Professor Kobertson for publication in some suitable journal. 
6. That this Congress urges upon the Government and people of New 
Zealand the great importance of accepting the generous offer to New Zea-
