16 Yorkshire Naturalists at Middlesborough. 
beneath a flowering lime in the garden, most of them being 
neatly decapitated. The few whole ones were torpid, though 
living. Two wasps were hovering attentively about them, 
and one was detected in the very act of detaching itself from 
a bee, carrying off something (for it) of considerable size— 
no doubt part of its victim, though we did not see the very act 
of mutilation. The other, though it visited many bees, did 
not happen upon a live one while we watched. Later, a wasp 
settled on the window pane with a similar burden. 
As the weather had been remarkably cold, I came to the 
(perhaps erroneous) conclusion that the bees were benumbed 
by it, as one often sees them in late summer, and so fell an 
easy prey. 
On July 30th, 1891, I noticed the same thing, and again the 
weather was stormy, with a north wind. Out of thirteen dead 
bees, twelve were mutilated; but this time I saw no wasps. 
YORKSHIRE NATURALISTS AT MIDDLESBOROUGH. 
Tue forty-ninth annual meeting of the Yorkshire Naturalists’ Union was 
held .at Middlesborough on Saturday, December 17th, 1910. Notwith- 
standing the many inconveniences as regards the train service, and the 
wretched weather, there was a good attendance of members and delegates 
from all parts of the county. 
The meeting was preceded by an excursion to the Marske quarry, where 
a quantity of the rock was specially blasted for the benefit of the visitors, 
and numerous interesting fossil: plants were gathered, including D7ctyoza- 
mites hawellz. 
In the afternoon, the General Committee met in the Girls’ High School, 
Albert Road, and the report, appearing on pages 33-79, was discussed. 
In it will be found the excursion, etc., arrangements for Ig1T. 
In the evening the Annual General Meeting was held, and Professor 
A. C. Seward, F.R.S. delivered his presidential address entitled ‘ The 
Jurassic Flora of the East of Yorkshire in Relation to the Jurassic Flora of 
the world’ (see pages 1-8), which was illustrated by lantern slides. Re 
was supported by Mr. J. E. Stead, F.R.S., Mr. T. A. Lofthouse, Mr. J. J. 
Burton and others. One pleasing result of the Middlesborough meeting 
was the formation of a Committee for the investigation of the Yorkshire 
Jurassic Flora, particulars of which will be found in the Annual Report. 
It was announced that, on the invitation of the Executive, Dr. Alfred 
Harker, F.R.S., had accepted the presidency of the Union for rgrr. 
After the address an enjoyable conversazione was held on the invitation 
of the Cleveland Naturalists’ Field Club. At this were several exhibits of 
local interest, including a Series of specimens from the Marske quarry ; 
rare local birds, mollusca, lepidoptera, coleoptera, and objects under 
microscopes, etc. Most of the members also took the opportunity of seeing 
the Middlesborough Museum where Mr. F. Elgee is getting an interesting 
natural history collection together.
