HALLIFAX stated that he made sealing wax varnish with the best 
sealing wax, crushed fine, and dissolved with a gentle heat in alcohol. 
Mr. W. H. Smiru thought methylated spirits, not the finish of com- 
merce, would do as well, as it was cheaper and 4° stronger than alcohol. 
If a small quantity of the Balsam of Tolu was added it would render

quantity of chloroform in dissolving the sealing wax. When talking 
with the Doctor about the new cement, he understood him to say he

benzole. It worked easily, was far cheaper, and dried readily. Asa 
proof of the last-named quality, some of the slides he had brought 
down had not been made six hours, and were now nearly dry. 
In proposing a vote of thanks to Dr. HALLIFAX, both the Chair- 
man and Mr. G. D. SAWYER considered the information both useful 
and practical. Its importance also might be gathered after the ex- 
amples quoted by Mr. SmiTrH and others. 
Dr. HALLIFAX thought their thanks were due to 
introducing the subject to him, and confirming his observations and 
experiments ; but Mr. Wonror repudiated being anything else but 
a pupil of an admirable instructor, from whom he had constantly re- 
ceived very useful hints in mounting and preparation.

Previous to the above, it was announced that Mr. G. Davrks had 
Presented some rare plants gathered by himself and Mr. Brrcy 
WOLFE, in Sussex, including Lolium temulentum, poisonous darnel, 
Rhinodina exigua var. horiza, and specularia hybrida.—A vote of 
thanks was given to Mr. DAVIEs,
