list of the Myriapoda* and Arachnoida+. The Infusoria have been little 
attended to: some native genera and species placed by some authors in the 
Animal Kingdom are described in Harvey’s ‘ Manual of the British Algee :’ 
others of a similar nature have been brought before the Microscopical So- 
ciety of Dublin by Capt. Portlock { and Mr. David Moore§. Dr. Geo. J. All- 
man || has likewise exhibited to that Society a few species of Jnfusoria, which 
it is unnecessary to name here. 
In concluding this Report, it may be permitted me to state that no one 
can be more sensible than myself of its numerous imperfections. With the 
hope of diminishing their number by a more extended time, I was desirous of 
its postponement for another year, but it was urged that a Report on the 
Fauna of Ireland should be brought forward at an Irish meeting of the Asso- 
ciation, and to this consideration I at length waived my desire for a longer 
period of preparation. 
PROVISIONAL REPORTS AND NOTICES OF PROGRESS IN 
SPECIAL RESEARCHES ENTRUSTED TO COMMITTEES 
AND INDIVIDUALS. 
Report on the Results of the Discussion of the Meteorological Ob- 
servations made at Plymouth and Devonport at the request of the 
Association. By Wm. Snow Haruis, F.R.S. 
THE great mass of the results which these observations necessarily involved 
had precluded the possibility of completing a full report, such as would be re- 
quisite for the pages of the next volume of the Association: the necessary 
documents are, however, sufficiently complete to insure this report for the 
next meeting. 
The first series of observations were those deduced from Mr. Whewell’s 
anemometer, by which a result has been arrived at not dissimilar from that 
laid before the Meeting at Manchester, viz. the existence of a sort of trade- 
wind or current of air from south to north, in the place where the observa- 
tions were made: this was exemplified by large typographical delineations of 
the aérial currents by lines proportional to the velocity and direction for 
given times laid down for the years 1841 and 18492. 
Mr. Harris made some observations on the nature and capabilities of this 
instrument, and the results which might be expected from it in deducing the 
great annual movements of the atmosphere, 
The result of the discussions of the observations with Osler’s anemometer 
were next brought under consideration, which being regularly tabulated and 
discussed, indicated a mean hourly intensity of the wind in an order similar

Seal (Halicherus gryphus) killed on the Dublin coast by Mr, R. Ball, has been inves- 
tigated by Dr. Geo. J. Allman, who brings it under Arachnoida and constitutes a 
new genus—Ha/larachne—for its reception. He proposes to call the species Halar. 
halicheri: it will be described in the Annals of Natural History.
