116 REPORT—1862. 
solar spots with an ordinary telescope, or by data obtained by the Astrono- 
mical Observatory as part of its own work. 
Besides the excellent collection of magnetic instruments (one of the finest 
and most complete in existence, with scrupulously determined constants) 
which is thus placed in the possession of the University of Coimbra, Prof. de 
Souza has blank forms for the record of all the observations, and the formule 
for their reduction, collected both from the instruction given to him at Kew, 
and from his own careful examination of the manuscript books of the Ob- 
‘servatory. 
The magnetic instruments have arrived safely at Coimbra, and measures 
have been taken for the similar conveyance of the meteorological instruments. 
Mr. Beckley’s drawings furnish all the data for the construction of the 
building, which will be simple and of small cost. An estimate, M. de 
Souza says, is appended; but it does not appear in the printed report. 
M. de Souza further alludes to his having reported, both to the University 
and to the Government, his attendance at the Meeting of the British Associa- 
tion at Manchester, as a member of its Committee of Mathematics and Physics, 
where he was enabled to enter into relations with the distinguished men 
assembled there from all parts, some of whom were Directors of Observatories, 
who promised the accounts of their results, and would doubtless expect his. 
The British Association has granted a complete copy of their annual Reports 
from the commencement, and with these and the works previously received, 
the Coimbra establishment would find itself at once in possession of a good 
library of the best writings on the subjects of its investigations. He once 
more recalls all the kindness and assistance he received in England, adding 
that the Royal Society granted £30 from their ‘Donation-fund” for the 
expenses of the verification of the magnetic instruments prepared for the 
Coimbra Observatory, and concludes by urging the completion of the arrange- 
ments for an establishment which he trusts will prove alike honourable to 
his University and to his country. 
Report on the Dredging of the Northumberland Coast and Dogger Bank, 
drawn up by Henry T. Mennett, on behalf of the Natural History 
Society of Northumberland, Durham, and Newcastle-on-Tyne, and 
of the Tyneside Naturalists’ Field Club. 
Tue Committee to whom the grant of the Association for « Dredging on the 
Dogger Bank and the coasts of Northumberland and Durham” was entrusted 
having, at the request of the Natural History Society of Northumberland, 
Durham, and Newcastle-on-Tyne, and of the Tyneside Naturalists’ Field 
Club, courteously committed the practical carrying out of the proposed inves- 
tigations to these bodies, their members contributed the large sum required 
in addition to the Association grant, and I have now to report the result of 
our labours. 
The dredging took place at the end of August; hence the time which has 
since elapsed has been too limited to do full justice to the specimens obtained 
in many departments. 
It was confined to the following localities: Ist, on a line due east of 
Tynemouth, extending to the Dogger Bank, a distance of about 100 miles. 
The dredging commenced about twenty miles from land, was resumed at
