SCIENTIFIC SUMMAET.

in tlie solution itself, and immediately poured otf, sufficient will remain 
behind for the production of crystals, whicb will form at once. When of 
a sufficient size, the remaining liquor, if any, should be drained from them 
and the slide allowed to dry. The result will generally be a slide, evenly 
covered with crystals, having well-defined edges, and but few of which are 
agglomerated. This process answers well for alum, chlorate of potassium^ 
nitrates of barium and strontium, potassio-tartrate of antimony, sulphate of 
copper, sulphate, acid tartrate, binoxalate, and quadroxalate of potassium, 
the strength being regulated by experience. If crystals are not very soluble 
in cold water, they may be allowed to separate in the bulk of the solution 
itself as it cools, then remove a small quantity of liquids and crystals to a 
slide by means of a glass tube. The slide must be kept moving to prevent 
the aggregation of the crystals, and the superfluous liquid removed by ap- 
plying blotting paper to the edges of the slide. 
A Mia'oscopio Discovery. — Mr. George Henry Lewes, who, as our pro- 
fessional readers are aware, is an adept in the discovery if not in the develop- 
ment of physiological theories, and who employs the pages of the Pall Mall 
Gazette as the scientific (!) platform from which to ventilate what he is 
pleased to style his ^heresies,’ has recently announced to the readers of that 
journal a discovery which he says he made when last in Germany, and 
which he thinks they should be informed of. This discovery is no less than 
that of the existence of a journal called Schultze’s Arcliiv, for microsco- 
pical anatomy. As we have been in the habit for some years of quoting 
passages from this journal, and as our excellently conducted contemporary 
the Quarterly Journal of Microscopical Science, from time to time has pub- 
lished two or three lengthy translations from Schultze’s journal, it certainly 
did strike us as somewhat singular that Mr. Lewes should thus suddenly 
wake up, like a second Hip Van WTnkle, to anew enlightenment. It occurs 
to us, too, as not a little remarkable that a would-be savant like Mr. Lewes, 
who evidently desires to be thought au courant with the labours of scientific 
men, should — as appears on his own showing — have been ignorant of the 
fact that an English microscopical j ournal has an existence, ‘ local habitation, 
and a name,’ and is in every way worthy of the high reputation of British 
histologists. Mr. Lewes might two years ago have seen the journal he has 
just discovered, lying on the table of the College of Surgeons. Like the 
astronomer in the story he has been seeing too far, and projecting the fly in 
his telescope upon the body of the sun. Mr. Lewes is, it seems, one of those 
scientific prophets whom an ungrateful country has failed to honour. 
The Royal Microscopical Society . — The annual meeting of the Society was 
held in February, James Glaisher, Esq. F.B.S., in the chair, and the report 
showed that seventy-four new Fellows had been elected during the year, 
the total number being 451. The auditors’ statement of accounts showed 
that the income of the society from all sources during the past year was 
1,515/. 17s. 2>d., and the expenditure 1,274/. 2s. lid., leaving a cash balance 
in hand of 241/, 14s. Ad. It was also shown that the society possesses a 
large and valuable collection of microscopes and apparatus, a cabinet con- 
taining in all 2,674 slides, and a well-sected library, which, together with 
the famous machine for microscopic writing, are available for the use of the 
Fellows. The president, in delivering his address, warmly congratulated
