The date of C. Agardh’s Species Algarum. 
A question having been put to me about the actual da- 
tes for the printing and publishing of the different parts of 
C. Agardh’s Species Algarum, it may be advisable to pub- 
lish my answer here. 
The first volume of C. Agardh’s Species Algarum was 
printed in Lund in 2 partes. On the title page of pars prior 
we read: Lundæ MDCCCXX. Ex officina Berlingiana; and 
on pars posterior: Lundæ MDCCCXXII — — — — . 
But other years often are quoted in consequence of other 
title pages by the publisher. On that of pars prima is prin- 
ted: Oryphiswaldiæ sumptibus Ernesti Mauritii MDCCCXXI; 
and of pars posterior: — — — MDCCCXXII; and on that 
of volumen primum: — — — - — MDCCCXXIII. 
Among the letters to C. Agardh now kept in the lib- 
rary of the University of Lund, there are several letters 
from Mauritius. In one of these from the year 1820 
Mauritius accepts a contract of publishing, sent to him by 
Agardh, but the contract itself is not there. 
That pars prior had been both printed and published 
in the year 1820 can be further demonstrated by the All- 
gemeine Litteratur-Zeitung 1820, Bd. 3, N:o 329, Avhich num- 
ber is the last but one of December 1820. 
The specimens of this volume 1, I have seen, are all 
quite alike, from one single printing, with the exception of the 
two kinds of title pages. But of pars prior I have seen one speci- 
men (ATiardh’s own) printed on a finer paper than the others. 
All agree in the opinion that voluminis secundi sectio 
prior was published Gryphiæ 1828. 0. Nordstedt.
