sion and multiplication of the encysted mass. He pointed out 
the importance of Chlamydomyxa for the theory of the vege- 
table cell-wall and its laminated structure, and he was led to 
compare the encysted condition of Chlamydomyxa with the 
encysted condition of such forms as Heematococcus and Glao- 
capsa. He also made important observations on the red- 
coloured oily substance formed in the cysts. 
I frequently searched for Chlamydomyxa in the years fol- _ 
lowing the publication of Archer’s paper whenever I found 
myself in a moorland country with Sphagnum bogs. In the 
neighbourhood of Lervik, on the Stavanger Fjord in Norway, 
I searched in vain, as also on Dartmoor. I was, however, 
rewarded for my coutinued efforts by at last finding 
Chlamydomyxa in abundance on August 22nd, 1886, on the 
surface of Sphagnum gathered in small ditches cut in the 
bog which occupies clearings in the pine-wood at Pontresina 
in the Enghadine; and on two subsequent visits to Switzer- 
land at the same time of year, once at Zermatt (1890) and 
later again in the Enghadine (1892), I found and studied 
Chlamydomyxa. 
On the first occasion when I found Chlamydomyxa, viz. in 
August, 1886, at Pontresina, I was fortunate in being able to 
observe and draw specimens which expanded their remarkable 
networks under the microscope, and I showed such active 
specimens in the Hotel Saratz to my friend Ernst Haeckel, 
who happened to arrive there for a short holiday, and to Sir 
Edward Fry—a judge not only of legal but of biological 
matters. My drawings then made are reproduced in Plates 
14 and 15, figs. 1—4. I was able to recognise the cysts 
which accompanied the naked Chlamydomyxa as belonging to 
the latter, and, indeed, should have recognised them from my 
previous familiarity with the encysted specimens sent to me by 
Archer. But I have never seen expanded Chlamydomyxa 
since that first occasion. At Zermatt and at the Maloja in 
subsequent years I found only the cysts, and no persuasion 
which I could offer was sufficient to induce the Chlamydomyxa 
to leave its cyst. The cysts, however, were always very abun-
