himself in the British Museum show A. directiis to be totally 

 distinct : " x 5" should be " x 4," and the material upon which my 

 plant is growing is not a dead leaf, but part of the cone of an 

 Encephalartos. A. craspedius is not from a drawing of mine, but 

 from one by Mr. Saunders. A. acerinns, taken from my drawing, 

 should be A. sponf/iosus, and the description on the plate, "On stump, 

 Walthamstow,' , stands on my drawing, "In a rotten beech, Epping 

 Forest, near Walthamstow." In A. gadinioides two of the figures 

 are not mine. In A. atro-candeus one example appears to be 

 springing from blue mycelium ; in my original drawing this colour 

 belongs to the blue pileus of an example beneath, omitted in 

 Illustrations. In A. Taylori one example and two of the three 

 sections are not mine. In A. eximius the smaller example is half as 

 large again in my original, and the deep furrows shown in top of 

 stem in the larger specimen do not exist in the original, with which 

 the colour of the gills in copy does not agree. In A. f rumen taceus,

and the spores of the fungus illustrated should be white, not pink. 

 This instance shows how unwise it is to take the general aspect of 

 a fungus from one source and the spores from another; as my 

 name is put to Dr. Cooke's plate, I am of course there credited 

 with the coloured instead of white spores. A. Saundersii is not 

 from my original, but from a drawing by Mr. Saunders, hence the 

 specific name given by Fries. 



The above are but trifling slips, perhaps inseparable from so 



extensive a work as the Illustrations, but it is well they should be 

 set right.

Central Provinces. 



1875. Humidity and rain on the whole deficient ; no data for 

 cloud. Conditions unfavourable to both host and parasite, but 

 especially to the latter. Outturn rose. 



1876. Conditions much the same. Outturn very slightly in 

 excess of the previous year. 



1877. Humidity, cloud and rain, all in excess. These condi- 

 tions (not being extravagantly excessive) are favourable alike to 

 general vegetation and to the growth of the parasite. The fall in 

 outturn, and rise in prices, may in this case be attributed with 

 considerable probability to the parasite ; otherwise we should have 

 expected a high outturn. 



1878. Humidity on the whole excessive (except in March); 

 cloud on the whole somewhat excessive ; rain excessive (except in 

 March). These conditions are favourable both to the host and to 

 the parasite, but especially to the latter. As the outturn fell
