MR. J. BALL ON THE BOTAl^Y 



tivation of plants of various regions ; and, althougli it is sur- 

 passed by many others as regards tlio variety of species under 

 cultivation, I have seen very few to equal it in interest. 



Of indigenous plants very few were in flower, but the beautiful 

 Lapagcria rosea in full bloom, climbing over the shrubs and 

 smaller trees, was alone sufficient to adorn the scene. The fol- 

 lowing short list includes chiefly the indigenous plants found on 

 the low cliff's facing the shore, but also at least four species in- 

 troduced from Europe which have apparently become naturalized 

 of late years.

compavatively short period which are available for most of the stations men- 

 tioned below must vary very widely according as years of excessive rainfall or 

 xeeptional dryness happen to be included. As the best available sources I have 



compared the measurements given in millimetrea by Dr. Julius Hann in his 

 ' Handbuch der Klimatologie,' by M. V. Eaulin, in the ' Zeitschrift ' of the 

 Austrian Meteorological Society, vol, xi. p. 137, and by D. B. V. Macienna in 

 the work above cited, for the places of which the latitude is set down.

With two exceptions the figures given by Dr. Ilann and M. Kaulin are 

 evidently derived from the same materials ; but the sum set down by II. Kaulin 

 for Concepcion is anomalously high, while that for Ancud is little over one 

 third of that given by another set of observations. If, as appears probable, the 

 rainfall of 530 millim. at Constitucion is nearly correct, it is not probable that 

 at Concepcion, only 1^° farther south, the average amount is more than twice 

 as great. Having consulted M. Raulin on the subject, that gentleman has been 

 good enougli to inform mo tliat he places no confidence in the result for Con- 

 cepcion recorded by him as expressing the annual mean rainfall of that place, 

 and I incline to believe that even the smaller figure (13G4 millim,) is above the 

 average rate.
