light. We may perhaps obtain some light on these anomalies by referring 

 to Memoir No. 2, page 162, where it is shown that it is not possible to separate 

 the canes in Baroukha into early and late, by the counting of the number of 

 joints formed, as it is in Pansahi. It is therefore probable that the arrange- 

 ment in the table is not that in order of emergence from the ground. Attention 

 is, however, drawn to the broken lines inserted, as in Nos. 4-6, which are not 

 infrequently parallel with one another and with the end dotted line. It is 

 obvious that, if Canes Nos. 4 and 6 had been placed next to one another, the 

 psriodicity in the two can?s would have been uniform. The same applies to 

 15 and 17 and to 18 and 20 and, in a slightly less degree, to 1 and 4, the con- 

 necting lines in each being approximately parallel with the dotted line. And 

 it is possible that, if we had some reliable method of determining the order 

 in which thes3 canes emerged from the ground, we should be able to compose 

 a diagram showing the periodicity more clearly.
