 the summer to join the Illecilliwaet River.

No. I — When received at the laboratory (Aug. 15th.), the sample 

 was quite murky, almost milky in appearance, from the 

 presence of suspended mater. On standing 48 hours, a con- 

 siderable amount of what proved under the microscope to be 

 chiefly very fine fragments of quartz had settled to the bottom 

 of the bottle. The supernatant water was, however, still 

 turbid, and remained more or less so — though gradually 

 clearing — for nearly two months. 



No. 2 — This sample also was milky and turbid when received, 

 but not to such a degree as No. i. 



On Dec. 12th, the samples then being perfectly clear and 

 brilliant, the " total solids " of the supernatant waters were 

 again taken, with the following results: —
