also look upper Cambrian, though they are different from those of the Milton. If it were not for the great amount of ochristy we could get more joints. The trouble is to handle across the bedding and ochristy. It can not be done in the three bedded limestones. There is very little dolomite in these Highgate limestones. All in a come a long muddy deposit, In the railway cut I got an entire trilobite site, rather fine specimen but one may be able to make it out. About 300 feet to the north of the above Highgate limestone locality got another whole trilobite. This in a dolomite, and the trilobite shows the edge of. This place must be in the Milton and sometime in the upper Milton but near at the top. It may be over the three bedded ones seen last July in the Highgate Lime. Here the four comes to about 300 feet below the top.
