Table Mountain without iny net, that the Capetown water supply 

 is derived from two large reservoirs which have been constructed 

 on the top of the mountain. Having lost my way, and seeing the 

 lake in the distance, I went to a small house near it where I found 

 the keeper, a Dane, who told me that he had lived there with his 

 family in charge of the reservoirs eleven years, and that often 

 in the winter he was snowed up for ten days or a fortnight at a 

 time. Every cloud that passes over Capetown settles on Table 

 Mountain and forms the " Table Cloth " ; in consequence of this 

 the plateau and valleys on the top of the mountain are very moist, 

 and covered with vegetation, heathers and brushwood, and I even 

 saw some extensive bogs there from which, no doubt, the Cape- 

 town water derives its slightly brownish tint. From the lakes the 

 water is led by iron pipes into lower reservoirs at the foot of Table 

 Mountain and on the highest ground of the town. One of these 

 is situated close behind the Mount Nelson Hotel, and from it 

 I obtained — 



Synchasta pectinata Ehrbg. Abundant. 

 Anurcea aculeata var. valga Ehrbg. Few. 



Cladocera were very abundant in this water, and their lively 

 movements astonished the keepers, who informed me that this water 

 was delivered to the town without further filtration. 



In the garden fountain of the Mount Nelson Hotel I found 

 only— 



Anurcea hypelasma G-osse ; 



and on the top of Signal Hill, a short distance behind the signal 

 station, from a small cattle-pond I obtained — 



Hydatina senta Ehrbg. Abundant. 

 Brachionus Bakeri Ehrbg. Abundant. 

 Callidina sp. ? 



These rather small B. Bakeri vary from the common European 

 form, in having the posterior spines of the lorica turned more or 

 less upwards. The same pond contained a large ciliated Infusorian, 

 in shape like a three-pronged arrow-head, which I believe to be 

 new. The above six species were the only Eotifers observed at 

 Capetown, but I am quite sure that a much greater number could 

 have been found had I had more time and better opportunities. 

 The large ornamental basin in the Public Gardens had just been 

 emptied when I arrived with my net to examine the water, so that 

 I lost this opportunity. 



Leaving Capetown on the Friday evening, August 18, by train, 

 I arrived in Durban on the following Tuesday morning, August 22, 

 without stopping more than half an hour at any place on the way
