The Crystal Palace Aquarium
After moving in 1854 to its (supposedly) permanent home on Penge Common, the Crystal Palace experienced the first of many fires in 1866, which led to the destruction of its northern end. The site was left desolate for a few years, until a plan was made to construct a marine aquarium, which opened in 1871.
It was briefly the largest of its kind in the world, holding (at least) 100,000 gallons of seawater. This was brought in by train from Brighton, and most was stored in great reservoirs below the floor level. Steam engines constantly pumped the seawater from the reservoirs below to the tanks above – 60 in all, with 38 for public display and 22 for research and storage. The display tanks varied from 40 to 4000 gallons in volume, containing (according to The Illustrated London News) “a large and varied collection of living marine animals, from very small ones to those of considerable size.” The most popular creature was an octopus, which delighted and terrified Victorians in equal measure, and contributed to the craze of cephalomania (said to have been started by the publication of Victor Hugo's novel Toilers of the Sea five years earlier, which featured a giant octopus).
Despite its wonderous displays, the aquarium was not a financial success. In the 1890s, the tanks were drained, and the marine creatures replaced with monkeys. The fire of 1936 that destroyed most of the Crystal Palace left the aquarium mostly untouched, but the demolition by dynamite of its neighbouring water tower in 1941 and construction of the transmitting station would leave only a small section remaining.
This can still be seen today, tucked away at next to the gates to the transmitting station and out of view form the more well-known remains of the Palace’s terraces. The remnants consist of three public tanks (with some original rock face at the rear), underfloor reservoirs (now filled with rainwater), areas where the steam engines would have been, and even the food preparation area and an office, plus a doorway which would have led to coal storage. The Crystal Palace Foundation has been involved in the excavation and conservation of the site, trying to make the site into more of a visitor attraction, and even hopes to one day restore one of the tanks to working use!
How is fish as a protein source for dogs? I know it’s common for cats, but I’m seeing some fish based diets for dogs and can’t help wondering if fish is a good protein for them.
Fish is a totally fine protein for dogs.
As long as the food in question is complete and balanced, appropriate for the dog’s life stage, and formulated by a veterinary nutritionist, it’s fine.
